Product Description
Chenrui liquid nitrogen machine High Efficiency Nitrogen Liquefier

Liquid nitrogen generator Working principle
Mixed-refrigerant Joule-Thomson (MRJT) refrigerator at low temperature ranges driven by single compressor with precooling is applied to liquefy nitrogen (-180ºC) 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 -196ºC. 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. 
-Capacity from 3L/h to 50L/h. Meet all your requirements.
-Low power consumption.
-Automatic operate. One key start.
-Small floor space.
-Durable. Can work 24 hours per day.
-One station of liqiuid nitrogen generator manufacture. (we supply liquid nitrogen generator,vacuum tube and liquid nitrogen dewar.)
