Refrigeration around 80 K
Customized refrigeration systems for industrial, scientific and development customers
Whether for research centers using superconductors for their experiments (screening), for industrial customers wanting to equip themselves with test equipment (HTS superconductor cables) or specifically developed for large-scale development projects, our refrigeration systems are custom-designed.
To provide a cooling power around 80 K from 1 kW 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, on the Turbo-Brayton cycle, and nitrogen units based on the Claude cycle, as well as simple open systems using nitrogen.
- Screening (Synchrotrons, Particle Accelerators, Nuclear Fusion Reactors)
- HTS superconducting cable cooling
- Space simulation chambers
- 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
