Introduction to liquid nitrogen machine components:

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

2. Air buffer tank

3. Precision filter, removing impurities from 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 to produce industrial oxygen, medical oxygen, liquid oxygen, nitrogen, and liquid nitrogen, among other products. Our company has mature expertise in applying this technology.

Advantages of Industrial Liquid Nitrogen Machines

1. Advanced technology: Our company uses new technology to replace the older generation Stirling refrigerator technology for producing liquid nitrogen.

2. Low energy consumption: The new technology we employ significantly reduces the unit energy consumption of liquid nitrogen products, saving 10-20% energy compared to similar products.

3. High purity: The purity of liquid nitrogen can reach up to 99.999%.

4. Small footprint: Utilizes a skid-mounted structure for indoor installation. Widely used in university laboratories and research institutions.

5. Maintenance cycle: Long maintenance intervals, minimal workload, and simple maintenance.

6. Stability: High operational stability, with key components from well-known domestic and international brands, and few moving parts in the system.

This liquid nitrogen machine is mainly used for teaching in school laboratories, cryopreservation of sperm in animal husbandry, thermal expansion and contraction in bearing production, and preservation of beverages in cans and bottles.
