    Company Profile


    Product Tags



    NZN-L series liquid nitrogen equipment is based on the principle of pressure swing adsorption, using high-quality carbon
    molecules as adsorbents to produce nitrogen from the air under a certain pressure. The purified and dried compressed air is subjected to pressure adsorption and decompression desorption in the adsorber. Due to the kinetic effect, the diffusion rate of oxygen in the pores of the carbon molecular sieve is much greater than that of nitrogen. When the adsorption does not reach equilibrium, the nitrogen is enriched in the gas phase to form the finished nitrogen. Then the pressure is reduced to normal pressure, and the adsorbent desorbs the adsorbed oxygen and other impurities to realize regeneration. Generally, two adsorption towers are set up in the system, one tower absorbs nitrogen and the other tower desorption and regeneration. The two towers are automatically controlled by the PLC program to make the two towers work alternately. The finished nitrogen gas is then passed through a Stirling refrigerator to produce liquid nitrogen.
    Technical features The machine has the characteristics of simple process flow, normal temperature production, full automation, convenient start and stop, few consumable parts, easy maintenance, and low production cost.
