AGA online shop


AGA supplies a wide variety of industrial gases for various industries, including dry ice, shielding gases, food gases, laser gases, liquid gases, refrigerant and fuel gases. We offer different gas cylinders, such as aluminium, steel and GENIE cylinders

Shielding Gases

In our shielding gas program, gases are developed for most welding methods and materials in both our standard and premium program, MISON®.

Root Protection Gases

Gas for root protection or leak detection, like Formier®.

Pure gases

Pure gases used in a variety of applications, like Argon, Nitrogen, Oxygen and CO2.

Other Gases

Here you find Balloonhelium, breathing oxygen and air.

Fuel Gases

A number of fuel gases are used for industrial applications, in combination with oxygen or air: e.g. Acetylene and Hydrogen.

Laser Gases

Special gases for Laser cutting and welding. Pure gases and mixes.


AGA offers a complete refrigerant program for the refrigeration industry, covering both natural refrigerants, and HFC and HFO. All of our refrigerant cylinders are individually marked for traceability and may be combined with ACCURA® cylinder services

Dry Ice

Aga offers dry ice as grains or pellets, with a grain diameter of 10 mm and length 20 mm and also dry ice blocks, with each block wrapped in a protective sheet of paper. Buy dry ice online

Food Gases

BIOGON® is a product series of food grade gases. We supply food grade carbon dioxide, nitrogen, and oxygen and mixes for modified atmosphere. Our food grade gases conform to “food grade” regulations, e.g. the EC directive 96/77/EC

Liquid Gas

Liquid Nitrogen in cryo containers

Industrial gas

The air around us is a mixture of many different gases, but just three elements – nitrogen, oxygen and argon - form nearly all of it. Air is the raw material for producing gases. After the gases are extracted, what remains is returned to the atmosphere. AGA’s most important products are oxygen, nitrogen and argon. Gas can be compressed. Examples of gases are oxygen at room temperature (approximately 20 ºC), hydrogen at room temperature, and water at standard atmospheric pressure and a temperature above 100 ºC.

If a gas in container is heated, the pressure increases. If it is cooled, the pressure drops. If the gas is placed in a sealed container and then the volume of the container is reduced, the compression heats the gas. If the volume of the sealed container increases, the decompression cools the gas. If the temperature becomes sufficiently high, certain gases, such as hydrogen, will rapidly combine with other gases such as oxygen or chlorine. This is combustion.

Some chemical reactions between gases and other substances occur more slowly; an example is the gradual oxidation of iron to form iron oxide (rust). In this case, the oxygen is gaseous at room temperature, while the iron and the iron oxide are solids. When a gas in the gaseous state is cooled to a low enough temperature, it may become a liquid or a solid. For example, if nitrogen is cooled down to a temperature far below zero Celsius , it liquefies. Another gas, carbon dioxide, becomes a solid known as dry ice, skipping the liquid phase. Some gases are lighter than air, for example helium and hydrogen, and can thereby be used for lifting solid objects, like balloons or even vessels.
