Product Description LDH GAS SYSTEMS COMPANY LIMITED is a professional research and design production of gas equipment, cryogenic equipment and integrated environmental simulation equipment manufacturers. Gas equipment products include nitrogen generator, oxygen generator; Cryogenic equipment includes liquid nitrogen machine, liquid nitrogen treatment chamber, high and low temperature testing machine, natural gas liquefaction equipment; Environmental simulation equipment includes low oxygen enrichment, high temperature and low temperature, ultraviolet, wind, salt spray and other comprehensive environmental simulation. At the same time, system solutions can be professionally customized according to user needs.Working principleLDH GAS series liquid nitrogen equipment is based on the pressure swing adsorption principle, using high-quality carbon molecular sieve as adsorbent, under a certain pressure, from the air to produce nitrogen. After purifying and drying compressed air, pressure adsorption and decompression desorption are carried out in the absorber. Due to the kinetic effect, the diffusion rate of oxygen in the micropores of carbon molecular sieve is much higher than that of nitrogen. When the adsorption is not in equilibrium, nitrogen is enriched in the gas phase to form the finished nitrogen. Then decompression to atmospheric pressure, adsorbent adsorption of oxygen and other impurities, to achieve regeneration. Generally, two adsorption towers are set up in the system. One tower absorbs nitrogen and the other tower is desorption and regeneration. Automatic control by PLC program makes the two towers work alternately. The finished nitrogen is then passed through the refrigerator to produce liquid nitrogen.Product Parameters ModeLPLN-10LPLN-20LPLN-40LPLN-80LPLN-120LPLN-240LPLN-480LPLN-720LPLN-960LPLN-1200Capacity0.3-0.4L/H8-10L/day0.8-1L/H20-24L/day1.6-2L/H40-50L/day3L/H72L/day5L/H120L/day10L/H240L/day20L/H480L/day30L/H720L/day40L/H960L/day50L/H1200L/dayPurity≥99%≥99%Votage220VAC1P50Hz380VAC 3P 50Hz220VAC 1P 50Hz380VAC 3P 50Hz220VAC 1P 50HzPower(KW)24.57.512.5152745558492Area11.533.53.51030304040Size750*650*15001150*850*20001250*2000*20001250*2000*20001250*2000*20006000*1100*22008000*1700*23008000*1700*230012000*1800*235012000*1800*2350Ambient temperature0-30oC0-30oCNoise(dB)<50Db<50Db<50Db<50Db<55Db<72Db<78Db<78Db<78Db<78Db Training planTrain operators to operate the equipment skillfully;Let maintenance personnel master the daily maintenance and repair work of equipment;When the service personnel visit the user: understand the user's use situation, conduct secondary training for the operator, so that the operation and maintenance personnel further understand the equipment.
