Specialty Cryocoolers
SHI’s Specialty Cryocoolers encompass Gifford-McMahon, Joule-Thomson, Stirling and Pulse Tube technologies in temperatures from 4K to 77K.
In addition to our standard 4K, 10K and Pulse Tube Cryocoolers, SHI Cryogenics Group offers several cryocooler models designed for specialty research applications. These models include a 6.5K Gifford-McMahon Cryocooler and several single-stage Cryocoolers. Like other Cryocooler products, all Specialty Cryocoolers are backed by SHI’s worldwide sales, service and support network.
