Mini Liquid Nitrogen liquefaction machine
Nitrogen Liquefier Working principle
The cryogenic mixed refrigerant throttle refrigerator is adopted in this nitrogen liquefier. It is based on the regenerative multi-component mixed refrigerant throttle refrigeration cycle. The high, middle and low boiling point pure components are selected to compose multi-component mixed refrigerants. The relay matching of effective refrigeration temperature zones of each boiling point component is realized. It can be cooled from ambient temperature to -196 ° C, the purpose of nitrogen liquefaction (-180 ° C @ 0.6 MPa) is achieved. More small Nitrogen generator for you to choose.
Features
1. The machine runs automatically and nobody is on duty.
2. Less land occupation, low height (maximum Height≤2500mm)
3. Quick speed of liquid nitrogen output: It only takes 1.5 hours from start-up to liquid nitrogen output.
4. Mature technology ，Safe and reliable operation and easy maintenance.
With ordinary refrigerator compressors on the market, people who can repair refrigerators will ba able to repair it.

Application
1. Application of liquid nitrogen in animal husbandry.It is widely used in the improvement of livestock freezing matching technology and embryo transfer of livestock and many kinds of animals to prepare living embryos.
2. Liquid nitrogen in medical miracle application.Cryogenics, clinical medicine.Liquid nitrogen is the most widely used refrigerant in cryosurgery.It's one of the best refrigerants ever invented. You put it in a cryogenic machine. It's like a scalpel.
3. Application of liquid nitrogen in food industry.The application of liquid nitrogen in food quick-freezing has a fast freezing rate (about 30-40 times faster than the usual freezing method).
4. Application of liquid nitrogen in the electronic industry.Superconductivity skills, electronic components manufacturing and testing, low temperature ball grinding skills, green cutting skills and so on.
5. Other applications of liquid nitrogen. Application in HTS power cable development;It is used to freeze the liquid pipeline in emergency maintenance. Low temperature stabilization and quenching of materials; Liquid nitrogen cooler skills and so on.
