RDK-205D2

4K Cryocooler series
The RDK-205D2 two-stage Gifford-McMahon Cryocooler is one of SHI’s smaller-capacity 4K Cryocoolers, with a second-stage capacity of 0.5 W @ 4.2 K (50/60 Hz).  It operates with both air and water-cooled helium compressors

These 4K Cryocoolers can be found cooling a wide variety of analytical and experimental devices, and offer a very cost effective alternative to open-cycle liquid helium systems.
