The working principle of liquid nitrogen equipment

     Liquid nitrogen generatorIt refers to a device that uses air as a raw material and employs physical methods to separate oxygen and nitrogen, obtaining nitrogen gas. Industrial nitrogen generators can be classified into three types according to different classification methods: cryogenic air separation, pressure swing adsorption (PSA), and membrane air separation.

      Liquid nitrogen generators are nitrogen generation equipment designed and manufactured based on pressure swing adsorption technology. Liquid nitrogen generators use high-quality imported carbon molecular sieves (CMS) as adsorbents and employ the principle of room-temperature pressure swing adsorption (PSA) to separate air and produce high-purity nitrogen gas. Two adsorption towers are usually connected in parallel, and the air inlet valve is automatically controlled by an imported PLC for alternating pressure adsorption and depressurization regeneration, completing nitrogen-oxygen separation and obtaining the required high-purity nitrogen gas.

       Liquid nitrogen generatorIt subverts the fixed concept of "purchasing nitrogen" and is a groundbreaking liquid nitrogen preparation device, bringing convenience and stability through "producing liquid nitrogen". This liquid nitrogen generator can continuously supply liquid nitrogen by directly connecting to a liquid nitrogen cryogenic storage container used for storing cells and other biological samples.

       In addition, by installing a backup power supply, liquid nitrogen can be continuously supplied even in the event of a disaster when there is no power. It can also provide stable cryopreservation for valuable samples. Liquid nitrogen generators have been recognized by major private enterprises and university research institutes and are widely used in cryopreservation containers for iPS cells, tissues, and viruses, as well as in artificial insemination related to animal production.

       Liquid nitrogen generatorFour major advantages:

       1、No longer need to purchase liquid nitrogen; the liquid nitrogen generator only needs electricity to operate. In addition, in "ECO mode", operation can be controlled according to the remaining liquid nitrogen, thereby reducing power consumption. Stable and continuous cooling can also be achieved in countries, regions, and islands with underdeveloped infrastructure.

       2、No longer need to confirm the remaining liquid nitrogen. Since it can be stably and continuously supplied, there is no need for complex confirmation of the remaining liquid nitrogen. It frees you from tedious work.

       3、Stable cooling can be provided for important research subjects even in the event of a disaster. By connecting to a backup power supply, continuous cooling is possible even during a disaster. Continuous and stable cooling supply can also be achieved for important biological samples such as cells under research.

       4、Improves safety while simplifying complex processes. The management of liquid nitrogen is very cumbersome during safe transportation in the laboratory. In addition, safety is difficult to guarantee. The complex liquid nitrogen management and replenishment procedures are eliminated, improving safety.
