Features:
1. Automatic operation ensures continuous performance without the need for constant supervision.
2. Compact design with minimal land usage and a maximumheight of
2500mm.
3. Fast production of liquid nitrogen: Takes only 1.5 hours from start-up to output. 4. Proven technology,ensuring safe, reliable operation and simple maintenance.
Utilizes standard refrigerator compressors available in the market; easily serviceable by refrigerator technicians, making it efficient andcost-effective.
5. Continuous operation with no need for downtime or defrosting.
Nitrogen LiquefierWorking Principle:
Utilizes a cryogenic mixed refrigerant throttle refrigerator. This innovativenitrogen liquefier employsa regenerative multi-component mixed refrigerant throttle refrigeration cycle, selecting high, middle, and low boiling point pure components. These components form a multi-component mixed refrigerant, effectively aligning the refrigeration temperature zones of each boiling point component. It cools from ambient temperature to -196 °C,achievingthe purposeof efficient nitrogen liquefaction (-180 °C @ 0.6 MPa).
