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. It has many advantages such as simple structure, reliable operation, stable performance and long service life, etc.
Vacree Technologies Co., Ltd. (CETC No. 16 Research Institute)has nearly 40 years' experience in R&D and production of GM cryocoolers and Solver cryocoolers. There are series of cryocoolers. GM cryocooler has ever obtained the second prize of Technological achievements by Ministry of Electronics Industry, the third prize of Science and Technology in Anhui Province, and has been identified as state-level new products, high-tech products in Anhui Province.
