Features:
1. The machine operates autonomously, eliminating the need for constant supervision.
2. Compact design: minimal land usage, and low vertical clearance (maximum Height≤2500mm)
3. Rapid liquid nitrogen output: Achieves full output in just 1.5 hours after startup.
4. Advanced technology: reliable and safe operation, coupled with easy maintenance. Utilizing standard refrigerator compressors available on the market,
anyone skilled in refrigerator repair can easilyservice the machine.
5. Zero downtime maintenance; no need for defrosting.Nitrogen Liquefier
Working Principle: This nitrogen liquefier employs a cryogenic mixed refrigerant throttling refrigerator,
based on a regenerative multi-component mixed refrigerant cycle. By selecting high, middle, and low boiling point pure components to form a multi-component refrigerant mix, it ensures effective cooling across various temperature zones. Capable of cooling from ambient temperature to a frigid -196°C, it achieves nitrogen liquefaction at -180°C and 0.6 MPa.
