Nitrogen LiquefierWorking Principle
The nitrogen liquefier employs an advanced cryogenic mixed refrigerant throttle refrigerator.It utilizes a regenerative multi-component mixed refrigerant throttle cycle. By blending components with high, middle, and low boiling points, the system efficiently aligns each component with its cooling temperature range, effectively transitioning from ambient temperature down to -196 °C., achieving the efficient liquefaction of nitrogen (-180 °C @ 0.6 MPa).
Features:
1. Fully autonomous functioning: Eliminates the need for constant supervision, offering seamless operation.
2. Space-saving design with a minimal land footprint, and a low height, with a maximum Height≤2500mm), making it perfect for confined areas.
3. Fast liquid nitrogen generation: Facilitates rapid output within just 1.5 hours of start-up.
4. Time-tested technology Provides Safe, reliable, and low-maintenance operation.
Equipped with standard refrigerator compressors, it enables easy repairs by those skilled in refrigerator maintenance. facilitating repairs.
