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.

We have ISO 9001:2008, ISO14001:2015, OHSAS18001: 2007 and many patent certifications.


4. How could I get a quotation?

It required to know the capacity, purity and pressure of the generator.

Different country, different voltages. So it's better noted what voltage of 3 phase and 1 phase when inquire ? 

In China, power supply is 380V(3phase)/220V(1 phase) /50Hz.
