Nitrogen PSA generator

The technology of air-to-nitrogen production with the use of adsorption processes in nitrogen generators is well studied and widely applied at industrial facilities for the recovery of high-purity nitrogen.

The operating principle of a nitrogen generator utilizing the adsorption technology is based upon the dependence of the adsorption rates featured by various gas mixture components upon pressure and temperature factors. Among nitrogen adsorption plants of various types, pressure swing adsorption (PSA) plants have found the broadest application world-wide.


Nitrogen is an odorless, colorless, non-toxic and non-flammable gas, at room temperature and atmospheric pressure. 78% of our atmosphere is made up of it. N2 is used as an inert gas in Blanketing Systems, Electrical Systems, the Chemical Industry and the Food Packaging Industry.

Even though N2 is non-toxic, it can still act as an asphyxiant and special precautions should be taken in confined areas. Always keep areas well ventilated. Nitrogen Generator South Africa.
