Per product manual online: Cold head (expanders) are two-stage cryogenic refrigerators that operate on the Gifford-McMahon refrigeration cycle. Each uses helium gas from a helium compressor to produce the cold temperatures. Electricity to power the cold head�s valve motor is supplied from the compressor by the cold head cable. To be functional, the cold head is fitted with other parts or equipment so it can remove heat from the connected interfaces. Applications include laboratory systems for test sample cooling, cryopumps for clean, high-vacuum service and shield coolers and recondensers for cryogenic conservation, as in magnetic resonance imaging (MRI) medical diagnostic instruments.
The typical, complete operating system, using SCAI standard components, also requires and consists of the following pieces which are not included and must be soruced elsewhere : a helium compressor, interconnecting gas lines, interface attachments, and optional instrumentation.
