4. 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 (-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.
More convenient:
1). Can equip with PRC multi monitoring and control system, enables parameters of capacity, purity, and pressure of product gases online display on panel screen, gives running problem alarm, and reminds of maintenance.
2). Turn-key solution and pre-commissioned.
3). Skid mounted design, easy installation.
5. Applications
1). fish boat,hotel and food processing plant: food quick-freezing,Beverage processing
2). hospital and beauty salon:Liquid nitrogen refrigerating apparatus,Vaccine preservation
3). laboratory: transducer calibration,Specimen preservation
4). farm: Embryo freezing instrument,freezing spermatozoon
Farm: Embryo freezing instrument,freezing spermatozoon, etc.
