SHI Cryopumps

We partner with Synergy Systems Corporation to market SHI Marathon® cryopumps in specific geographic areas of the United States.

SHI Cryogenics is the world’s largest manufacturer of 10K and 4K cryogenic cold heads. Its acquisition of IGC-APD Cryogenics in 2002 married the strength of two of the leading producers of cryo pumps and compressors.

The Marathon family of pumps consists of four standard models, from 8-inch to 20-inch, and two low-profile models, 8-inch and 10-inch. Pumping speed (air) ranges from 1500 l/s to 9700 l/s. Unlike conventional cryopumps that use a technically dated mechanical scotch drive mechanism, SHI pumps feature a nearly vibration-free drive mechanism that enables servicing of the pump without breaking the vacuum and which extends operating life between service intervals.

SHI offers a family of both air and water-cooled compressors that will manage all Marathon-series pumps.

Detailed pump and compressor specifications will be found in the SHI Cryopumps Product Catalogue:
