PSA Nitrogen Generator

Summits manufacture the best in class PSA Nitrogen Generators upto a capacity of 1000 Nm3/hr and purities upto 99.9995%.

The major components of PSA Nitrogen Generator are a pair of Adsorbers, surge tanks, switching valves, intelligent PLC with touch screen display, Gas analyzer and other instruments


The adsorber columns of PSA Nitrogen Generator are filled with very high quality Carbon Molecular Sieves (CMS) which preferentially adsorb Oxygen, CO and Co2 whereas Nitrogen is not adsorbed by CMS due to its larger molecular size and lower diffusivity, passes through the vessel to the surge tank. Based on the pre-fixed time interval the online adsorber switches to desorption mode and all contaminants in the CMS are purged out to the atmosphere. Gas analyzer fitted in the PSA Nitrogen generator monitors the gas concentration and compares with the pre-set value and allows the product gas to the storage tank. If gas concentration is more than the pre-set value the PLC switches the vent valve and purges out the gas till it reaches the required purity.
