China nitrogen generator up to 99.995% high purity qualified supplier


Welcome to CANGAS PSA Nitrogen gas generators. We are the market leaders for on-site production of Nitrogen and oxygen gas. PSA Nitrogen generators have become the preferred source of producing on-site Nitrogen gas. Nitrogen plants based on Pressure Swing Adsorption (PSA) technology are reliable and economical. In fact, most customers recover their payback vis-a-vis cylinders, in less than 2 years. We offer whole series of Standardized Models for various purities and capacities.

What is PSA technology?

Air is composed of 78% Nitrogen and 21% Oxygen. PSA Nitrogen generation technology works on the principle of air separation by adsorbing Oxygen and separating Nitrogen.

Pressure Swing Adsorption (PSA Nitrogen) process comprises of 2 vessels filled with Carbon Molecular Sieves (CMS). Pre-filtered compressed air is passed through one CMS filled vessel. Oxygen is adsorbed by the CMS and Nitrogen comes out as the product gas. Upon saturation of the CMS in the vessel, the process switches nitrogen generation to the other vessel, while allowing the saturated bed to undergo regeneration by depressurization to atmospheric pressure. The waste gas (oxygen, carbon dioxide, etc.) is discharged into atmosphere. The cyclical nature of the process between the two vessels ensures continuous production of pure Nitrogen.
