Description of the Liquid Nitrogen Generator :
The mixed refrigerant liquid nitrogen machine is based on a regenerative throttling refrigeration cycle. From the ambient temperature to the target cooling temperature, the high, medium and low boiling point pure components are preferably composed of multiple mixed refrigerants so that the effective cooling temperature regions overlap each other. In this way, the cooling temperature zone distribution matching is perfected, and the effective cooling temperature zone matching of each boiling point component is realized, thereby realizing high-efficiency cooling with a large temperature span, and a high throttling cooling effect can be obtained at a relatively small pressure difference. . Therefore, the mature single-stage refrigeration compressor in the general refrigeration field can be used to drive the closed-cycle mixed refrigerant throttling refrigerator to realize low-temperature refrigeration.
The Feature of the liquid Nitrogen Generator :
1) Fast startup and fast cooling. Through the mixed refrigerant concentration ratio, compressor capacity adjustment and throttle valve opening control, rapid cooling requirements are achieved;
2) The process is simple, the number of equipment is small, and the system reliability is high. The main components of the system use mature compressors, heat exchangers and other equipment in the refrigeration field. The system has high reliability and a wide range of equipment sources.

The pressure swing adsorption nitrogen generator uses air as the raw material and high-quality carbon molecular sieve as the adsorbent. It uses the principle of pressure swing adsorption and the molecular sieve full of micropores to selectively adsorb air to achieve the purpose of oxygen and nitrogen separation. The production of high-purity nitrogen mainly includes air pressure machine, filter, buffer tank, freeze dryer, adsorption tower, pure nitrogen storage tank and other equipment.
Nuzhuo liquefaction unit mainly includes pre-cooling compressor unit, pre-cooling air cooler, main cooling compressor unit, main cooling compressor unit, main cooling air cooler, cold box, liquid nitrogen tank, BOG recovery system and control system. The main/pre-cooling compressor unit includes the main/cooling screw compressor and its matching lubricating oil separator, lubricating oil precision filter, activated carbon adsorber, lubricating oil circulating pump and mixed refrigerant storage tank. The function of the MRC liquefaction unit is to provide refrigeration for the liquefaction of nitrogen by utilizing the principle of throttling refrigeration of mixed working medium regeneration. The lowest temperature of the unit can reach -180℃.
