Information

GM Cryocooler Introduction
Gifford-Mcmahon cryocooler (abbreviated GM cryocooler) is a regenerative small-size low-temperature cryocooler, which uses the principal of adiabatic degassing expansion (also known as the Simon expansion) to obtain low temperature.


Features
Simple structure, reliable operation, stable performance and long service life


Function
It is mainly used in Cryopump, cold trap, material performance test, detector cooling, cryotronics, customized cryogenic system, and superconducting magnet.
