Product Description

99.9% Purity liquid nitrogen equipment is a necessary refrigeration machine for livestock production. The safe operation of 99.9% Purity liquid nitrogen equipment is very important for liquid nitrogen production and frozen semen preservation.


1.Parameter (Specification) of 99.9% Purity Liquid Nitrogen Equipment

Remark: For more models and specifications please contact us.

Compared with a gaseous air separation plants, a cryogenic liquid nitrogen plant need more cooling consumption.

According to different yield of cryogenic liquid nitrogen plant, we adopt various refrigerating cycle processes, like booster-expanding refrigeration, low temperature pre-cooler refrigeration, recycle compressor with high-low pressure expander refrigeration, etc. to reduce the power consumption.

DCS or PLC system are used, aided by on-site instruments, to make the complete system stable, reliable and easy to operate.


2. Quality Assurance of Cryogenic Liquid Nitrogen Plant

1) Strict contract auditing involved all departments to assure the feasibility of each order.

2) Process design and validation before bulk production.

3) Strictly control on all raw and auxiliary materials, all raw materials reach the world advanced level.

4) On-site inspection to all processes, inspection record keeps traceable for 3 years.

5) All inspectors are skilled with international certificates.

6) Qualified and professional welders guarantee welding quality.

7) 100% inspection of finished systems before shipment.

8) Regular training for inspection staff


3. Product Features of Cryogenic Liquid Nitrogen Plant

1. Simple operation, convenient maintenance and long maintenance cycle.

2. High reliability. The primary compression of 99.9% Purity liquid nitrogen equipment is more reliable than the tertiary compression of the oxygen compressor.

3. Good safety. The safety performance of the compression and internal compression process is higher. The evaporation pressure of 99.9% Purity liquid nitrogen equipment is high, and the hydrocarbon-accumulating device is reduced the possibility of fire hazard.

4. Compact and silent design. 99.9% Purity liquid nitrogen equipment is fully automatic operated, with energy-saving module built-in oil-free air compressor and sterile suction filter.
