CH/DE Service

CH and DE Series Cryocoolers Service Options

SHI CH and DE Series Cryocoolers can be serviced via “hot swap” on-site by the customer or by an SHI factory-trained technician, without removing the cryocooler for return or replacement.  This unique service option is the result of the high-quality, ultra-reliable Displex® Cryocooler technology found in all CH and DE Series Cryocoolers.  Displex Cryocoolers have a long and successful operating history, and feature a pneumatic drive that optimizes performance and reliability and permits quick and easy removal of the displacer assembly for maintenance.

Performing hot swap service lowers the total cost of ownership by:

  • Eliminating the cost of shipping a complete cryocooler to a service center
  • Eliminating labor costs associated with complete disassembly of the cryocooler from your system
  • Minimizing the “down time” of your system for service or repair
  • Minimizing the required capital investment in spare parts

In addition, these cryocoolers can be returned to one of SHI’s service centers.  Product repairs and refurbishments performed at SHI Service Centers include:

  • Flow check of all internal parts to ensure optimum refrigeration capacity
  • Replacement of required wear items-seals, valve disc, valve stem, capillaries and displacers, when necessary
  • Performance testing to factory specification
  • Leak check, both pressurized and for vacuum integrity, where applicable
  • Full factory warranty
