Nitrogen Liquefier Working principle
Mixed-refrigerant Joule-Thomson (MRJT) refrigeratorat low temperature rangesdriven by single compressor with precooling is applied to liquefy nitrogen(-180℃) for Nitrogen Liquefierfrom TIPC, CAS. MRJT, aJoule-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.
