Environmentally friendly recycling of refrigerators

The proper disposal of old and faulty refrigerators and freezers is very important for environmental protection. Above all, it is necessary to prevent harmful substances such as compressor oil, mercury or chlorofluorocarbons (CFCs) from getting into the soil, groundwater or air.

Harnessing cooling energy

The beverage industry is increasingly using gases that are delivered in liquid form and vaporised for a specific application. The EcoVap process makes the cooling energy that is released available for other applications. This allows energy to be saved and the carbon footprint to be reduced in cooling units, for example.

Harder through cooling

“Microstructure” and “crystal structure” are among the most frequently used words when metallurgists talk about steel. Besides the chemical composition of an alloy, the main factor in determining the properties of steel is the spatial arrangement of its atoms.

Messer explains modified atmosphere packaging

Modified atmosphere packaging has established itself as one of the most effective and sustainable methods of extending the shelf life of foodstuffs. Messer offers exactly the right gases for this purpose.

Gases for pneumatic tyres – safer and more economical

Ever since the Michelin brothers first fitted pneumatic rubber tyres to a motor car in 1895, it has become impossible to imagine our motoring existence without them. They provide comfort and safety when driving. In motor racing, they are sometimes the deciding factor for victory or defeat. Improvements to aerodynamics may perhaps save a tenth of a second per lap in Formula 1; the correct tyres can change everything. Aircraft and Formula 1 pilots fill their tyres with a special gas rather than air, and so too do demanding drivers. Gases also play an important role in the manufacture of tyres.

Strong protection for fine wines

Wine growers and wine connoisseurs know that the quality of a wine is created “on the vine”. It is only the grapes and what has accumulated inside them during the ripening process that can subsequently tickle the taste buds of wine lovers. This includes around a thousand volatile compounds that have so far been identified by oenology – the science and study of wine. The foremost task of vintners is to bottle as many of these flavour-giving substances as possible. In doing so, they have to contend with some strong adversaries though: bacteria, fungi, heat and oxygen all pose a threat to the sensitive flavour compounds. In modern winemaking, gases are one of the methods of choice for keeping these adversaries in check.

Freshness that goes down well

Having a quick bite to eat no longer means a sandwich and an apple, nor necessarily a burger or curried sausage. A diverse fast-food industry caters to the need for quick meals. The convenience food that is now also offered by supermarkets and convenience stores covers a wide range of ready small meals for instant consumption or quick preparation. The delicious range that is available covers gourmet sandwiches, organic ravioli and a variety of mixed salads. And because fresh products are used, the food is also very healthy when combined in a balanced way. An unbroken cold chain is needed to ensure that the perishable products retain their quality between preparation and consumption. This is a technical and logistical challenge given the variety of products and customers.

Gases and beverages

There are important processes in the beverage industry which are only possible with gases. Carbonation of soft drinks and beer has been the most important application for over a hundred years. Gases also help to protect product quality, particularly during the inertisation of tanks as well as filling operations. Without nitrogen for pressure stabilisation, the storage and transport of non-carbonated beverages would be more complex and expensive. For some years now, there has also been an increasing use of gases in winemaking, where they facilitate the production of top-quality wines.

Efficient Cooling for Reliable Processing

The laws of physics give gas cooling some distinct advantages. The gas transports the cold quickly to the desired location and then evaporates without leaving any residue. Cryogenic gases offer the optimal solution for mixer cooling in the food industry, not least with regard to product quality. In addition to this, their use can contribute to the design of an especially efficient process. At the industrial gas specialist Messer, Variomix is the name used to describe all processes in which foodstuffs in mixers, grinders and shredders are cooled by the addition of gases.

Hardness and dimensional stability thank cooling energy

To obtain wear-resistant and dimensionally stable steel components, the retained austenite in the material must be transformed into martensite as completely as possible after hardening. This step has a crucial bearing on the steel quality, for instance when it comes to the ability of tool steel to retain an edge or the dimensional accuracy of very fine contours in casting moulds. The transformation is usually achieved with repeated heating and cooling over a long period of time. Cryogenic treatment offers a time- and energy-saving alternative, which also enables a more comprehensive transformation of the retained austenite.

Carbon dioxide – a gas that can also relieve the environment

Of all things, carbon dioxide (CO2) – one of the main causes of global climate change – seems to be a true revelation when it comes to the more efficient use of resources. The reason for this surprising development is the possibility to utilize oilfields more efficiently and to their full potential with carbon dioxide.

Gases – the invisible secret of laser material processing

Growing pressures for productivity, economy and quality demand new solutions and technologies in the area of welding and cutting. One result of these constantly growing demands is laser technology. With its cutting gases Nitrocut® and Oxycut® and the product series MeGaLas® ,Messer Gases for Laser material processing, Messer, the largest privately managed industrial gases specialist, provides all the gases and gas mixes required for laser material processing.

Garden hoses are turned into garden hoses

PVC – polyvinyl chloride – is one of the most widely used plastics in Europe. If plasticisers are added to the PVC, it can be used for floor coverings, dashboards or seals. However, landfilling or incineration of PVC waste is problematic for various reasons, and soft PVC reutilisation is also challenging.

Moonlight for vampires – and other remarkable gas applications

Powder production with the VarioSol process, medical gases for hospitals and doctors’ practices, cleaning with dry ice, or the Siber process for an unbroken cold chain during food transportation – Messer supplies gases for a wide and diverse range of applications, some of which are quite unusualor just plain strange. on air takes a look at the most remarkable applications.

Cryogenic treatment for hard substances

Above a certain temperature, concrete becomes more difficult to process. To prevent this, concrete and its additives can be cooled by means of cryogenic gases. Messer supplies the construction industry with the necessary equipment and know-how.

Messer steps on the gas for the car industry

Messer supplies gases for a host of applications technologies within the automotive industry, ranging from the chassis and the engine right through to the electronics. Expertise and experience garnered over more than a century have made Messer one of the leading experts in this field.

Gas – the good spirit of wine

Wines with a fresh, fruity character are in high demand these days. Essential to their production are quick and careful wine preparation, must purification, controlled fermentation and oxidation, as well as thorough hygiene. One noticeable development in the wine technology of today is the growing interest in gas applications.

Welding and cutting – united with the future

Actively shaping the rapid development in welding and cutting requires more than a high-quality, customised product range. Consequently, Messer maintains particularly close contact to customers in Europe and China and to distinguished research institutes in order to continually develop its processes.

More than just the air that you breathe – medical gases

Medical gases have become indispensable in modern-day medicine. Whether as breathing gas or as anaesthetic, in medicinal baths or in diagnostics, they are applied widely. However, hospitals, doctors and patients require not only gases, but also the necessary hardware to use them.

Tough, ice cold and with real pressure – cleaning with dry ice

Dry ice blasting is a relatively new process which gets rid of even stubborn dirt residues in a particularly gentle and above all environmentally friendly way. Offering speed, flexibility and mobility in its use, dry ice blasting increasingly represents a cost-saving alternative to other cleaning processes. Plus it has even more advantages for its users.
