Pulse Tube Cryorefrigerators

Features of Pulse Tube Cryorefrigerators:

  • Long mean time between maintenance
  • Minimal general maintenance
  • Ideal for vibration sensitive applications
  • Directly liquefy helium gas and recondense boil-off in liquid cryostat
  • Direct conductive cooling in dry cryostats (including low vibration options)

Cryoregrigerators

The PT400 Series Cryocoolers offer the most reliable, low vibration cooling to 4.2K of any product on the market today.

These systems are perfect for recondensing liquid helium and for cooling superconducting devices. Also used for precooling dilution, ADR and adsorption refrigeration systems.
