PSA Nitrogen Generators are used by customers in the chemical, food processing, pharmaceutical, metal processing and other industries. Professional Plastics supplies a full-range of plastic sheets, rods, tubing and films used in gas generation equipment. Plastics are also used in oxygen and ozone generators.

“PSA" stands for Pressure Swing Adsorption. This is the separation technology which separates Nitrogen and Oxygen Molecules from rich compressed air. Commercial nitrogen production process usually employ Carbon Molecular Sieves as adsorbents. These process depends on kinetic separation accomplished by a faster diffusion of oxygen molecules through the pore structure of the adsorbent. The Oxygen is adsorbed to its equilibrium value much faster than Nitrogen. This is because Oxygen which is smaller in size (kinetic diameter 3.46 A.o) diffuses much faster in Carbon Molecular Sieves than Nitrogen (kinetic diameter 3.64 A.o).
