Operating Principles

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.

This machine has the characteristics of simple process flow, Normal temperature production, high automation,

easy to start and stop, less damaged parts, easy maintenance and low production cost.

o vacuum, and the adsorbed moisture, carbon dioxide, nitrogen and a small amount of other gases are respectively pumped out to the atmosphere, and the adsorbents are regenerated. The above process steps are implemented by PLC and switch valves system to realize automatic control.
