HUILIN small liquid nitrogen generator adopts cryogenic mixed working medium throttling refrigerator. 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.
HUILIN small box liquid nitrogen generator has the characteristics of automatic unattended operation, small floor space, fast liquid nitrogen output, mature technology, convenient maintenance and low noise.
Huilin small liquid nitrogen generator is widely used in embryo breeding, clinical medicine, seafood quick-freezing and other fields. It can produce liquid nitrogen when it is energized, which solves the problem of the need of liquid nitrogen for local users who are inconvenient to transport liquid nitrogen. Huilin has been provided hundreds of small liquid nitrogen engines for users in various laboratories around the world.
