2. Working principle

Mixed-refrigerant Joule-Thomson (MRJT) refrigerator at low temperature ranges driven by single compressor with precooling is applied to liquefy nitrogen (-180℃) for Nitrogen Liquefier from TIPC, CAS. MRJT, a Joule-Thomson cycle based on reoccupation and multicomponent mixed-refrigerants through optimizing various refrigerants with different boiling points with a good match along with their respective efficient refrigeration temperature ranges, is an efficient refrigerator for the temperature range from -40 to -196℃.

The feature of this product is as following: the available mature commercial compressors and heat exchanges, high liquefaction efficiency, high reliability, no maintenance and long life.
