Helium refrigerators - HELIAL range [ Return towards Cryogenics for scientific research ]

Quickly deployable and easy-to-use liquefiers

HELIAL EVOLUTION is the new range of refrigerators that can provide cooling power thanks to helium at 4.5 K from 100 kW to 1kW for different applications.

Intended for research centers having cryogenic applications (synchrotron, cold neutron source, cyclotron, accelerator, space simulation chamber), HELIAL evolution becomes integrated within a system going of the storage of gaseous helium to its distribution towards the customer application. The cooling power is dedicated to diverse applications: superconductivity, nanotechnology, biology, quantum physics, space etc.

Air Liquide offers its customers a turnkey refrigeration system, HELIAL EVOLUTION and all its related components. All HELIAL EVOLUTION refrigerators are fitted with turbines, the core of the refrigeration process, developed by Air Liquide. These turbines operate under static gas bearing technology, which means they can reach rotation speeds of up to 300,000 revs per minute, with an MTBF of 150,000 hours.
