Nitrogen LiquefierWorking principle
This advanced system employs a cryogenic mixed refrigerant throttle refrigerator, which forms the core of this nitrogen liquefier. It operates on a regenerative multi-component mixed refrigerant throttle refrigeration cycle, utilizing high, middle, and low boiling point pure components to create an efficient multi-component refrigerant blend. This technology ensures precise temperature zone matching across different boiling points, enabling cooling from ambient temperature down to -196 °C, achievingthe vital goal of nitrogen liquefaction at -180 °C @ 0.6 MPa.
Features:
1. Completely automated with no supervision needed; the system runs independently.
2. Space-saving design with minimal land use, and a reduced structural height (maximum Height≤2500mm) for versatile placement.
3. Swift liquid nitrogen production: Delivers output in just 1.5 hours post-activation.
4. Established, cutting-edge technology , providingreliable, safe operation and easy upkeep. Supported by standard refrigerator compressors, allowing
technicians proficient with refrigerators to confidently service the equipmentefficiently.
