Nitrogen LiquefierPrinciple of Operation
Employing a cutting-edge cryogenic mixed refrigerant throttle refrigerator, nitrogen liquefier. This system is built on a regenerative multi-component mixed refrigerant throttle cycle. By selecting pure components with high, middle, and low boiling points, it crafts a multi-component refrigerant that effectively matches refrigeration temperature zones of each boiling point. This allows cooling from ambient temperature to an impressive -196°C,fulfillingthe goal of nitrogen liquefaction (-180°C @ 0.6 MPa).
Distinguishing Features:
1. Automatic and Unattended Operation: Ensures convenience and efficiency.
2. Reduced land footprint, low height stature (maximum Height≤2500mm)
3. Swift Liquid Nitrogen Delivery: From start-up to liquid nitrogen output is a mere 1.5 hours.
4. Established Technology ,guarantees safe, reliable function and straightforward maintenance.
Compatible with ordinary refrigerator compressors, enabling those skilled in refrigerator repairs to easily service the unit.
