Hydrogen liquefiers - HYLIAL range [ Return towards Cryogenics for scientific research ]

Efficient easy-to-use liquefiers

HYLIAL is a range of hydrogen liquefier with a helium loop that can supply between 600 and 1000 L/hr of liquid hydrogen.

Gas liquefied in this way can be stored and then redistributed to power various applications: fuel cell vehicles, space test centres, microelectronics etc. Air Liquide DTA can provide a comprehensive system including the liquefier and all related components required for storage.

HYLIAL liquefiers are fitted with 2 static gas bearing turbines which form the core of the liquefaction system. They provide cold power to the helium loop thereby allowing the hydrogen to liquefy.

Range
