SHI Cryogenics Group’s HC-4E1 compressor is designed to operate the Marathon® CP-8, CP-8LP and CP-250LP cryopumps along with a range of 10K cryocoolers. The compressor utilizes a water-cooled rotary compressor capsule designed exclusively to deliver high pressure, oil-free helium to cryogenic refrigerators. It is a reliable and compact system for both vacuum and laboratory operations, and like all Sumitomo Cryogenics products, is supported by a worldwide sales and service center network. For customers wishing to upgrade their old systems, the HC-4E1 is a direct replacement for the HC-4MK2-1 and HC-2D-1 compressors.
