KDHRR20 Helium Reliquefier

KDHRR20 helium reliquefier takes KDE415-KDC6000 GM cryocooler as the core and provides the helium liquefying ratio of 15-20L/day, which consists of liquefying unit, auto-control, safety protection unit and elevator-platform. It can be used for helium liquefaction as well as re-liquefaction after liquid helium evaporation, and provides one ideal solution for liquid helium consumer.


Full automatically and reliably running without any watch monitoring;
Easy to remove, install and run in the lab using small floor area;
Mature technique and low maintenance cost as a result of G-M cryocooler for cooling;
System's pressure controlled by computer, which is safe and stable.
