Daikin GM-JT Cryocoolers from Janis and Sumitomo (SHI)
CG304SC, CG308SC and CG310SC (1 W, 3W and 5 W @ 4.3 K respectively)
Overview
Sumitomo acquired the cryocooler and cryopump business of the Daikin company in 2005. One of the cryocooler products acquired was the line of Gifford-McMahon (GM) refrigerators with a Joule-Thomson (JT) third stage, that were primarily designed for radiotelescope astronomers. These three stage cryocoolers have high cooling power at 4.3 K as well as very stable temperatures at the third stage.
