structure PSA nitrogen generator production N2, Entering the nitrogen liquefier into liquid nitrogen, and then stored in a liquid nitrogen tank for use.
Simple block diagram of the small liquid nitrogen generator 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 (-196 ° C @ 0.6 MPa) is achieved.
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.
5. No downtime for maintenance, no defrost.
