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.

Technical indicators and usage requirements

Ambient temperature: up to 45°C (summer)

Altitude: 180 meters

Liquid nitrogen output: 3L/h to 150L/h

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℃.
