HPN PSA nitrogen generators use patented technology to produce
an uninterrupted supply of gaseous nitrogen, on site. This compact system of nitrogen generation is ideally suited for high flow applications that presently employ liquid nitrogen bulk delivery systems. With the HPN PSA nitrogen generators, the inconvenience of daily, weekly or monthly deliveries is eliminated. Nitrogen generation is accomplished at your location, continuously and reliably, requiring only a supply of compressed air.
HOW IT WORKS
The HPN PSA Nitrogen Generators operate on the Pressure Swing Adsorption (PSA) principle to produce a continuous stream of nitrogen gas from compressed air. Two towers are filled with carbon molecular sieve (CMS). Pretreated compressed air enters the bottom of the on-linetower and follows up through the CMS. Oxygen and other trace gasses are preferentially adsorbed by the CMS, allowing nitrogen to pass through. After a pre-set time, the on-line tower automatically switches to regenerative mode, venting contaminants from the CMS. Carbon molecular sieve differs from ordinary activated carbons in that it has a much narrower range of pore openings. This allows small molecules such as oxygen to penetrate the pores and be separated from nitrogen molecules which are too large to enter the CMS. The larger molecules of nitrogen by-pass the CMS and emerge as the product gas.
