Introduction to Liquid Nitrogen Machine Components:

1. Air compressor (imported or domestic), providing raw air.

2. Air buffer tank.

3. Precision filter, filtering impurities in the raw air with a filtration accuracy of 0.01um.

4. Pre-cooling unit, cooling the air to approximately 8°C.

5. Water separator, removing condensed water from the pre-cooled air.

6. Molecular sieve purifier, eliminating moisture, carbon dioxide, and most hydrocarbons.

7. Purifier electric heater.

8. Fractionation tower, where purified air enters the cold box of the fractionation tower and undergoes a series of heat exchanges and distillation to obtain the product.

9. Fractionation tower electric heater.

10. Turbine expander, providing the cold source for the complete set of equipment.

11. Liquid pump or oxygen compressor, increasing product pressure for bottling or pipeline transportation.

12. Instrument control and electrical control system, etc.

The liquid nitrogen machine equipment is newly developed and designed, capable of producing industrial oxygen, medical oxygen, liquid oxygen, nitrogen, and liquid nitrogen, among other products. Our company has mature expertise in applying this technology.
