  • DUAL HELIUM COMPRESSORS
    Publication number: 20220003462
    Abstract: This invention relates to oil lubricated helium compressor units for use in cryogenic refrigeration systems, operating on the Gifford McMahon (GM) or Brayton cycle. The objective of this invention is to provide redundancy by having a water cooled compressor manifolded to an air cooled compressor and sensors to detect faults so that an expander can be kept running if there is a failure in either the water or air supply.
    Type: Application
    Filed: September 21, 2021
    Publication date: January 6, 2022
    Applicant: Sumitomo (SHI) Cryogenics of America, Inc.
