LIQUID NITROGEN GENERATOR

Technical solutions:

1.The liquid nitrogen generator equipment consists of three parts: nitrogen generator, refrigeration equipment, and Dewar tank. Its function is to automatically replenish liquid with one-key start-up. When the liquid nitrogen in the liquid nitrogen tank is lower than the set liquid level, the equipment automatically starts. The principle of automatic cascade refrigeration of mixed working fluids, the nitrogen is gradually cooled from the ambient temperature to the saturated condensation temperature of nitrogen liquefaction, the refrigerator can cool down to -196°, and the liquid nitrogen liquefied in the refrigeration evaporator is transported to the

liquid nitrogen tank. Save and obtain liquid nitrogen, the equipment automatically detects the liquid nitrogen level in the Dewar tank, and automatically controls the operation of the  equipment

Liquefied nitrogen generation and storage device 

Liquefied nitrogen generation and storage device that can be stored for a long time and can be used whenever necessary

Nitrogen (N2) present in a gaseous state is liquefied (liquefaction) at a cryogenic temperature of -196 degrees. Usually, related industries or research institutes purchase and use liquefied nitrogen. If not used for a certain period of time, liquefied nitrogen will be naturally vaporized and discarded to prevent explosion caused by rising tank pressure.
The liquefied nitrogen generation / storage device developed by CryoH&I can generate liquefied nitrogen by itself in a cryogenic environment. It also has a function of re-liquefying the boil-off gas generated by natural vaporization with a cryocooler. A cryocooler capable of implementing a -253 degree ultra-low temperature can be installed on the top of the tank to control the partial pressure of the gas, and safety has also been improved through various sensor monitoring and alarm programs and two-way communication functions.

In combination with PSA (Pressure Swing Adoption) process, only nitrogen gas is separated from general air and nitrogen is liquefied, so it can be used frequently according to its purpose.
It can be used profitably in research labs that conduct R&D by utilizing a small amount of liquid nitrogen in small and medium-sized spaces.

Product advantages:
1. Can be used to store and transport liquid nitrogen, liquid oxygen, liquid argon.
2. Different volumes, different pressures, more choices.
3. Spiral polished texture, beautiful appearance.
4. Brand accessories, reliable performance.
5. Floating support, lower heat loss.Product advantages:
ApplicationLiquefied nitrogen is used in hospitals, pharmaceuticals, and bio industries to store microorganisms, cord blood, cells, and vaccines, or to conduct related R&D. Liquefied nitrogen is also used in the food processing, recycling, superconducting fields, carbon dioxide capture, and gas separation and purification industries.
