Features: 1、Skid-mounted structure, easy installation, small occupying area. 2、The unique process and adsorber structure provide high nitrogen output rate, high recycling rate and obvious energy-saving effect. 3、The top-down gas flow, exclusive rate control and side-vibrating loading and sieving guarantee the static operation of molecular sieve without powdering or adding. 4、The air pretreatment system is equipped with dehydrator, degreasing devices, deduster and voltage regulator.[...]

Function: Increasing gas pressure according to individual requirement Working process: Increasing gas pressure in the cylinder by piston motion[...]

Air which was sucked in from air intake tower enters the suction air filter and after being removed of dust and other mechanical contaminants in it, it is compressed to the pressure of 1.0MPa by piston air compressor. Air from the air compressor is cooled to ~5℃ in the refrigeration unit, taken into the molecular sieve adsorber for removing H2O, C2H2 and CO2. There are two molecular sieve adsorbers which operate on a staggered cycle, i.e. one vessel is adsorbing the contained impurities while the[...]

Air which was sucked in from air intake tower enters the suction air filter and after being removed of dust and other mechanical contaminants in it, it is compressed to the pressure of 0.55MPa by centrifugal air compressor. Air from the air compressor is cooled to 10℃ in the direct contact after cooler and refrigeration unit after the water being separated its condensed water, taken into the molecular sieve adsorber for removing H2O, C2H2 and CO2. There are two molecular sieve adsorbers which operate[...]
