All our nitrogen generators utilize carbon molecular sieves (CMS) to separate nitrogen from other air components. CMS traps oxygen molecules via adsorption at high pressure. When the CMS is saturated with oxygen, the pressure is decreased, allowing the oxygen to desorb and escape.

Unlike nitrogen membranes, CMS beds regenerate multiple times per hour to ensure the highest nitrogen purity. Additional materials are used in the columns to enhance the adsorption effect for optimal nitrogen purity.

Pressure Swing Adsorption (PSA)

To maintain a constant nitrogen flow, our generators employ two CMS beds. The process, known as Pressure Swing Adsorption (PSA), involves alternating between adsorption of oxygen in one bed and desorption in the other. When one bed is saturated and depressurized to release oxygen, the second bed begins absorbing oxygen, allowing nitrogen to continuously flow from the generator.
