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.
Application
Liquefied 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.
