Product Description

NUZHUO Portable Liquid Nitrogen Generator Small Scale For Laboratory 

With our liquid nitrogen generators, you can "produce" your own liquid nitrogen (LN2) without having to buy it, with great convenience, a stable supply of LN2, and many more. A continuous supply of LN2 is possible by connecting our liquid nitrogen generator directly to your LN2 cooled cryogenic storage tank. In addition, with backup power, LN2 can continue to supply power even in the event of a power outage caused by a natural disaster. This makes it possible to cryopreserve important biological samples in a stable and reliable manner. Our liquid nitrogen generators are now widely used to cool IPS cells, tissues, vaccines or cryogenic storage of livestock fertilized eggs

We specialize in making these liquid nitrogen producing plant of superior designing and cutting-edge cryogenic technology to achieve purity from 99.9% up to 99.999%, OR part per Million (PPM) as per the application and requirement of the end user. We are offering a wide range of capacities from 10 Liters/Hour to 5 Liters/Hour -50L/h Liquid Nitrogen producing machinery and equipment.

Working Principle

Following the principle of pressure swing adsorption, high-quality carbon molecular sieve is used as the adsorbent. Under certain pressure, due to the dynamic effect, the diffusion rate of oxygen and nitrogen on the carbon molecular sieve is different. The oxygen molecules are adsorbed by the carbon molecular sieve in large quantities. Nitrogen molecules are enriched in the gas phase to achieve oxygen and nitrogen separation. Since the adsorption capacity of carbon molecular sieve for oxygen varies significantly with pressure, reducing the pressure can adsorb the oxygen molecules adsorbed by the carbon molecular sieve, so that the carbon molecular sieve can be regenerated and reused. Two adsorption tower processes are adopted, one is for adsorption and nitrogen production, and the other is for desorption and regeneration, alternating cycles and continuous production of high-quality nitrogen.
Configuration of LN2 Generator

No	MAIN PART	FUNCTION
1	Air compressor	Air is used as raw material to collect & compress air to 8 bar, (Screw type)
2	Refrigerated dryer	The standard configuration removes moisture and impurities in the air, so that the air dew point reaches -20°C (the intermediate configuration uses an adsorption dryer, and the dew point reaches -40°C; the advanced configuration uses a combined dryer, and the dew point reaches- 60ºC).
3	Precision Filter	A/T/C three-stage filter to remove oil, dust and impurities.
4	Air buffer tank	Store pure and dry air for subsequent adsorption and separation of nitrogen as raw material storage.
5	Adsorption tower	A&B adsorption tower can work alternately, regenerating adsorption, filling sodium molecular sieve to filter out oxygen molecules.
6	Nitrogen Analyzer	Real-time monitoring and analysis of nitrogen purity, indicating that the equipment is working normally and alarming.
7	Valves & pipelines	Intelligent control valves realize automatic operation of equipment, PLC control, SUS304 pipelines.
8	Nitrogen Buffer Tank	Store nitrogen with qualified purity, which can be directly piped or used for bottle filling.
9	Liquid Nitrogen Generator	Cooling the nitrogen gas to Liquid nitrogen with -196ºC.
10	Cold Water Chiller	Provide the circulating cold water to Liquid nitrogen generator.
11	Liquid Nitrogen Dewar	Use to collect and storage the liquid nitrogen.
