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.

1. Are you manufacture or trading comany?

We are professional factory in oxygen generator, nitrogen generator, liquid nitrogen generator and air separator generator field for about 20 years.

Our factory located in Hangzhou city, covering an area of 20,000 square meters.

2. Which part will you provide?

We will provide whole set of the generator, including air compressor, air purification system, buffer tank, PSA system. If required we will also provide pressurization system and filling system.

3. What certifications do you have?

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.
