Industrial cryogenics

Air Liquide’s mastery of cryogenics goes back to decades. Indeed, it forms the very foundation on which the company was built: in 1902 Air Liquide began using cryogenics to refrigerate liquid air to produce oxygen. This was the first of many scientific adventures and challenging projects we have taken on with pride over the years. We continue to create customized solutions for simple to complex applications in industries.

Industrial cryogenics at a glance

Cryogenics can be defined as the science of low temperatures, including refrigeration at below -180 °C and gas liquefaction.

Industrial cryogenics concerns applications where liquid gases such as nitrogen, carbon dioxide, helium and hydrogen are used as refrigerants to modify the physical properties of materials or to maintain temperature during process steps. They can also be used as an energy source to power various applications such as fuel cell vehicles and microelectronics.
