Helium Compressor Unit

Overview

Helium Compressor Unit

The helium compressor unit is jointly developed by MOON-TECH and Xi’an Jiaotong University. The helium screw compressor is mainly used in cryogenic refrigeration (as low as −271 °C), helping the Chinese Academy of Sciences develop a large low-temperature refrigeration system from the liquid helium to the superfluid helium temperature zone. This research and development project fills a relevant technological gap in China and reaches the international advanced level. The main technical indexes such as volume efficiency and isothermal efficiency of the helium compressor unit are at an internationally leading level.

Features

What the unit does

• Screw compressor design for continuous cryogenic duty
• Covers liquid helium through superfluid helium temperature zones
• Supports research in military, national defense, aerospace, nuclear technology and superconducting technology
• Fills a former technological gap in China; internationally advanced technical level

Applications

Where it runs

After being pressurized by the compressor, helium can be used for cryogenic research, gas phase analysis, welding, leak detection, chemical vapor deposition, crystal growth, and special gas mixtures — and as a standard gas, balance gas, medical gas, or for inflating a balloon, tube, or wetsuit.
