Cryomech

Helium Reliquefiers

 

The Cryomech Helium Reliquefiers are designed to recondense the boil-off from liquid helium Dewar/Cryostats, and then return the liquid helium to the Dewar/Cryostat establishing a closed helium loop. It can be installed into Dewars already full of liquid helium or be utilized to liquefy helium gas from a gas cylinder to fill a Dewar.
