[ Pulp and paper making Pulp and paper making Broad suite of dedicated solutions to increase efficiency and minimise environmental impact in pulp and paper production Ask for advice Challenges and transformations in the pulp and paper industry Although the pulp and paper industry is growing as a whole – driven largely by rising demand for packaging, tissue paper and pulp for hygiene products – there are various challenges on the horizon. According to experts at McKinsey & Company, this sector is going through the most substantial transformation it has seen in many decades, prompted by structural changes, consolidation, and ever-rising specialisation. Given dwindling newspaper sales, for instance, many paper mills are looking to position themselves for growth by converting from graphic to packaging paper. In the search for value-creating growth opportunities, many pulp mills are also looking to branch out into biorefinery products. Enhancing efficiency and sustainability Many key players in the industry rely on us, for instance, to help increase capacity without investing in new and larger equipment, reduce dependence on hazardous chemicals, improve pulp washing efficiency and stabilize pH, alkalinity and calcium levels in papermaking. Experience has shown, for example, that our ACTICO® CO2 pulp wash solution can facilitate the transition from bleached to unbleached pulp, helping mills to convert from paper to cardboard. We also offer water treatment support to pulp and paper customers, including cost-effective wastewater treatment solutions like SOLVOCARB® and SOLVOX® oxygen enrichment solutions that keep pollution levels in treated effluent at safe levels while avoiding non-compliance issues. Related areas ADALKA® paper process stabilizer In paper and cardboard industries the stability of pulp and of short-cycle processes reduces the number of disruptions during the process stages, improving machine runnability. The ADALKA Process Stabilizer method increases the stability of pulp and short-cycle processes in a controlled manner and helps obtain conditions that are more stable and more tolerant of disruptions at various process stages. ADALKA is suited for both mechanical and chemical pulp processes. The ADALKA method is patented by Linde. ACU® alkalinity control unit In connection with the ADALKA application the patented ACU® Alkalinity Control Unit is used for the on-site production of pH-adjusted sodium bicarbonate. The automated equipment produces liquid sodium bicarbonate from diluted sodium hydroxide and carbon dioxide. Alkalinity and pH can be adjusted independently according to the process requirements. The buffer solution can then be added to the process to control pH and increase alkalinity at critical points. CODIP® process improver The CODIP ® Process Improver method was developed to mainly serve newsprint paper production, where varying amounts of recycled fibers are used as raw material. The use of carbon dioxide in the paper process helps achieve lower levels of dissolved calcium, increased machine runnability and a more stable pH profile. The patented method was developed in Finland in close cooperation with our customers. GRAFICO® calcium The GRAFICO® Calcium Carbonate Saver is a carbon dioxide application developed and patented by Linde together with the cooperation partner UPM-Kymmene to be used when calcium carbonate is introduced as a filler in the production of paper qualities containing mechanical pulp like newsprint and SC paper. The conditions at the paper machines are often such that calcium carbonate starts to dissolve and papermakers are familiar with problems originated from free calcium in the system. GRAFICO® Calcium Carbonate Saver will help to prevent calcium carbonate from dissolving due to local pH-changes or slightly acidic conditions and create conditions for more stable process. ACTICO® Our environmentally friendly ACTICO ® application offers optimal pH adjustment in the wet end of paper process and reduces the risk of pH shocks. Thanks to its sophisticated automation and carbon dioxide input system, ACTICO can be adjusted to the key process parameters of each paper machine. Improved dewatering The use of carbon dioxide can increase the efficiency of dewatering in paper processes. The patented carbon dioxide application can be used to increase dewatering or improve water cut-off, for example, in the disc filter or wire section. SOLVOX® F back-up cabinet The cabinet is connected permanently to the gas pipeline network via a 22 mm oxygen pipe. The pressure on the network can be read from the pressure gauge. Compressed oxygen can quickly be connected as all the components are ready for use inside the cabinet. The cabinet is designed to be kept outdoors. pH regulation We offer safe carbon dioxide-based pH control systems which are easy to operate and need only low attendance. Carbon dioxide forms a weak acid offering a much more accurate and safe pH control, overdosing is now impossible and the equipment is much more simple and less expensive. In addition the buffer capacity of the treated water will improve significantly.

[ Sustainability Sustainability Through our high-quality solutions, technologies and services we are making our customers more successful and helping to sustain and protect our planet. Ask for advice Sustainable development is rooted into all areas of our business At Linde, we live our mission of making our world more productive. Through our high-quality solutions, technologies and services we are making our customers more successful and helping to sustain and protect our planet. We want to help our customers to improve their environmental performance and reduce their carbon footprint. At the same time, we are committed to minimizing our own environmental resource intensity, including for energy, water and waste. We manage performance through a sustainable development management system with KPIs and targets that are applicable to global operations and our value chain. Measuring environmental impact Mapping of our environmental impacts shows that energy consumption for producing our gases, and emissions from transporting gases to our customers, are the two significant ones. We have defined indicators to measure these impacts and have established targets and improvement programmes. Linde has traditionally been working to develop and deliver innovative technologies and products that protect environment. Examples of environmentally friendly gas applications are: ● Pulp production: oxygen reduces the use of chlorine ● Water treatment : CO2 and oxygen as alternative to chemicals ● Transport cooling: CO2 replaces diesel ● Steel production: furnaces use oxygen instead of air ● Bioenergy: gasification turns forest residues into biofuel ● LNG replaces oil, diesel and liquefied petroleum gas ● Hydrogen has the potential to replace fossil fuels in both industry and transport applications How our gases and solutions contribute to sustainability The Sustainable Development Materiality Assessment (SDMA) defines the priority sustainable development factors for Linde and is the basis of Linde's 10-year sustainable development targets 2018-2028. Clean energy initiatives We believe that issues over long-term energy availability and future climate change will only continue to intensify. Addressing the issues surrounding climate change is one of the highest priorities for Linde around the world. Linde Green – liquefied gases without carbon footprint Linde Green is an opportunity for you as a customer to further reduce your emissions, strengthen your sustainability profile and become an even fairer choice. We take the next step and proudly present Linde Green – liquefied gases without carbon footprint, using renewable energy and fuel in production and for transports, together with climate-compensation. Read more about Linde Green Climate compensated carbon dioxide It is increasingly well-known that using carbonated water at home means buying far fewer disposable plastic bottles, which reduces transportation and saves money. By using CO2 in sparkling water machines you help us to reduce Greenhouse Emissions through climate compensation. Our commitment to the Taking Root project in Nicaragua means we offset more than we emit by planting trees. By offsetting 110% of our emissions by planting trees which bind carbon dioxide from the atmosphere while they grow, we contribute to a positive climate impact. This means the product can be classed as climate-positive. Hydrogen – supporting customers achieve their decarbonization targets To tackle climate change, countries around the world are putting in place ambitious plans to transition to low-carbon sources of energy, with hydrogen at its core. Even though light and small, hydrogen is a powerful energy carrier – one kg of hydrogen carries three times the energy of kerosene. It is a versatile, clean and safe energy carrier that can be used as fuel or as industry feedstock – be it mobility, heavy industry, power buffering or aviation industry. When used in a fuel cell, it produces zero emissions as it only emits water vapor, setting it as a strong contender to decarbonize transportation. Hydrogen could be the most competitive low-carbon solution in more than 20 applications by 2030, including long-haul trucking, shipping, and steel. Linde covers the full spectrum of the hydrogen value chain. We can help customers and industry stakeholders navigate through the complexities of the transition to a zero-carbon economy.

[ Fish farming Fish farming Improving farming efficiency through oxygenation. Ask for advice Innovation center SOLVOX products Downloads Buy here Aquaculture solutions to streamline oxygenation and emergency oxygen supply Aquaculture with its complex onshore and offshore fish farming systems has become the production of choice when it comes to meeting the rapidly rising global demand for fish. Yet the industry is facing a number of challenges in supplying a healthy aquatic environment for best results. Supplementary oxygenation is the key to enhancing a fish farm’s stocking density, to keeping it disease-free and the productivity and overall profitability high. A perfectly balanced oxygen saturation will: ● Improve feed conversion ratio (FCR) for feed cost savings ● A reduction in the FCR from 1.5 to 1.0 can lower production costs by up to 20% ● Raise specific growth rate (SGR) for increased profitability ● Increase fish growth rates even on higher stocking densities ● Better fish healthy and reduced mortality Negative impact of low oxygen levels Saturation levels can drop to 85% with no negative effect on fish well-being, yet once it falls to 75%, the fish reduce their metabolism. Below that level, appetite decreases further, at 60% the fish start to die. Massive mortality results if oxygen saturation keeps falling to reach 40% or even 30%. Did you know? “Dissolved oxygen is by far the most important chemical parameter in aquaculture. Low-dissolved oxygen levels are responsible for more fish kills, either directly or indirectly, than all other problems combined. Like humans, fish require oxygen for respiration. The amount of oxygen consumed by the fish is a function of its size, feeding rate, activity level and temperature. Small fish consume more oxygen than do large fish because of their higher metabolic rate.” (A Fish Farmer’s Guide to understanding water quality, LaDon Swann (Purdue University)) Innovation Centre for Aquaculture and Water Treatment We have worked with aquaculture topics since the early days of this industry and are commited to make a difference to our customers with our inventions - now and in the future. Linde has a Innovation Centre for Aquaculture and Water Treatment in Ålesund, Norway. Specifically, new applications and solutions will be researched and developed at the centre to ensure the future of sustainable aquaculture. We are proud to offer our customers the international exerpertise with a range of services like training, performance measurement and proof-of-concept simulations. Oxygenation in Aquaculture Lack of oxygen can cause massive harm to fish, reducing appetite, compromising growth and well-being, and ultimately resulting in death. Following chart visualises the impact of oxygen saturation on the growth rate, mortality and food conversion ratio (FCR) of salmon for instance. Our offering for the aquaculture industry Our aim is to support the fish farms of all sizes, so that as many people as possible can enjoy the nutritional benefits of the fresah fish without compromising tomorrow’s marine ecosystems. SOLVOX product line SOLVOX® A low-pressure exchangers SOLVOX A® reduces nitrogen and total gas pressure during the water oxygenation process. Therefore, there is normally no need for aeration of raw water. It is available in a variety of options adapted to your individual needs for tanks with a water flow ranging from 75 l/min to 9000 l/min. For the optimal solution, we recommend that you always combine SOLVOX A with SOLVOX stream. SOLVOX® B diffusion hose SOLVOX ® B diffusion hose is a perforated hose used for supplying oxygen to fish tanks and for emergency oxygenation. It is also used for oxygen supply when transporting live fish and the supply of oxygen and CO2 for anaesthetising/sedating the fish. SOLVOX B dissolves oxygen in the water by small bubbles generated through the perforations in the hose. In aquaculture, diffuser hoses are used to stabilise the oxygen levels directly in the fish tank. SOLVOX® C high pressure SOLVOX C cones are designed to increase the concentration of gases in water to a rather high level. In standard operation, the gas transfer efficiency is close to 100%. The operation the cone is simple: as water and gas enter from the top, the water jet forces the water to mix intensively with the oxygen bubbles, thus creating a high specific interface and a high turbulence at a top of the dissolver. SOLVOX® CV recirculation SOLVOX CV is an additional system to boost the oxygenation capacity of SOLVOX C cones, allowing up to 50 % higher oxygen dosing without increasing the water flow rate or energy consumption. SOLVOX CV uses a patented venturi nozzle to re-inject oxygen which is gathered at the top of the cone back into the water feed pipe. The installation can be done without any time consuming shut down. The SOLVOX CV is flanged directly onto the water feed pipe of the cone. By doing so, the water flow rate into the cone can be increased by up to 25% above nominal value, which then gives you an additional 25% increase in oxygen capacity. SOLVOX® CD ceramic diffuser SOLVOX ® CD ceramic diffusers are used to dissolve oxygen and stabilise the levels of oxygen directly in the fish tank. The ceramic diffusers can also be used for emergency oxygenation. SOLVOX CD ceramic diffusers transfers gas into water by generating micro-bubbles at low pressure (maximum pressure 3 bar). SOLVOX CD also provide an aeration/stripping effect of unwanted gases. SOLVOX® CV cone booster SOLVOX® CV is a patented product which is fitted to the water supply to the AGA oxygen cone, SOLVOX C. Inside the SOLVOX CV, specially designed nozzles are connected to a hose from the bleeder valve at the top of the cone. These nozzles create a vacuum that sucks undissolved oxygen from the top of the cone and mixes it in with the flow of water. Both “new” and re-circulated oxygen are supplied to the flow of water via the nozzles in the SOLVOX CV. SOLVOX® F back-up cabinet The cabinet is connected permanently to the gas pipeline network via a 22 mm oxygen pipe. The pressure on the network can be read from the pressure gauge. Compressed oxygen can quickly be connected as all the components are ready for use inside the cabinet. The cabinet is designed to be kept outdoors. SOLVOX® dosing cabinet The dosing cabinet distributes and controls the oxygen from the distribution network to the tank using the customer’s own PLS system. The dosing cabinet is divided into two separate sections, one for normal operation and one for emergencies. The oxygen used for operation is dosed through two rotameters. One of the rotameters feeds oxygen for normal consumption and has to be adjusted gradually according to the oxygen consumption. The other rotameter is fitted in series with a solenoid valve. This valve is controlled by the output saturation in the tank and opens to allow additional oxygen when needed, to keep the oxygen saturation at a constant level in the fish tank. SOLVOX® Mix nozzle unit SOLVOX ® Mix makes it possible to mix water with high oxygen saturation into a main flow without degassing and reduced efficiency. It is especially adapted nozzle unit used in conjunction with installations with SOLVOX ® C (cone). SOLVOX ® Mix is used when pressurized, highly oxygenated water from SOLVOX ® C is to return to a water stream that has a lower pressure.It can be installed at tank level for individual oxygenation, or in the main water supply to the plant to provide basic oxygenation. SOLVOX® Oxystream low-pressure SOLVOX ® OxyStream is a low-pressure oxygenation system for vessels with seawater, brackish water and fresh water. The microbubbles created by SOLVOX Oxystream reduce the concentration of dissolved nitrogen and the total gas pressure of the water. Due to this beneficial effect, external degassing units have become obsolete in many cases. SOLVOX Oxystream achieves maximum effect beginning at about 15‰ salinity and requires a pressure of merely 0.05–0.2 barg to oxygenate the water, strip nitrogen, and create optimal tank hydrodynamics for fish production. The low pressure requirement makes the system very energy-efficient. SOLVOX® streamline SOLVOX® Stream creates a better tank environment and improves the well-being of the fish. It provides good tank hydraulics and even oxygen distribution throughout the water volume. SOLVOX® Stream creates a better tank environment and improves the well-being of the fish. It provides good tank hydraulics and even oxygen distribution throughout the water volume. Rotameter We supply rotameters in various sizes with capacities ranging from 0.4 kg O2/hour to 9.0 kg O2/hour at a pressure of 6 bar (maximum operational pressure 10 bar). At other pressures the capacity is corrected using tables in our datasheet. Handheld Oxygen meter Handy Polaris is simple to use and has a straightforward menu. It takes fast and accurate measurements/logging of O2 and temperature in both salt and fresh water.

[ Cleaning, polishing and grinding Cleaning, polishing and grinding Bringing you the benefits that come from decades of experience and a proven track record. Ask for advice Downloads Buy here Bringing you the benefits that come from decades of experience and a proven track record Our experts are among the most knowledgeable in the world when it comes to gas-enabled applications. Here you will find a wealth of information on the process innovations and application expertise they have brought to Cleaning, Polishing & Grinding. Simply click on the Processes and discover how we can help you meet your quality, efficiency and optimisation targets. Cryocleaning During the printing process most parts of the printing press get contaminated by all kinds of substances like dried ink, paper dust, grease, oil, coatings, varnish, etc. The conventional cleaning methods need aggressive solvents which are toxic, hazardous and can be flammable. An additional problem are long downtimes. Using dry ice cleaning takes away most of those problems and gives substantial benefits to the user. The cleaning agent (dry ice pellets) is very soft like plaster, thus creating no scratches, wear or damages, even on sensitive surfaces. When the cylinders are removed all surfaces are accessible and can be cleaned in a fraction of the time needed before. This gives a dramatic reduction in downtime. Further savings will result from the absence of disposal costs. Did you know? ● To produce crumb rubber, it is necessary to reduce the size of the tire shred or chip. This is accomplished by techniques called cryogenic grinding. ● Cryogenic processing refers to the use of liquid nitrogen (−196°C) to freeze tire chips prior to size reduction. The rubber is immersed in liquid nitrogen to reduce the temperature of the tire chip. The cooled rubber is then ground in an impact-type reduction device. Dry ice cleaning The dry ice cleaning process CRYOCLEAN® increases the output of a printing machine substantially by simultaneously reducing costs for the cleaning. Cryogenic grinding can achieve a very fine level of grind as most hardy materials tend to become brittle when cooled with liquid nitrogen. Waste materials can be separated by exploiting the coldness of liquid nitrogen. Cryogenic grinding can achieve a very fine level of grind as most hardy materials tend to become brittle when cooled with liquid nitrogen. Bleaching Ozone is an attractive alternative to chlorine-containing chemicals as a way to bleach pulp and achieve the necessary level of brightness. It is widely used for both TCF and ECF bleaching. As it is an extremely effective bleaching agent, ozone reduces the volume of other bleaching chemicals required. Grinding Cryogens can be an effective way to reduce the size of materials that cannot be ground under normal conditions. Many materials that are resilient at ambient temperatures become brittle and glass-like under low temperatures. As a result, these materials can be pulverised through impact or shearing. This form of grinding can also be used to create unusual particle shapes or sizes. Various materials are suited to cryogrinding. For instance, materials that are tacky or oily can often be solidified and ground. Products that are heat-sensitive can be processed at a temperature level that allows them to be ground without degrading or melting. In addition, cryogenic impact can debond multicomponent materials such as chrome-plated ABS (plastic). And spices can be ground without loss of volatile oils and flavours, thus preserving and enhancing their quality. Liquid nitrogen The most widely accepted refrigerant for cryogrinding is liquid nitrogen (–196°C). Unlike CO2, liquid nitrogen (LIN) does not go through a solid phase, instead transitioning directly to a gaseous state. LIN can thus be directly injected into a grinding mill. During the solid-to-gas phase change, it produces a powerful cooling effect on the product. Solid carbon dioxide (also known as dry ice) or liquid CO2 can also be used as grinding coolants if temperatures below –78°C are not required. We deliver a tailored, dedicated supply concepts for cryogrinding installations, extending from gas supply and storage systems through supply lines to pressure and temperature control solutions.

They are used not only as petrochemical feedstocks, but also as reactants and oxidative agents. In addition, they support hydrotreating, process intensification, process and quality control, inerting, storage and transport. Gases role from development to implementation We offer a wide range of gas-related solutions spanning state-of-the-art application technologies, end-to-end hardware supply schemes, development tools such as experimental set-ups, calculation programs for process design and software to support safety competence, for instance. Our experts work closely with you in order to develop and optimise the gas application solution best suited to your needs. In addition, we support all stages of the project lifecycle, from trails and design through to implementation and start-up. Would like to learn more about Petrochemical processing and refining Hydrogen in refining + Not only legislation but more extensive processing of residues and higher diesel demand compared with petrol will also increase hydrogen's demand. There are various hydrotreating processes in a refinery. To name a few: ● Hydrodesulphurisation: sulphur compounds are hydrogenated to hydrogen sulphide H2S as feed for Claus plants ● Hydroisomerisation: normal paraffins are converted into iso-paraffins to improve the product properties (e.g. RON) ● Dearomatisation: aromatics are hydrogenated to cyclo paraffins or alkanes ● Hydrocracking: long-chain hydrocarbons are cracked to shorter chains in the gasoline range. Main processes for hydrogen production: ● Steam reforming of methane or other hydrocarbons ● Gasification of organic feedstock to syngas (H2/CO) ● Recovery from gaseous waste streams ● Electrolysis of NaC Process consulting, financing, erection and start-up are all services offered by Linde. We can also provide hydrogen plant operation (over-the-fence-supply), maintenance and repair and emergency supply arrangement to ensure that your business is working at its optimum. Hover on the image to enlarge it Oxygen enrichment in Claus plants + Claus plants in refineries process concentrated hydrogen sulphide (H2S) fractions converting them into elemental sulphur. They can also remove pollutants, particularly by decomposing ammonia. Stricter environmental regulation leads to products with lower sulphur content. As a result Claus plant loadings with hydrogen sulphide and ammonia are increasing and the Claus plant may become a bottleneck. The problem can be overcome by oxygen enrichment of the combustion air. This increases the capacity significantly. A new type of burner ensures excellent mixing of hydrogen sulphide and oxygen enriched air over a wide load range. Benefits of oxygen enrichment in Claus plants: ● Increased Claus plant capacity ● Increased productivity without changing the pressure drop ● More effective treatment of ammonia containing feeds ● Less effort for tail gas purification (reduced nitrogen flow). Oxygen enrichment in FCC units + ​ Fluid catalytic cracking (FCC) converts primarily vacuum gas oil from the crude distillation unit into gasoline blending stocks and fuel oils. FCC breaks down heavier and more complex hydrocarbons into lighter ones. Feed is primarily vacuum gas oil, often mixed with refinery residues. The main products are gas fraction (mainly C3/C4), liquid fraction and coke (solid formation on the catalyst). FCC oxygen enrichment involves the addition of a controlled flow of gaseous oxygen into the combustion air. The additional oxygen in the regenerator results in higher plant efficiency due to: ● Increased plant capacity by up to 35% ● More flexibility in the selection of feedstock, especially to enable use of heavier feedstock with a higher tendency to form coke ● Increased conversion ratio and gasoline yield ● Resolved air blower constraints ● Reduced CO in the regenerator off-gas ● Less abrasion of the catalyst and less erosion of the cyclones due to reduced gas velocity, resulting in less downtimes and repairs In order to help control particulates, sulfur dioxide and NOx emissions from the FCC we offer the LOTOX® technology. LOTOX® is a patented innovation that uses ozone to selectively oxidize insoluble NOx to highly soluble species that can be easily removed in a wet scrubber. The benefits include increased capacity, greater flexibility in the choice of feeds, increased conversion rates and reduced emissions. Partial oxidation + ​ Partial oxidation plants are used to form hydrogen, carbon monoxide, carbon dioxide and water from the residues (liquids, highly viscous hydrocarbons) of the refining process. The products can be used as synthesis gas, fuel gas or feed for hydrogen recovery. With tailored oxygen supply for Partial Oxidation (POX) we can offer you the following benefits: ● Cleaner and better reuse of residues ● Broader economic base of the refinery ● Higher flexibility through a wider range of products ● Handling of refinery feed compositions within a wide range Industrial services for refineries + ​ We offer a vast service portfolio dedicated specifically to the needs of refinery operations. Pressure, temperature, purity and volume requirements can vary significantly across a range of highly specialised applications. Many refinery operators rely on our nitrogen services – sometimes in combination with other gases – to support the following applications: ● Drying and purging: Humidity in pipelines can delay start-up or compromise productivity for days. Purging with large streams of gaseous nitrogen enables pipelines to be dried and heated in a controlled manner, thus accelerating start-up and boosting productivity. We can supply nitrogen at flow rates of up to 25,000 m3/h and at a pressure of up to 700 bar for these applications. ● Inerting and blanketing: We supply inert gases such as nitrogen or carbon dioxide (CO2) to bring oxygen concentrations down to a safe level in environments with the potential for fire and explosions. ● Pipeline pigging: A pig is sometimes pressed through a duct or pipeline that requires cleaning or inspection, especially if it contains viscous material. We supply gaseous nitrogen for this purpose. It is a highly effective, safe and dry pressure medium, supporting a wide range of pressures, temperatures and volume flow rates. ● Leak and pressure testing: We supply a special nitrogen/helium mixture to detect even tiny leaks and leakage rates at operating conditions with pressures of up to 250 bar. The helium acts as an easily detectable tracer gas as it is inert and diffusible. This is an effective, economical solution that enables operators to rapidly remedy defects. We also supply high-pressure nitrogen for testing at pressures of up to 700 bar. ● Reactor cool-down with hot stripping: With our hot stripping and CATCOOL™ processes, refineries can shorten by days the window needed to cool down high-temperature facilities in preparation for inspection. This inert process technology relies on controlled streams of large volumes of cold nitrogen to reduce production downtime. ● Pipe and ground freezing: Cryogenic nitrogen can be used to temporarily seal and freeze pipe sections for installation or repair work. This smart solution eliminates the need to drain and shut down the entire piping system. This method can also be used to freeze the ground for construction work.

[ Modified and controlled atmospheres Modified and controlled atmospheres Bringing you the benefits that come from decades of experience and a proven track record. Ask for advice Areas Downloads Buy here Gas-enabled applications for various industries to optimise their processes Carbonation is the process of adding carbon dioxide to drinks to create fizz, while controlled atmosphere stunning is a technology that creates humane conditions for animals being slaughtered, improving animal welfare and meat quality. Carbon dioxide fertilization enhances the growth of plants in greenhouses, while liquid nitrogen dosing strengthens bottle walls to avoid breakage during transportation. Modified atmosphere packaging uses gas mixtures to extend the shelf life of foodstuffs, without the need for chemicals or freezing. Success through partnership We work closely with food research institutes in many countries, e.g. SIK (Sweden), VTT (Finland), Campden (UK), and have numerous food-processing customers worldwide. To create the best atmosphere for each application, we also collaborate closely with suppliers of packaging materials and machines. Several factors affect the packaging atmosphere: the foodstuff and its properties, microbial activity, hygiene requirements, the pre-packaging delay and temperature. The permeability and other properties of the packaging material, the free gas volume within the package, and the residual oxygen level are also important. Modified Atmosphere Packaging (MAP) Food manufacturers are always looking for ways to extend shelf life. They want to achieve this without altering the physical or chemical properties of foodstuffs, or adding any unnatural ingredients. Modified Atmosphere Packaging (MAP) is the ideal solution. This natural method is rapidly gaining in popularity around the world. It can also complement alternative preservation methods. We have developed a range of application-specific packaging solutions under our MAPAX® brand. Synergizing our vast knowledge of food science, gas mixtures and packaging, MAPAX extends shelf life – the natural way. With MAPAX, you can: ● Increase your sales, by satisfying growing demand for fresh and naturally preserved products ● Extend shelf life without chemicals or freezing ● Increase shelf life in the distribution chain, by days or even weeks ● Retain taste, texture and appearance ● Enhance production and distribution efficiency by cutting costs Related areas Carbonation Carbon dioxide is the most frequently used industrial gas in the beverages industry. It is dissolved in drinks to create the well-known 'fizz' effect. We deliver food-grade carbon dioxide, sourced from both natural wells and industrial facilities. Our carbon dioxide complies with all relevant food guidelines. During carbonation, carbon dioxide is added to the liquid in a carbonator. There, vaporized carbon dioxide is mixed under pressure with temperature-controlled water. Syrup, sweetener and other ingredients are then added, to create the final product. Controlled Atmosphere Stunning (CAS) Consumer interest in animal welfare is rising – as are quality requirements for meat and poultry. Our sophisticated Controlled Atmosphere Stunning (CAS) solutions satisfy the evolving needs of today’s slaughter plants. We can help you to design a safe and reliable system tailored to your individual needs. CAS modifies the atmosphere to create humane euthanasia conditions for animals. This gentle technology provides a less stressful experience, contributing to improved animal welfare, better processing conditions and higher quality meat. CAS provides a less stressful experience for animals and leads to various improvements, including a safer working environment, better plucking results, reduced fecal contamination, easier animal handling, elimination of hemorrhages, bruises and broken bones, reduced meat bruising, and better bleed-out of arteries in the fillet, wing and thigh. These benefits make CAS a preferred method for animal euthanasia, which enhances both animal welfare and meat quality. Carbon dioxide fertilization Normal air has a carbon dioxide concentration of 340 ppm. This is insufficient for producing the best yield. Plants usually require carbon dioxide concentrations of between 600 and 1,000 ppm. Supplementary carbon dioxide is particularly important when using artificial lighting. If the concentration of carbon dioxide is allowed to fall, growth is halted and artificial lighting provides no benefits. When extra carbon dioxide is added to greenhouse air, the tomato, cucumber and lettuce yield improves by up to 25-30%, or even more. Cut flowers and potted plants also benefit from carbon dioxide fertilization. Carbon dioxide not only increases yield, but also produces an earlier harvest and improves plants’ resistance to disease and pests. Carnations can bloom up to one month earlier. Lettuce is ready for harvesting weeks earlier, while tomatoes in tomato sprouts can ripen a week sooner than usual. Carbon dioxide fertilization pays off, as clearly indicated by several studies and practical experience. In greenhouses heated by burning propane, carbon dioxide is obtained as a by-product, but often at the wrong time of day. Carbon dioxide is needed most at midday, when extra heat is seldom needed. The heating system must be able to store this heat, and release it during the cold hours of the day. There is always the risk of incomplete burning, resulting in the formation of NOX, which is very harmful to plants. If a greenhouse heating system cannot store heat, adding pure carbon dioxide to the greenhouse air is usually the best solution. This also helps to avoid the moisture problems produced by burning propane. One kilogram of propane generates 1.6 kilograms of water vapor, which condenses into liquid water. Such water won’t go away by itself. Liquid nitrogen dosing When making drink bottles, manufacturers of non-carbonated beverages (water, juices, teas, etc.) generally rely on PET (polyethylene terephthalate). Over the last 20 years, in line with environmental and cost pressures, plastic bottles have become thinner. However, this has reduced the weight of PET polymers in bottles, resulting in thinner, weaker bottle walls. After filling, bottles must be stacked for transportation to customers. At the bottom of a pallet, weak bottles with thinner walls buckle under the weight of the bottles above. This leads to unsafe conditions and costly product losses. Such a problem can be avoided by pressurizing the bottles. Available in liquid form, nitrogen is the perfect medium for this. When liquid nitrogen vaporizes, it expands to 682 times its liquid volume. In addition, because it is inert, it protects the drink against the drink spoilage and lost revenues that can result from oxidation. We supply the liquid nitrogen (LIN) needed for the LIN dosing systems commonly used in bottling facilities. Such systems add a droplet of liquid nitrogen, which is trapped by immediately capping the bottle. Expanding as it vaporizes, the trapped droplet increases the internal pressure. This ‘rigidifies’ the bottle for stacking. Oxygenation in aquaculture Adequate and stable supply of oxygen is essential for fish welfare, growth and survival. The amount of oxygen required for optimal fish growth is dependent on the fish species, size, feed fish density, activity levels and water temperature. When there is a reduction or stop in oxygen supply, fish will soon start experiencing problems and, in serious cases, die from lack of oxygen. Fish welfare is a constant concern. Maintaining proper oxygen levels is important to the immune system of fish and leads to stable production and economic benefits for the farmer. Carbonation Controlled Atmosphere Stunning (CAS) Carbon dioxide fertilization Liquid nitrogen dosing Oxygenation in aquaculture Carbonation Carbon dioxide is the most frequently used industrial gas in the beverages industry. It is dissolved in drinks to create the well-known 'fizz' effect. We deliver food-grade carbon dioxide, sourced from both natural wells and industrial facilities. Our carbon dioxide complies with all relevant food guidelines. During carbonation, carbon dioxide is added to the liquid in a carbonator. There, vaporized carbon dioxide is mixed under pressure with temperature-controlled water. Syrup, sweetener and other ingredients are then added, to create the final product.

CO2 inhibits microorganisms by reducing pH and penetrating biological membranes. Nitrogen prevents oxidation and package collapse, while oxygen is needed for meat's red color and allows fruits and vegetables to breathe. MAPAX offers tailored solutions for dairy, dry foods & bakery, fish & seafood, fruit & veg, meat, and prepared & catered foods industries. Questions and answers about modified atmosphere packaging Gas + Which gas mixture should I use? It depends on the type of food you produce, the shelf-life you need and the way your product is consumed. For detailed information, refer to the specific MAPAX® flyers and your local Linde application engineer. Tests will probably need to be conducted to decide the optimum mixture. I am just starting out with the MAP system. What equipment do I need? Most systems require a minimum of a regulator, a flowmeter and piping. It is recommended to start with the pre-mixed single cylinders. Contact your local Linde application engineer to see what else might be needed. Is it better to purchase pre-mixed cylinders or to purchase pure gases and mix them on site? This depends on the volume and the type of production at your facility. If the volumes are large or your plant produces various products with different gas requirements, it would be better to mix the right gases on site. Where can I place the cylinders that I am using? Ideally you would want them out of the processing area for quality and hygiene reasons. Please refer to your local regulations. How much pressure do I need to supply to my machine? This depends on the type of machine and the type of product being run. Consult your machine manufacturer as well as your local Linde application engineer. If I use more gas, will using individual cylinders become more expensive? Yes. As your business grows, so will your gas consumption. It is important to consult your Linde representative to work out the best time to switch from cylinders to a bulk tank supply mode. What about safety for the use of gases? We provide safety information and training. Each country has its own safety regulations for the use of gas. These regulations must be followed and integrated into your quality systems. Our specially trained experts will support you here. What precautions should be taken when using gas mixtures with a high oxygen content? Please contact the machine supplier to check whether the machine is suitable for operation with mixtures containing high oxygen levels. The machine has to be specified for high oxygen ratings. What are the functions of different gases? The most important gas is CO2, since it delays the growth of microorganisms by dissolving into the food. N2‚‚ is used to replace O2‚‚ and thereby decrease deterioration. It is also used as a buffer gas. O2‚ is used to keep the red colour of meat and for the respiration of fruit and vegetables. The gases are normally used in mixtures to suit the needs of the specific product. Why should I use food-grade gases? Industrial gases do not meet the legal demands relating to the quality, traceability, labelling and handling of food-grade gases as additives. Food+ How far can I extend the shelf-life of my products by using an MAP system? That depends on many factors such as food product, temperature, hygiene, package and gas mixture. Generally, shelf-life can be increased by a period ranging from days to several weeks. For specific information, see the MAPAX brochure for your particular product. Can I freeze a product that is packed in a modified atmosphere? Yes- but it would be more effective and efficient to first freeze the product and then pack it in a modified atmosphere. Make sure the packaging material is suitable for freezing. Which gas or gas mixture can prevent the greenish colouring on the ham I produce? This greenish colouring is caused by bacteria grown naturally during processing. There is no gas or mixture that can change this afterwards. The meat I pack under MAP loses its colour, but the colour reappears after I open the package. Am I using the right gas mixture? The myoglobin molecule, which is responsible for the colour of meat and meat products, turns different colours with different gases. For recommendations relating to the correct gas mixture, see the MAPAX brochure. The sliced meat product I pack under MAP turns grey. Sometimes only spots on the meat have different colors. Could that be caused by a wrongly filled gas cylinder, or is it caused by the gas mixture in general? The gases and mixtures in our food-grade gases are controlled constantly and the wrong labelling or filling of a cylinder is almost impossible. The grey spots may be caused by a number of factors. To give you just a few ideas: the UV filter of the films could have been changed so that it no longer matches the light exposure, additives could have been changed, or the process could have been altered. Even raw materials like water and meat can vary. Maybe the optimum gas mixture is not being used, or there is an excessively high residual oxygen level in the package or condensed water that can fall down from the lid. Contact your local Linde engineer for tests. Why does drip loss appear in fresh meat in a modified atmosphere? Drip loss is caused by meat handling and processing. Carbon dioxide and oxygen are absorbed and metabolised by the product and microorganisms, creating a partial vacuum inside the container. In fresh meat packaging, this vacuum may be strong enough to actually squeeze water from the meat if insufficient nitrogen is present in the headspace. This can result in drip inside the package. Adding nitrogen should minimise the problem. When I open the food package, I can smell a specific odour. How can we explain this? In most cases when food is properly stored, this is a normal phenomenon. Each product generates its own odour which consists of many volatile compounds that collect in the headspace of the package. Wait a minute after opening. If the smell continues, please check the quality further. Which gas or gas mixture should be used for the ripening of meat? Meat can be successfully ripened in mixtures of CO2‚ and N2. The mixture depends on the type of meat and how it is cut. There are some pale grey, almost white spots on smoked sausages. The sausages are rinsed, cooled in a cryogenic freezer and then packed in MAP. How can I prevent this? There may be a number of reasons for these spots, for example, a local low temperature area could arise during the cooling process that often comes before the slicing. Cryogenic freezing involves very low temperatures that can cause bleaching. Contact your application engineer to check the freezer. Changes in various steps of the process may influence this. Packaging + ​ Does the package labelling have to indicate that the produce is packaged in a modified atmosphere? That depends on regional regulations. For EU countries, if the durability of a food has been extended by being packaged in a modified atmosphere, the packaging must state: Packaged in a protective atmosphere. What headspace (gas volume) is used in the package? That depends on the food product and type of package. The gas volume / product volume ratio lies between 0.5 for sausages and 2 for fish. I get condensation in my package, what’s wrong? The most likely reason is the temperature difference between the product and the storage temperature. We can improve packaged product visibility by using anti-fogging films. The product should always have the lowest possible temperature at the moment of packaging and be kept at the same temperature or lower during storage. The package could also be punctured. Check the residual oxygen. My packages inflate over time. Is the product fermenting? This is nearly always due to the CO2‚ which is generated by the product. This can be caused by too high temperatures (exceeding 4Ā°C) over a certain time. This process cannot be reversed by cooling the product down again. Some products, such as hard cheeses, develop CO2‚ through natural fermentation; this process can sometimes continue after packing and cause an undesirable inflated effect. The package can also be contaminated and develop unwanted gases which cause it to expand. Check immediately with your food lab. Why do MAP packages collapse? This is a normal physical phenomenon that often happens to products with a high water content. CO2‚ is a basic compound in MAP mixtures and dissolves easily in the water and fat phase of a product kept at low temperatures. That’s why the amount of CO2‚ in the head-space decreases and creates a small degree of underpressure inside the package. How do I know that I have the right gas volume and mixture in the package? There are several types of gas analysers on the market. They are easy to use and will give you fairly accurate answers to questions about mixtures and residual O2‚ levels. It is important to establish good routine checks to make sure you do not package a large amount of produce and end up with a less-than-optimum outcome. Your Linde application engineer will assist you by advising on the mixture and equipment best suited to your needs. Why does the residual oxygen in the package increase over time? There are a few reasons why this might happen. There could be a leak in the package or the oxygen barrier may not be high enough. Moreover, air (containing 21% oxygen) could have been trapped within the product during packaging (cakes and breads for example). However, the most common reason is leaks in the sealing. How much residual oxygen is recommended in the package? This depends very much on the product. Consult your local Linde application engineer.

[ Cryogenic preservation Cryogenic preservation Biological samples should be stored at a temperature that is sufficiently below the critical temperature. This is why cells are preserved in special freezers that are cooled using liquid nitrogen. Ask for advice Downloads Buy here Efficient cryopreservation with automatic liquid nitrogen freezers Linde solutions make cryotechnology easier to use. We have designs suitable for many different media and storage temperatures. Linde offers the widest range of products on the market for storage of biological materials and the most advanced vacuum technology in the sector. Our range includes liquid nitrogen deep freezers, liquid nitrogen cans and accessories. Thanks to our broad expertise, we can design and install "Turn key" systems that enable efficient and the most economical use of liquid nitrogen and the best return on your storage investment. Method advantages compared with electrical freezers Liquid nitrogen freezers are reliable, take up less space, save on maintenance costs and are quieter. They can also attain lower temperatures than comparable electrical freezers. Lower temperatures equal greater safety and a longer life for the samples. The devices also do not leak heat into the ambient air. The high-power HE series uses 40% less nitrogen than standard devices with a similar volume. Every freezer is designed for optimum vacuum performance for duration of its use. Freezer structure enables samples to be stored in vapour. The storage temperature, –190°C in the MVE HE (High Efficiency) models, is the lowest on the market. By choosing a liquid nitrogen freezer, you are installing a secure and viable environment free of noise and heat created by mechanical refrigeration system. Did you know? ● Nitrogen is an inert gas, which also eliminates the risk of fire or explosion. ● Liquid nitrogen (LIN) is an extremely effective cooling agent due to the low boiling point of –196 °C. ● Reducing the temperature from +20 °C to –196 °C (ΔT = 216 degrees) requires 0.5–1 liter of liquid nitrogen per kilo of metal. Due to the risk of frost damage, liquid nitrogen must be handled like boiling water. Automated liquid nitrogen freezers Linde represents the world leading manufacturer of vacuum insulated products, Chart-Biomedical. MVE HE Series Automated Liquid Nitrogen Freezers where a temperature of –150 °C or –190 °C is maintained by circulating liquid nitrogen in the lower part of the device. The samples are frozen in vapour phase not by immersing them in liquid nitrogen. The devices are designed to maintain a steady temperature regardless of whether the biological materials are stored in liquid or vapour. One freezer can accommodate 15,600 to 94,500 biological sample vials, and the size of the freezer can be selected according to the customer’s storage requirements. The Liquid Nitrogen Freezers are equipped with a TEC 3000 Control System. TEC 3000 employs a variety of advanced features that enable the controller to monitor the environment inside a freezer with a high level precision. Individual freezers can be equipped with a 230-litre storage tank, with automatic regulation of liquid nitrogen. For larger cryopreservation systems, liquid nitrogen is fed through vacuum-isolated pipelines from an external tank to the freezers. NEW innovative and energy efficient alternative for ultra-low temperature to cryogenic storage Linde together with Chart Bio Medical offers the completely dry sample storage freezer. It will maintain a user-defined temperature anywhere between -50°C and -150°C. The MVE Variō Series significantly reduces the possibility of sample contamination via contact with LN2 while providing the safety margin and consistent temperature profile, even with the lid open, that is associated with LN2 based cryogenic storage. The MVE Variō Series is able to provide all of this with less than 1% of the power consumption and approximately 70% overall operating cost savings when compared to the leading mechanical freezers. Chart MVE1800 Vario What do customers say? “Another thing that is really important to us is sample safety. So in case of lack of electricity we can keep the samples frozen for two weeks after the last liquid nitrogen refill, which wouldn’t be possible with electrical freezers, in which you typically have to evacuate the samples within 24 hours.” Tiina Vesterinen, FIMM Sample Storage Helsinki Laboratory Coordinator HiLIFE, University of Helsinki G Buy products here Nitrogen GENIE® Cylinder Please sign in or register to view prices and order this product.   Add to cart Liquid nitrogen, LIN Please sign in or register to view prices and order this product.   Add to cart LIQUID NITROGEN (CO) DK Please sign in or register to view prices and order this product.   Add to cart Downloads Safety datasheets Product datasheets & brochures Liquid nitrogen safety datasheet Would you like to learn more or ask for advice about cryogenic preservation?

[ Process chemistry Process chemistry ringing you the benefits that come from decades of experience and a proven track record. Ask for advice Engineering expertise in gas-enabled applications Linde engineers are among the most knowledgeable in the world when it comes to gas-enabled applications, which help to improve efficiency, optimisation, and quality across a range of industries. Explore more about the versatility of acetylene in chemical synthesis, benefits of hydrogenation of oil and fat for shelf-life and stability, the use of nitrogen for stirring and mixing liquids, and the use of industrial gases in gas and liquid reactions. Related areas Acetylene for chemical synthesis Acetylene is a versatile tool in today’s specialty and fine chemical industry for its very special and controllable reactivity in a great variety of synthetic applications. The synthetic potential of acetylene paves the way to various Processes in the chemical industry, e. g. for production of perfume components, vitamins, polymer additives, solvents and surface active compounds. Hydrogenation of oil and fat Edible oils can become rancid when exposed to oxygen. The challenge lies in stabilising these oils to increase their shelf life. One way of achieving this is through hydrogenation. This involves chemically converting fatty acids to reduce the number of double bonds. In practical terms, hydrogenated oil is far more shelf-stable and will not go rancid as quickly as untreated oil. It also has a higher melting point, making it ideal for frying and pastry-making. We supply engineered hydrogen solutions to all areas of the edible oil industry. We can design and operate an on-site production plant or simply deliver liquid hydrogen to meet your specific needs. Mixing and storing liquids Nitrogen gas provides a flexible tool for mixing and storing liquids. It offers considerable advantages over conventional stirring methods. No mechanical devices are needed, so there is no reaction with the liquid and no subsequent cleaning is necessary. The method is readily controllable and offers the added advantage that it introduces no new oxygen into the system while at the same time reducing the oxygen content. Gas and liquid reactions Industrial gases like oxygen, hydrogen, carbon monoxide and carbon dioxide are widely used for synthetic processes in the chemical industry. We have designed a modular, multifunctional stirred reactor test plant (CSTR) for the investigation of a large number of homogeneous gas/liquid reactions. The test plant shown in the picture is perfectly suited for verification of preliminary laboratory results as well as scale-up to medium or large sized technical plants. Gaseous oxygen is used in many gas/liquid oxidations, for example, in production of hydroperoxides, the oxidative decarboxylations or oxidation of toluene derivatives. Two oxygen processes could be considered for oxidation processes, oxygen enrichment of oxidation air and total substitution of air by oxygen. The benefits of these processes include increased throughput and selectivity and same conversion rate at lower temperatures. We provide a number of service options, these include; feasibility and profitability studies, test runs with our stirred reactor test plant, process calculations to evaluate the effects, supply and installation of gas mixing units and the installation and start-up of oxygen supply systems. Reactor and process cooling The production of speciality chemicals and active ingredients for the pharmaceutical industry has an increasing demand for synthesis, crystallisation and other unit operations at very low temperatures. With the use of liquid nitrogen (LIN) as a coolant, fluid streams can be chilled to extreme temperatures. Our cryogenic fluid cooling systems are reliable and efficiently chill a process fluid down to –120 °C. Some of the benefits these units provide include: •High flexibility with easy to modify temperature profiles • Comprehensive recording of process parameters • Cost effective nitrogen used for cooling can be reused in the inert gas net and result in keeping operating costs to a minimum. We offer a range of services that include consulting services from initial concept through to final technical specification, demonstrations and test runs on site. We offer a range of standardised products for you to choose from (CUMULUS PX5, PX20, PX50, PX100 with 5, 20, 50, 100 kW cooling capacity). If the range of standard units do not fit your needs we can also provide customised units that are tailor made to your requirements. Heterogenous oxidations Oxidations performed in the heterogeneous gas phase of fixed or fluidized bed reactors are widely used for production of bulk chemicals. Molecular oxygen is the predominant oxidative agent used in these reaction steps. Dependent on the applied process either; air (e. g. for production of maleic or phthalic anhydride), oxygen enriched air (e. g. for production of acrylonitrile) or pure oxygen (e. g. for production of vinylacetate) can be used as a gaseous oxidant. Fluidized bed oxidations are often operated by means of oxidation air, because of its high nitrogen content, it provides an effective fluidizing gas stream for solid particles. The addition of pure oxygen to the oxidation air or the direct oxygen injection into the reactor can reveal considerable benefits to the customer: • Higher plant capacity • Backup of air compression • Relief of waste gas treatment • Enhanced flexibility of plant operation. In addition, the realization of such an oxygen system comes along with remarkable low investment costs. pH regulation Many production plants have problems in keeping the pH value stable in the effluent waste water. In most cases the pH value has to be decreased, and mineral acids are commonly used. But the equipment for this is costly and secondary problems will occur, the use of sulphuric acid will also add sulphates into the water, and hydrochloric acid is highly corrosive for pipes and equipment. Thus you end up with new problems and high operating costs. The handling of such acids is hard to keep safe. Carbon dioxide forms a weak acid offering a much more accurate and safe pH control, overdosing is now impossible and the equipment is much more simple and less expensive. In addition the buffer capacity of the treated water will improve significantly.

[ Welding Welding Supporting all welding techniques with the full selection of welding, shielding and laser gases and mixtures along with reliable supply solutions and robust welding equipment. Ask for advice Areas Buy here Downloads Welding and shielding gases More than 100 different welding methods from MIG and MAG to laser Welding as a joining method has been around for centuries, the use of industrial gases to optimise welding processes dates back to the 40s and 50s. Today, roughly 100 welding methods are used in different industry sectors. Since then the gas based welding processes have emerged to be the predominant group of welding methods. Important gas-shielded welding methods are MIG, MAG, TIG and plasma. Innovations boosted in the 80s and 90s with laser, tandem and laser-hybrid welding. Welding as an essential process in many industries Various techniques are used to melt and fuse metals, steels and alloys. Arc welding, as the most common fusion-based joining method, uses the heat generated by an electric arc struck between an electrode and a workpiece to melt and fuse metal in the joint area. In all welding processes, the shielding and process gases, their exact compositions and their purity levels play a key role in influencing weld quality and productivity. Oxygen, nitrogen, argon and carbon dioxide – the main welding gases Oxygen, nitrogen, argon and carbon dioxide are standard or bulk gases that are used in process and manufacturing industry today. However, in many gas solutions or applications gas mixtures are commonly used. With premium gases like MISON® shielding gas you can increase the quality or your product, the productivity of your labour and the profitability of your business.

Buy here → Welding related areas Gas welding The big advantage of acetylene lies in the reducing effect of the weld­ing flame, which is easy to adjust as well as to control. Gas welding with acetylene is characterized by good gap-bridging capabilities. There is no, or very little, joint preparation required. The problem-free application is particularly useful in out-of-position welding. In pipeline construction, for instance, where other welding methods are usually out of the question or not economical, the oxy-acetylene flame is the welder’s reliable and true friend. Combustion of acetylene with oxygen is characterized by a sharply defined flame cone. Advanced welding processes We have developed a RAPID PROCESSING® concept for high productivity MAG welding, which creates better productivity as a consequence of higher welding speed and/or greater deposition rate. It also decreases less spatter and weld surface slag, better side penetration and smoother weld reinforcements. The technique is eminently suitable for welding non-alloy and low-alloy steels with thicknesses above 1 mm and can also be used on stainless steels. For the best results, unconventional welding parameter settings are used together with an argon-rich MISON® shielding gas, which provides greater productivity and a better working environment. Plasma welding Plasma arc technique is reminiscent of TIG welding, where electric arc burns between a tungsten electrode and the work piece. The most important difference is that the arc in plasma welding is forced through a restriction in the form of a water-cooled nozzle. The greatest advantage of plasma welding is visible on 2 to 8 mm plates with ‘key-hole’ technique, which involves a powerful plasma arc melting a hole through the plate. When the burner is moved forward, material is also melted in front of the hole. This material is forced towards the back of the hole by the arc pressure, where it moves together due to surface tension and solidifies. A homogenous weld is created and complete full-penetration welding is attained. Depending on which gas is used, the shielding gas can have a clear effect on the arc energy. Normally, shielding gas and plasma gas is the same. A root protection gas protects the molten weld pool and the area affected by the heat on the root side of the weld. TIG welding TIG welding method is most often used for welding thin materials (~ 0,3–3 mm). The heat source is an electrical arc that is generated between the work piece and the tungsten electrode. The pool and the electrode are protected by a shielding gas which flows from a gas cup in which the electrode is centrally placed. The shielding gas protects the electrode, the weld pool and the heated material against the damaging effects of air and also affect the properties of the arc (e.g. the energy) and the appearance of the weld, as well as productivity and working environment. An inert gas such as argon, helium or a mixture of the two is most commonly used as shielding gas. Occasionally, hydrogen and/or nitrogen are added in low concentrations. The welder must also be protected against toxic gases and welding fume. MISON® shielding gases protect both the welder and the weld by reducing the emission of damaging ozone MIG brazing The method is very similar to MIG / MAG welding. The biggest difference is the addition material melting point, since the base material does not melt at MIG brazing. Heat input in MIG brazing is considerably less than in MIG / MAG welding, therefore is MIG brazing particularly suitable for welding of zinc coated sheets in such areas as the automotive industry. Argon is often used although small amounts of carbon dioxide and oxygen can be added to improve productivity and properties. In pipeline construction, for instance, where other welding methods are usually out of the question or not economical, the oxy-acetylene flame is the welder’s reliable and true friend. Combustion of acetylene with oxygen is characterized by a sharply defined flame cone. MIG-MAG welding MIG (metal inert gas) and MAG (metal active gas) welding methods are widely used in Western Europe, the United States, and Japan due to their high productivity and ease of mechanization. In MIG/MAG welding, filler metals in the form of solid wire or tubular-cored wire electrodes are melted off continuously in an electric arc generated by a welding power source. The arc and molten weld pool are protected by shielding gases, either inert (e.g., argon, helium) or active (e.g., argon/carbon dioxide, argon/oxygen), which optimize the welding process and properties of the finished product. We offer MISON® shielding gases for optimal welding applications and emphasizes safety measures for welders, including good ventilation and protection against ozone emissions. Safety instructions for working with extreme heat and shielding gases are also provided. In pipeline construction, for instance, where other welding methods are usually out of the question or not economical, the oxy-acetylene flame is the welder’s reliable and true friend. Combustion of acetylene with oxygen is characterized by a sharply defined flame cone. Laser welding Laser welding is gaining popularity in industrial applications. High productivity and quality are contributing factors to the increased use. Examples of applications are welding of automotive components, transmission parts, heat exchangers and tailored blanks. Lasers are also used for welding of medical equipment and lately, also battery components. The CO2 lasers are now often replaced by multiple kilowatt fibre and diode lasers enabling the possibility to guide the laser beam via optical fibres in combination with robots for 3D applications. The laser beam is focused on the metal to be joined causing the material to melt and in some cases vaporize. The welding process is performed as heat conductive or key-hole welding depending on the need for penetration and weld width. Heat conductive welding can be utilized using CO2-, fibre and diode lasers. Deep penetration welding, also known as key-hole welding often demands high laser power (multi kilowatt). Fibre and CO2 lasers are used for this application. Welding gases protect the weld pool, optics, and control plasma formation. Some gas mixtures also interact with the molten metal, improving productivity and weld quality. Our LASERLINE® gases offer optimal solutions for all processes. Gas welding Advanced welding processes Plasma welding TIG welding MIG brazing MIG-MAG welding Laser welding Gas welding – one of the major processes in metal work The big advantage of acetylene lies in the reducing effect of the weld­ing flame, which is easy to adjust as well as to control. Gas welding with acetylene is characterized by good gap-bridging capabilities. There is no, or very little, joint preparation required. The problem-free application is particularly useful in out-of-position welding.

[ FAQ Brand change Why are you changing to Linde? AGA has been a part of Linde since 2000. The merger between Linde and Praxair earlier this year marks a historic highlight when the two companies together form the global market leader in the industrial and medical gas industry with over 80,000 employees and customers in more than 100 countries. As part of the formation of the new Linde, we have decided to change our company name from AGA to Linde in all Scandinavian and Baltic countries from January 2020. The AGA brand will be retained as a product brand for our propane, welding products and carbonated products.Our change of name means no changes to our offer, our contact areas and relationships. In the longer term, however, we are convinced that you as a customer will benefit from Linde's global presence, broad product portfolio, expertise and commitment. We will continue to invest in customized solutions as well as our website and app. What do I as a customer need to do? AGA online shop customers: You don’t need to do anything other than updating your app. AGA will simply change into Linde and you can continue using the service with your AGA username and password. If you go to the webpage aga.dk/shop it will redirect you to the webpage linde-gas.dk/shop. Old app users (propane): Please download the new app with the name Linde shop and create your new profile. The old AGA app should also have a link which takes you to the App Store/Google Play store where you can download the new app. As an old AGA app user, why do I need to download a new app and create a new profile? Since we do not transfer customer data to the new app we ask you to download the new app Linde shop. As mentioned however, if you already have AGA online shop app you don’t need to do anything – this app will be transformed into Linde shop app. What will happen to aga.dk/shop The aga.dk/shop will shut down on 13 of January. You will then be redirected to the new website automatically. When will I get more info about the rebranding? We will continuously inform you about all the upcoming changes through email, push notification and messages in the app and on the website. Exact dates and timelines will also be shared continuously. How do I access my old personal data? You will be able to access and download all your customer information from AGA online shop until 12 of January 2020. After that date, your information will be transferred to Linde online shop automatically. ]

[ Freezing and cooling Freezing and cooling Cryogenic cooling and freezing power to enhance safety, productivity and environmental performance across a wide range of applications. Ask for advice All areas Downloads Buy here Environment friendly alternatives to meet the needs of many industrial production processes Liquid Nitrogen (LIN) and carbon dioxide (CO2) are extremely effective cooling agents due to the low boiling point, which makes them environmentally friendly alternatives to conventional cooling processes, which often involve potentially harmful refrigerants, large quantities of water or dust and fumes. In addition, LIN and CO2 are environmentally sound alternatives to conventional cooling processes, which often involve potentially harmful refrigerants, large quantities of water or dust and fumes. Because they are inert, these gases also eliminate the risk of fire or explosion. Providing rapid freezing and cooling capabilities for many industrial production processes LIN and CO2 are commonly used to ease productivity and enhance quality in concrete mixing, asphalt paving, ground freezing, rubber hose production, glass production, plastic film blowing, grinding, welding and machining. Cryogenic condensation with LIN is also an effective way of purifying waste air and recovering valuable volatile organic compounds (VOC). In the manufacture of aluminium, dross cooling with argon eliminates fumes and dust, while increasing recovery rates. The benefits of LIN in extrusion plants include higher production rates, improved surface finish and increased die lifetime. Cryogenic solutions to preserve food quality Cryogenic solutions are also widely used in the food industry. LIN and CO2 are gentle, effective ways of quickly lowering the temperature of food products to facilitate processing or preserve quality. Dry ice or solid carbon dioxide is a convenient cooling agent for smaller batches, whereas cryogenic, liquid gases are an eco-friendly, flexible and low-noise way of maintaining the precise temperature of entire trucks during transit. LIN and CO2 are commonly used to ease productivity and enhance quality in concrete mixing, ground freezing, rubber hose production, glass production, plastic film blowing, grinding, welding and machining. Cryogenic condensation with LIN is also an effective way of purifying waste air and recovering valuable volatile organic compounds (VOC). Did you know? ● Nitrogen and carbon dioxide are inert gases, which also eliminates the risk of fire or explosion. ● Liquid nitrogen (LIN) and carbon dioxide (CO2) are extremely effective cooling agents due to the low boiling point of LIN (–196 °C) and the low sublimation point of CO2 (–78.5°C). ● At –79°C liquid carbon dioxide converts to solid, which is also known as dry ice, is a flexible, easy-to-use cooling medium. Freezing and cooling areas Food freezing & cooling In the fight against bacteria, one of the most effective weapons is chilling and freezing. Cryogenic freezing also maintains the natural quality of food. Freezing a product leads to the formation of ice crystals. The smaller and more evenly distributed these are, the better the quality and taste of the defrosted product. Quick-freezing at cryogenic temperatures is the only way to ensure that small crystals are created uniformly, both inside and outside the product’s cells. Cryogenic liquid gases also provide an effective, flexible and low-noise way of maintaining the precise temperature of chilled or frozen foodstuffs during transit. Cryogenic condensation Cryogenic condensation with liquid nitrogen (LIN) is a flexible, cost-effective process which can be used in a wide range of applications. We are focused on the following features: • Treatment of highly concentrated exhaust gas flows, • Recovery of valuable components, • Realization of low residual concentrations, • Reuse of vaporized liquid nitrogen as inert gas for inerting and blanketing. We offer a range of standardized products for you to choose from (CIRRUS M50, M150, M500). If the range of standard units do not fit your needs we can also provide customized units that are tailor made to your requirements, all of which we offer installation, start up and liquid nitrogen supply. Dross cooling Once skimmed, thermiting of dross should be prevented as rapidly as possible to preserve its metallic aluminum content which can range from 18% to 80% but cooled safely without polluting the environment. The argon based dross cooling solution Inert Gas Dross Cooler (IGDC) from the STAS company is able to cool all types of dross at any temperature without the use of mechanical moving parts and cooling water, whilst simultaneously snuffing out the thermitting reaction and stopping the generation of fumes and dust. Advantages: • Completely safe, because no water is used in either the cooling of the dross or with the equipment. • Environmentally sound, therefore no emission of dust or fume. • Provides for easy working conditions, therefore is operator friendly. • No moving parts, thus minimizing maintenance costs as well as emitting no noise. • Retains as much of the aluminium alloy present in the dross immediately after skimming (can range from 18-80%) as possible. • Treats all kinds of dross (black and white dross). • Easy to operate, efficiency is independent of the filling level. Ground creezing Under certain conditions, ground freezing with liquid nitrogen is the best solution compared to conventional soil treatment methods. • The set-up of a LIN-freezing plant can be done quickly as large quantities of specialist hardware is available in stock. • The investments for a LIN freezing plant is only a fraction of the amount to install a brine freezing unit. • The temperature of the frozen soil is substantially lower compared to the use of a brine freezing plant, which increases stability. • The low temperature of LIN (-196°C) allows freezing in about 4 to 7 days which is substantial faster than the brine freezing process which easily can take a month. • Environmental friendly process, no hazardous substances, no vibrations and no ground water pollution or extraction. • Automatically working process. Flexible in design of frozen soil. Combination of sealing and static support. • High tolerance to soil humidity (5 – 100%). Frozen soil is 100% watertight, there is no leakage. • The hardness of frozen soil is comparable to concrete. • The solidification of the soil is only temporary. • After shutting down the LIN-supply the frozen soil will melt in a few weeks. Thermal spraying Thermal spraying is the collective expression for several different spraying methods, one of which is flame spraying. When spraying equipment, the additive material, which can be in the form of powder, wire or sticks, is heated to smelting point or a practically smelted condition. The heated material is finely powdered and sprayed by means of a gas flow towards the surface of the piece (the substrate) where it fastens and stiffens. The surface cover can be used as is or worked to the correct dimensions. Flame spraying with the correct additive material can improve the surface’s resistance to corrosion, wear and high temperatures. You can achieve surfaces with high or low friction or alter the surface’s conductivity. Damaged surfaces can be repaired and faulty parts can be corrected to the right dimensions. Rapid cooling Rapid cooling is sometimes required during industrial production processes. Liquid nitrogen (LIN) and carbon dioxide (CO2) are popular cooling agents due to the low boiling point of LIN (-196°C) and the low sublimation point of CO2 (-78,5°C). This enables large-scale heat transfer in a short time period. Advantages of rapid cooling agents: • Unlimited cooling capacity. • Flexibility to reach temperatures as low as -196°C. • Excellent peak-shaving qualities. Cryogenic deflashing In the production of tires for passenger cars some finalizing work has to be done in order to make the tire perfect and attractive. This means rubber flashes need to be removed. Flashes can be found on the surface of a tire on the friction area as well as on the shoulders. Deflashing can be done easily by dipping a rotating tire into liquid nitrogen for cooling the flashes making them brittle enough for scrapers to wipe them off. We offer: Various types of cryogenic deflashing machines including shot blasters and tumblers for a wide range of moulded rubber parts. Development of special devices based on your demands. Deflashing tests on your specific products and provide you with the most suitable machine with consideration paid to all economical and technical aspects. Support with equipment installation and assistance during start-up. Shrink fitting Shrink fitting is a method used in making mechanical joints when axles, bushings and similar are to be fitted inside a part with a hole. The hole is made slightly too small for fitting at even temperature, which means that the outer part needs to be heated or the inner part needs to be cooled. Heating the outer part may take a long time, and in some cases metallurgical reasons may prevent heating altogether. However, cooling the inner part will not affect the property of the metal, and can be achieved much faster. When using liquid nitrogen as a coolant, a temperature difference of up to 200 °C can be achieved. In order to cool the inner part it should be kept in liquid nitrogen (temp. -196 °C), which will make it shrink enough to fit in. The joint becomes durable when the temperatures of the parts are even. Cooling of concrete The solidification of concrete is an exothermic process. As large quantities of heat are released inside the concrete structure, it is important that temperature changes are monitored and influenced, in particular: • In cases with high quality requirements for concrete such as bridges, tunnels and storage tanks. • In cases requiring large volumes of concrete such as dams, large foundations. • In hot climates. Solution cooling with liquid nitrogen has proved to be an effective and cheap method. One particular advantage is that coolant costs are generated only if cooling is really needed. Nitrogen cooling can be applied to cool the aggregates, mixing water or mobile mixer.

[ Certification, analysis and risk assessment Certification, analysis and risk assessment Raising safety levels by documenting gas and gas mixture quality. Ask for advice Gas certificates and analysis The correct safety procedures are essential to protecting gas users against potential sources of harm. Equally important, however, is the need for gas users to understand exactly what they are dealing with. This requires suppliers to be very specific about the quality of the gas products and equipment they provide. To contribute to operator safety, we issue gas certificates for all of our products. These bring operators the peace of mind that comes from knowing that defined quality control processes have been carried out and that all of our gases and gas mixtures have been carefully analysed. Safety assessments An assessment is a careful examination of what could cause harm to people in the workplace. Through knowledge and competence, we can reduce the number of accidents, incidents and injuries. We therefore offer a number of different training courses so that companies and their employees can meet the legal requirements regarding responsibility when handling and distributing gas. In Sweden, Norway and Finland, we also offer complete security analyzes at the customer with regard to the handling and distribution of gas. The analysis sheds light on the customer's operation from a security perspective and results in a detailed report with recommendations on what needs to be fixed. We can also help with documentation to authorities for applications of various kinds. Would like to learn more or ask for advice about application and engineering consultancy?

[ Inertering Inerting Preventing oxidation by controlling or minimizing the level of oxygen in a given space. Ask for advice Areas Downloads Buy here Using inert gases to prevent the oxidation Oxidation is a chemical reaction where a substance, surface or product reacts with atmospheric oxygen in the surrounding air. This can have many undesirable outcomes, including unwanted chemical reactions, the risk of explosion, metal embrittlement and degradation of quality, especially in the case of foodstuffs. The basic principle on inerting entails fully or partially replacing the air around or on top of a product with a dry, inert gas. This forms a protective, safe layer of gas on the substance, preventing oxygen and/or moisture from coming into contact with reactive or absorptive products. In addition, inerting can be used to dispel flammable or poisonous gases. An inert atmosphere is particularly important when storing highly volatile substances or products prone to oxidation. An inert gas does not interact directly with a compound or product. Nitrogen is the most commonly used gas for this purpose, but carbon dioxide or argon is sometimes used. Many industrial processes rely on different inerting methods There are many processes, where it is important to protect against unwelcome reactions, keep moisture away from sensitive substances, control critical reactions and ensure safety during maintenance work.In the food industry inerting is typically used to keep oxygen levels in and around food products low. Aninert or modified atmosphere also stabilizes the product and increases shelf-life. Looking at the chemical industry, reactors, stirring tanks, centrifuges, vacuum filters, grinding and mixing plants, dryers and filling facilities are all often inerted. Mines and silos also rely on inert gases for enhanced safety and fire protection. Many heat treatment furnaces purge flammables, oxygen and water from the furnace for safety reasons and to avoid oxidation of the part being treated. In a more general sense, inerting is also essential for purging pipes and vessels during maintenance and repair work on industrial plants. Nitrogen is the gas most commonly used for inerting Less frequently, carbon dioxide or – in exceptional cases – argon may also be used. Special industries or applications rely on inerting mixtures. In welding shielding gas mixtures combine argon with hydrogen, carbon dioxide, nitrogen and helium. By comparison, modified atmospheres for food generally rely on gas mixtures combining carbon dioxide, nitrogen and oxygen with other gases such as nitrous oxide, argon and hydrogen. Heat treatment furnaces typically deploy nitrogen, argon, hydrogen and other gases. Find out more about the different inerting methods and their range of applications, in the inerting e-book . Inerting areas Blanketing for the food industry Oxidation is a chemical reaction in which atmospheric oxygen in the air surrounding food and drinks attacks the product. This can occur at or below ambient temperatures (i.e. during normal storage of beverages, oils, fruit & vegetables or finished food products). It can also happen at elevated temperatures, such as during processing or deep-fat frying. We deliver food-grade nitrogen and other inert gases that prevent or minimize the effects of oxidation. For example, nitrogen is used to keep oxygen levels in and around the product low. An inert atmosphere stabilizes the product and increases its shelf life. The air in the cavity or headspace around a product can contain moisture and oxygen. High-purity nitrogen is completely dry and inert, preventing it from reacting with the product when used to replace the air in packaging. This is a safe and reliable way of protecting food from the effects of oxidation. We also deliver high-precision valve control systems for filling or emptying food tanks or containers. These valves maintain a constant protective blanket by automatically adjusting the nitrogen content. Blanketing for chemical industry When storing highly volatile substances or substances prone to oxidation, safety and product preservation are of paramount importance. Blanketing with nitrogen is a safe and dependable method for constantly maintaining a protective layer of gas on top of the substance. Humid air in the head space is replaced by high purity, inert and totally dry nitrogen. A precise valve control system ensures that as the tank is filled or emptied, the nitrogen content is automatically compensated to maintain the protective blanket. The result is safety, reliability and protection from degradation through oxidation. For vessels often used in batch processes, characterized by cyclic filling and emptying, we have developed special inert gas sluices which prevent the entry of oxygen effectively. Fluffing Fluffing is a process widely used by manufacturers in the fats and mayonnaise industry. This technique involves using nitrogen to change the texture of the product. Mainly applied to fats in bakery products, fluffing ensures the desired density and eliminates any air. To protect oil and improve oil stability, oxygen should never come into contact with the product during the production process. In line with the worldwide trend towards replacing harsh physical/chemical preservative methods with gentler alternatives, the food industry is increasingly relying on nitrogen to meet the oxidation challenge. Purging for the food industry Oxidation is a chemical reaction, in which atmospheric oxygen in the air surrounding food and drinks attacks the product. This can happen at or below ambient temperatures (i.e. during normal storage of beverages, oils, fruit & vegetables or finished food products). It can also occur at elevated temperatures, such as during processing or deep-fat frying. Through purging, a gas such as nitrogen, carbon dioxide or argon is added to or bubbled through a food or beverage. This displaces atmospheric gases, replacing them with an inert atmosphere. Undesirable substances are eliminated, inhibiting and reducing unwanted chemical reactions with oxygen. As a result, food quality is preserved. We deliver food-grade nitrogen and other inert gases that prevent or minimize the effects of oxidation. For example, nitrogen is used to keep the oxygen levels in and around the product low. An inert atmosphere stabilizes the product and increases its shelf life. Purging for chemical industry The atmosphere within process areas, for example in reactors, can be efficiently and cost-effectively purged of oxygen and moisture at start-up or shut-down with nitrogen (GAN). Filling and rinsing the processor with the dry gas is fully controllable. No pumps are needed so the risk of sparks and ignition or cross contamination is eliminated. What's more, the use of nitrogen ensures 'no reaction' either with the substance previously stored or with what is still to come. Sparging for food industry We deliver food-grade nitrogen and other inert gases that prevent or minimize the effects of oxidation. For example, nitrogen levels can be used to keep oxygen levels in and around the product low. An inert atmosphere stabilizes the product and lengthens its shelf life. Through sparging, a gas such as nitrogen, carbon dioxide or argon is added to or bubbled through a food or beverage. This displaces atmospheric gases, replacing them with an inert atmosphere. Undesirable substances are eliminated, inhibiting and reducing unwanted chemical reactions with oxygen. As a result, food quality is preserved. Sparging for chemical industry In order to protect the oil and improve oil stability, oxygen should never come in contact with the product at any stage of the production process. In line with the worldwide trend towards the replacement of harsh physical/chemical preservative methods with less severe alternatives, the food industry is increasingly relying on nitrogen to resolve the oxidation challenge. Sparging is the process of adding gas as fine bubbles to a process liquid in order to boost the chemical or biological reaction by increasing the available surface area between the two phases. Sparging is fast, effective and can be flexibly introduced to the process environment. Sparging is applied to remove oxygen from a product. Nitrogen is a chemical element. Because it is an inert gas, it does not interact directly with the product. It is used to displace atmospheric air (and thus oxygen) and water vapour to avoid oxidation. Sparging involves injecting a gas into a liquid. Stirring Nitrogen gas provides a flexible tool for mixing and storing liquids. It offers considerable advantages over conventional stirring methods. No mechanical devices are needed, so there is no reaction with the liquid and no subsequent cleaning is necessary. The method is readily controllable and offers the added advantage that it introduces no new oxygen into the system while at the same time reducing the oxygen content. Stripping Stripping is the process of adding gas as fine bubbles to a process liquid in order to absorb a component from the liquid. Nitrogen is used in stripping applications such as removing oxygen from oil or waste water to promote anaerobic activity. This method affords excellent control and does not introduce any other substance into the liquid.

To this end, orders must be placed before 10:00 on the previous working day.

Other special gases are made to order and have a delivery time of 1–2 weeks. Delivery charges include both the transport of cylinders and the return of empty cylinders.

Some of the goods were not delivered, what should I do? Check your order in the Customer Portal as it may be a partial delivery. Otherwise, please contact our customer service with your order number. ​Products & pricing Which solution makes more sense, if I only use gas a few times a year? If you only use gas occasionally, you should bear in mind that you will have to pay a fee for holding the cylinder, whether you use gas or not. Linde recommends that you take out a 1-, 2- and 3-year rental contract, as this is cheaper than a daily contract and you do not have to worry, if you do not use the gas all the time. Is it possible to buy gas cylinders instead of renting? Most industrial, food and medical gas cylinders can be rented, which guarantees that they are checked every time an empty cylinder is returned, and therefore safe Propane cylinders for 5–17 kg of propane (LPG) and UNICYL® 10 litre cylinders are available from us. When a cylinder is empty, we will exchange your existing cylinder for a full cylinder, where you only pay for the gas, not for the rental of the cylinder, but we will not refill your existing empty cylinder, you will take possession of a new filled cylinder. Do gas cylinders have to be returned to the same sales point where they were purchased? No, empty and used gas cylinders can be returned to any Linde sales point, regardless of where they were rented. You can find the nearest Linde agents here. How do I know how much helium I need to blow up balloons? The approximate number of balloons to filled depends on the size and number of balloons. See the attached table for details. Please note that under no circumstances should helium be inhaled, as this can cause a choking hazard which can lead to death. Cylinder size Number of balloons to be filled 5 l 140 (balloon diameter 30 cm) 75 (balloon diameter 25 cm) 40 (balloon diameter 20 cm) 10 l 285 (balloon diameter 30 cm) 145 (balloon diameter 25 cm) 485 (balloon diameter 20 cm) 20 l 590 (balloon diameter 30 cm) 300 (balloon diameter 25 cm) 175 (balloon diameter 20 cm) 50 l 1425 (balloon diameter 30 cm) 730 (balloon diameter 25 cm) 420 (balloon diameter 20 cm) Why are there restrictions on buying certain products and how can they be removed? Some products in Finland require a special authorisation for handling (e.g., refrigerants, medical gases). To order these, you will need to provide us with additional information. For further information on products with restricted ordering please contact Linde Customer Service. If I have received the wrong product with an order, what should I do? If you notice any defects or errors in the delivery, please contact our customer service How can I return defective products/cylinders? Please contact our customer service by providing your order number. What to do if a cylinder goes missing? Please contact our customer service Does Linde fill other suppliers' cylinders?

[ Melting and heating Melting and heating Precision manufacturing processes call for tailored solutions that optimise productivity and efficiencies. Ask for advice All areas Downloads Buy here A variety of techniques to enhance quality and productivity Our experts are among the most knowledgeable in the world when it comes to gas-enabled applications. Here you will find a wealth of information on the process innovations and application expertise. Heating of metal fabrication The main heating processes are following: Preheating – certain materials must be preheated before welding to avoid hardening cracks. After welding, stress relief heat treatment may be necessary in order to reduce welding stress. Flame straightening – this technique is employed to change or restore the shape of parts that have been distorted. When a defined section is heated beyond its yield limit and the surrounding prevent expansion, plastic deformation will occur. Once cooled, the material will shrink in size. A skilled operator can heat isolated spots to straighten the deformation. Melting – this involves soldering, brazing and fusing of sprayed coatings as well as flame welding. Forming – the part to be formed is heated locally. An external force is then applied to form the part. For example, necking out pipe branch stubs. Shrink fitting – to achieve a change in size used for shrink fitting to securely fit shafts/bearings. Liquid nitrogen can be used for cooling (shrinking) and an oxy-acetylene flame for heating (expanding). Stress relief heat treatment – this may be necessary after welding. Metal structure changes – this involves flame-hardening. Heating furnaces Our Oxyfuel-based solutions are designed to help you achieve the same process results with less fuel consumption, reduced harmful emissions and even increased process capacity. For existing furnaces with unchanged staffing, REBOX® oxyfuel offers efficient solutions providing increased production capacity and flexibility, decreased fuel costs and lowered emissions of carbon dioxide, NOx and SOx. REBOX has also been successfully applied in new furnaces. REBOX offers more capacity with less emission to any new or existing furnace by: Throughput (t/h) increased up to 50%; Fuel savings up to 50% Corresponding to a 50% reduction of CO2. Aluminium melting Low-temperature oxyfuel combustion technology is uniquely designed for the challenges that exists within the aluminium industry to boost capacity, with uniform furnace temperatures to avoid hot spots, reduce fuel consumption, improve yields and reduce emissions. The combustion occurs under a diluted oxygen concentration by mixing the furnace gases into the combustion zone. This slows down the oxyfuel combustion reactions and results in lower flame temperatures, comparable to those of airfuel technology, which are below the point at which thermal NOx is created. The mixing of furnace gases into the flame also disperses the energy throughout the entire furnace for uniform heating and more efficient melting. The dispersed flame contains the same amount of energy but with a much more effective distribution. The overall result is more homogenous heating and melting, enabling not only a higher power input and thus higher melt rates, but also reduced formation of dross and NOx emissions. Ladle heating Flameless oxyfuel combustion technology is uniquely designed to boost capacity, reduce fuel consumption, improve temperature uniformity and lowering emissions. The combustion occurs under a diluted oxygen concentration as flue gases are mixed into the combustion zone. This slows down the oxyfuel combustion reactions and results in lower flame temperatures, which are below the point at which thermal NOx is created. The overall result is a more homogenous heating, a further decreased fuel consumption, and reduced emission of NOX emissions. Customer benefits: Up to 55% reduction of fuel consumption and CO2 emissions 25% shorter heating cycle for ladles. Flameless oxyfuel promotes a more uniform heating to further extend refractory lining life. Flameless oxyfuel effectively lowers NOx emissions. Compact, simple and powerful oxyfuel installation, easy to fit on any vessel. A hotter ladle allows for lower metal tapping temperature saving energy, refractory lining and reducing number of rejections (returns due to too low metal temperature). A faster heating, which could reduce the number of ladles in circulation. Hotter and uniformly heated vessel for improved cast product quality. Glass forming and processing Polishing and fusing enhance the surface quality of glass. Flames from our special burners impinge the glass directly to remelt a thin surface layer. Polishing can be used to eliminate or reduce the need for etching, thus reducing the environmental impact and paving the way for a cleaner, safer working environment. Benefits of pre-mixed burners Pre-mixed burners are more efficient than post-mixed burners. In addition, technologies based on hydrogen/oxygen are more efficient than those using natural gas/oxygen or propane/oxygen. Our pre-mixed technology with oxygen and hydrogen is the solution of choice for high-end processes where speed, quality and efficiency are critical. Glass melting The variety of ways to increase combustion efficiency when melting glass include oxygen enrichment, oxygen lancing, oxyfuel boosting, all oxyfuel. Using oxygen instead of air in combustion processes eliminates nitrogen and increases flame temperatures. Oxyfuel solutions also raise the concentration of CO2 and H2O in the vicinity of the flame. And since these gases are mainly responsible for thermal radiation, they make gas jets more efficient. Deployed correctly, burners help control heat input more accurately, improve glass circulation and enhance batch melting. We offer a range of burners tailored to individual applications.

Gray and blue hydrogen are important steppingstones on the path to green hydrogen as they will allow for the necessary frameworks and infrastructures to be developed while green hydrogen production reaches the necessary scale. Green hydrogen is environmentally friendly and generates no carbon dioxide emissions. We can produce hydrogen from a range of feedstocks and natural resources. Using processes like steam reforming, we generate gray hydrogen from natural gas, liquefied petroleum gas (LPG) or naphtha, which is the most common, and cheapest, hydrogen production process today. This process can be converted into blue hydrogen production by adding carbon capture and storage technologies. And, to generate green hydrogen we use electrolysis technology with renewable energy as feedstock. An alternative production method is steam methane reforming with biomass as feedstock.

[ Cutting Cutting There are various ways of separating materials. They include mechanical methods such as sheering and thermal methods such as oxyfuel, plasma and laser cutting. Ask for advice All areas Downloads Buy here Different methods for cutting materials In the case of oxyfuel, plasma and laser cutting, thermal energy is used to heat materials up to ignition, melting or evaporation temperatures. Flame cutting and laser cutting with oxygen use the exothermic energy of the oxygen reaction in the process. Flame and laser beam heat material only until ignition temperature is reached. In plasma cutting and laser cutting with nitrogen, the material is heated up to melting temperatures and the cutting gas blows out the melt. The choice of cutting gas needs to be adapted to application for best performance. Cutting methods Flame cutting Flame cutting is a combustion process. It is not the heating flame itself that does the actual cutting but an oxygen jet, which burns the material during the heat formation and transports the combustion products (slag) away from the cut. Before cutting can begin, the steel has to be heated to ignition temperature by means of a gas flame. The choice of fuel gas affects cut quality and the time used for preheating. Flame cutting can be used for cutting mild and low-alloyed steel in thicknesses up to more than 1000 mm. The cut quality also depends on the surface of the work piece and can be affected by different types of shop-primer. The use of several burners for straight cutting, phase cutting and joint preparation is an example of the versatility of the cutting process. The process is also easy to mechanize. Laser cutting Laser is best suited for high precision cutting of thin pieces. The cut quality is so high that the pieces can be used directly or sent to further processing without the need for post-cut finishing. The focused laser beam is so powerful that it directly melts and vaporizes the material to be cut. Laser can also cut many other materials besides metals, such as plastics, wood etc. The application determines which of the gases, oxygen or nitrogen, is better suited for the task. Oxygen reacts exothermically (generates heat) with the material, which enables faster cutting speed than with nitrogen. As a result, oxygen is the most important cutting gas for cutting mild and low-alloy steels. Meanwhile it is not well suited for cutting stainless steel due to the cut surface losing its corrosion resistance. Aluminium surfaces cut with oxygen are uneven and burred. To get a clean, oxide-free cut surface, nitrogen must be used when cutting these materials. Our dedicated LASERLINE® gases and gas supply systems help to ensure that your cutting activities continue to be high-tech and economical from start to finish. Plasma cutting Plasma cutting is a melt-cutting method, where the energy of the hot plasma arc is used for blowing away molten material. Plasma is a state of matter where the gas that is ionized, which means that it consists of positive ions and electrons causing the media to be electrically conductive. Plasma melts the material locally and the melted material is removed from the cut by means of the gas jet. For example, mild steel is often cut with oxygen or nitrogen as plasma gas while stainless steel is often cut with an argon (or nitrogen) based gas including hydrogen as a reducing media. Flame cutting Laser cutting Plasma cutting Flame cutting Flame cutting is a combustion process. It is not the heating flame itself that does the actual cutting but an oxygen jet, which burns the material during the heat formation and transports the combustion products (slag) away from the cut. Before cutting can begin, the steel has to be heated to ignition temperature by means of a gas flame. The choice of fuel gas affects cut quality and the time used for preheating. Flame cutting can be used for cutting mild and low-alloyed steel in thicknesses up to more than 1000 mm. The cut quality also depends on the surface of the work piece and can be affected by different types of shop-primer. The use of several burners for straight cutting, phase cutting and joint preparation is an example of the versatility of the cutting process. The process is also easy to mechanize. High purity laser gases for protecting the beam A safe, reliable and efficient gas supply is one of the most important elements to consider when investing in a new laser machine or optimizing your existing laser operations. Linde will effectively support you through that process. Resonator gases are used in gas lasers to generate laser light. The gas mixture for a CO2 laser contains helium, nitrogen and carbon dioxide. Other additives are used for certain laser types e.g. oxygen, hydrogen, xenon and carbon monoxide. Gas mixtures for excimer lasers often consist of halogens, noble gases (krypton, xenon or argon) and buffer gases (helium or neon). A modern carbon dioxide laser requires laser gases of high purity. Excessive amounts of impurities may affect the output of the laser. The lifetime of the optical components may also be affected. In this context, water vapour and hydrocarbons are the most critical impurities. What do our customers say? “I am very pleased with Linde as supplier of laser gases and services to our company. I especially appreciate the technical support. Quick response times and dedicated, competent Linde technicians are of great value for us.” Richard Jorvén, MD and Owner.

[ Moulding, foaming, forming and extrusion Moulding, foaming, forming and extrusion Bringing you the benefits that come from decades of experience and a proven track record. Ask for advice Areas Downloads Buy here Exploring the full potential of industrial gases to optimise plastics and rubber processing The plastics industry faces a number of environmental, productivity and quality challenges at various steps in the process chain. Industrial gases can play an instrumental role in optimising many of these processes. We have developed a range of gas-enabled process technologies specifically for the plastics industry. Reaching beyond innovative hardware and gas delivery concepts, we also support our customers with leading-edge process consulting for maximum quality, capacity and profitability gains. Related areas Tire vulcanization Using nitrogen to reduce costs and increase productivity. Nitrogen can be used as a very effective replacement for steam in the vulcanization of tires and hoses. This proven, environmentally friendly solution offers the following benefits: • Reduced energy costs • Increased productivity through reduced cycle times • Improved quality and longer tire bladder lifetimes • Reduced maintenance costs due to reduction in pipeline corrosion Linde fully supports your conversion to nitrogen with on site assistance during testing and products trials, we also provide support to select the optimum supply system to meet your needs, and work with you to optimize your system to achieve the maximum benefits. Extrusion foaming Extrusion for foaming and cooling. Use carbon dioxide or nitrogen as physical blowing agents in your extrusion foaming. These inert gases offer a lot of advantages as they are environmentally friendly, inexpensive and inflammable. The use of physical blowing agents, carbon dioxide or nitrogen in extrusion foaming processes gives lighter parts and lower consumption of raw material. The physical blowing agent is first injected with great accuracy into the polymer melt by means of a metering unit and then dissolved in the polymer. The pressure is maintained throughout the extruder. A rapid pressure drop rate creates a homogenous cell structure of foamed polymer resulting in a light, strong product that can be used in a wide range of applications by the packaging, automotive, electric and manufacturing industries. Typical products foamed with carbon dioxide are extruded polystyrene (XPS) insulation boards or extruded polystyrene foam sheets for food packaging. Nitrogen is mainly used in production of polyethylene cable insulation. Extrusion inner cooling The use of liquid carbon dioxide in extrusion inner cooling of profiles and pipes increases extrusion capacity while investment costs are very low. The homogenous cooling of the profile decreases warp and the product quality is improved. There are no residues and no moisture inside the profile. This patented technology is especially recommended for parts with thick walls and extrusion lines with limited cooling sections. If you want to increase the output of your extrusion line use carbon dioxide for inner cooling of hollow profiles or pipes. Injection moulding You can achieve higher efficiency and reduced cycle time by using carbon dioxide or nitrogen in gas injection moulding, micro-cellular foaming or cooling technologies. These gas technologies developed for injection moulding processes are patented. Gas injection moulding, GIM In gas injection moulding, GIM, nitrogen is injected under high pressure in the melted polymer in order to create hollow part. GIM offers increased component design flexibility, part weight reduction and cost savings on resign. Use nitrogen under high pressure in your injection moulding process and you will benefit with improved product quality, part weight reduction, cost savings on resign and reduced cycle time. PLASTINUM® Injection Moulding Inerting is an innovative method to enhance the quality and productivity of injection moulding processes in general and gas injection moulding in particular. Our supply concept covers: •Optimal supply with cylinders or cylinder bundles for tests or at start phase of production •Vacuum insulated tanks for liquid nitrogen or carbon dioxide, mainly for full-scale production •Nitrogen generators on site with membrane or PSA plants Carbon dioxide spot cooling Micro-cellular foaming developed for injection moulding uses carbon dioxide or nitrogen as foaming agents. The product weight is reduced and savings on material are obvious. Besides that the clamping force is lower. In injection moulding, uniform temperature distribution on the cavity surface is crucial for high quality and short cycle times. Especially the conventional water cooling of long, thin cores or other difficult-to-access areas faces severe problems, such as excessive heat, clogged runners, or unwanted pressure losses. The results are removal problems, surface defects, warpage, and long cooling times. Temperature control with liquid carbon dioxide efficiently cools the hot spots in the mould, such as very thin parts, small cores or areas with material accumulations, resulting in enormous cooling time reductions and quality improvements. To do so, liquid carbon dioxide flows under high pressure (approx. 60 bar) through small, flexible capillary tubes (outer diameter 1.6 mm) exactly to the point of use where the cooling is required. The carbon dioxide expansion creates a snow and gas mixture with a temperature of –79 °C. After removing heat from the mould, the now gaseous carbon dioxide leaves the cavity through exhaust channels. Mould cooling with carbon dioxide is used to improve quality and reduce cycle time. SOLVOX® F back-up cabinet The cabinet is connected permanently to the gas pipeline network via a 22 mm oxygen pipe. The pressure on the network can be read from the pressure gauge. Compressed oxygen can quickly be connected as all the components are ready for use inside the cabinet. The cabinet is designed to be kept outdoors. Blow moulding To increase productivity and enhance quality, liquid carbon dioxide or liquid nitrogen can be used instead of cooled air in the blow moulding processes of the plastic industry. Benefits of blow moulding: • Increased productivity through more effective utilization of machines • Improved dimensional stability of the moulded parts • Shortened time cycle • Enhanced esthetical qualities of the product • This method is most suitable for the cooling of thick-walled parts with a long cycle and cooling times Tire vulcanization Extrusion foaming Extrusion inner cooling Injection moulding Gas injection moulding, GIM Carbon dioxide spot cooling Blow moulding Tire vulcanization Using nitrogen to reduce costs and increase productivity. Nitrogen can be used as a very effective replacement for steam in the vulcanization of tires and hoses.

[ Welding related processes Welding related processes Differentiated depending techniques, gases and working temperatures. Ask for advice All areas Downloads Buy here Different processes to achieve the best welding result We provide end-to-end solutions to meet all of your individual welding related process needs from brazing in high temperatures to flame spraying to improve the surface’s resistance to corrosion. Related areas Brazing and soldering In both brazing and soldering, the solder is added in between the surfaces to be joined through capillary action. In soldering the working temperature is below 450 °C and it is suited for welding copper and copper alloys, zinc, steel aluminium and aluminium alloys. In brazing, the working temperature is between 450 °C–1000 °C and well-suited for most metals. Brazing is used, for example, for welding copper pipes in the production of bathroom fixtures and for fastening pieces of hard metal to saw blades and drill bits. Soldering provides joints of high quality and high surface finish. Soldering does not involve the same high working temperature as welding, which gives rise to less problems with deformations. Flame heating Flame heating means local heating preparatory to hot forming, e.g. bending of pipes, necking of distributors, dishing of vessel bottoms, or for preheating and reheating in welding and flame cutting. There is a direct relationship between flow velocity and flame propagation rate. The higher the flame propagation rate, the higher the flow velocity can be set. The higher the flow velocity, the higher the gas volume combusted per unit of time. The more gas is combused, the higher the concentration of heat released. Gouging Gouging is used in joint preparation and for removal of defective welds. It is similar to gas cutting. The oxy-fuel gas flame heats up the piece to be worked to ignition temperature and the cutting oxygen jet combusts and carries away the molten metal. In gas cutting the cutting oxygen beam is directed at a right-angle towards the work-piece, while in gouging the oxygen beam is almost parallel with the surface of the piece to be worked. An oxy-fuel gas flame can also be used in flame cleaning to clean surfaces from rust, mill scale, paint, grease and dust. In gouging and flame cleaning various fuel gases are used together with oxygen. By using ODOROX® (odorized oxygen) you can minimize the risk of fire and explosion which is always associated with fuel gases. The smell warns of gas leaks in good time. Thermal spraying When spraying, the additive material, which can be in the form of powder, wire or sticks, is heated to melting temperature or a practically melted condition. The heated material is finely distributed and sprayed by means of a gas flow towards the surface of the piece (the substrate) where it fastens and solidifies. The sprayed surface can be used as is or worked to the correct dimensions. It is often a component’s surface that limits the life-time since it is exposed to wear, corrosion and/or high temperature. Flame spraying with the correct additive material can improve the surface’s resistance to corrosion, wear and high temperatures. You can achieve surfaces with high or low friction or alter the surface’s conductivity. Flame straightening Welding and cutting create tensions in the material that can lead to undesirable deformations. If those deformations cannot be accepted, the piece must be straightened. Flame straightening is often a suitable method, carried out by rapidly heating the construction or piece locally. When the material cools down it will shrink, correcting the deformation. The method is suitable for steel, nickel, copper, brass, aluminium and titanium. Even though different fuel gases can be used for heating, acetylene is the best choice since it provides the hottest and most concentrated flame as well as the fastest heating. By using ODOROX® (odorized oxygen) you can minimize the risk of fire and explosion which is associated with fuel gases. Flame cleaning Flame cleaning with acetylene is used wherever clean sheet metal surfaces are required for further processing. Flame cleaned surfaces ensure excellent adhesion of paint and coatings. Thereby, cor­rosion resistance is also improved. Flame cleaning procedures are also used for thermal treatment of concrete and natural stone surfaces. Also old paint and coatings, oil contamination, and abraded rubber can be removed in an environmentally friendly way. The concrete thus exposed gives optimal adhesion for synthetic resin coatings. Brazing and soldering Flame heating Gouging Thermal spraying Flame straightening Flame cleaning Brazing and soldering In both brazing and soldering, the solder is added in between the surfaces to be joined through capillary action. In soldering the working temperature is below 450 °C and it is suited for welding copper and copper alloys, zinc, steel aluminium and aluminium alloys.
