Refrigeration around 80 K

Customized refrigeration systems for industrial, scientific and development customers

Our 80K refrigerators are tailor-made to meet the specific needs of the application.

Whether for research centers using superconductors for their experiments (screening), for industrial customers wanting to equip themselves with test equipment (HTc superconductor cables) or specifically developed for large-scale development projects, our refrigeration systems are custom-designed. 

To provide a cooling power around 80K from 1kW to several tens of kW, and according to the constraints of the application, several processes are proposed, and in particular helium or nitrogen refrigerators or systems combining both. AIR LIQUIDE offers helium units based on the Brayton cycle, nitrogen units based on the Claude cycle, and simple open systems using nitrogen.

 

Applications served

  • Screening (Synchrotrons, Particle Accelerators, Nuclear Fusion Reactors)
  • HTc superconducting cable cooling
  • Space simulation chamber

 

Customer benefits

  • Easy to use: user-friendly interface with touch screen control, automatic operation driven by a control system, remote access by modem / internet
  • Reduced maintenance: self-diagnosis allowing to anticipate breakdowns
  • Low operating costs: reduced consumption of utilities (compressed air, nitrogen, water, electricity), compact system easily integrated into existing infrastructures

 

Main technical features

  • Air or water cooled compressor
  • De-oiling and cycle pressure management system
  • Automatic management of the compressor, system cooling, nominal operation, shutdown
  • Reliable systems thanks to redundancy of certain components
  • Optional storage and distribution equipment

 

Standards

  • ASME Stamp U (USA) - HPGSL (Japan) - AQSIQ (China)
  • CE / ASME marking
