SHI designs and manufactures two lines of two-stage Gifford-McMahon Cryocoolers:
SHI’s RDK/E-Series Cryocoolers are recognized as the most reliable and versatile systems available in the marketplace. They feature high cooling capacities, compact designs and are orientation-free. Models like the RDE-412D4 are the standard for MRI and other superconducting magnets. They 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.
SHI’s CH-Series Cryocoolers are versatile, closed-cycle systems featuring Displex® technology, which has been recognized as the industry standard since we developed the technology over 50 years ago. The original pneumatic drive, limiting the number of wear parts in the refrigerator, combined with state-of-the-art design features, results in superior performance and low maintenance costs. Select models also feature Whisper® technology for quieter operation. They have proven reliability in thousands of applications, including MRI, cryopumping, research and other custom low temperature applications.
