How does it work ?

        OXYMAT on-site nitrogen generators are based on the well-known PSA (pressure swing adsorption) technology. Two pressurized vessels with molecular sieves ensure continuous production for separation of nitrogen from other gases.

​

        An OXYMAT nitrogen generator consists of two pressure vessels storing carbon molecular sieves (CMS).

        Dry compressed air is blown through a valve to the first vessel where the pressure is built to reach 5 to 10 bar(g). The unwanted gas (oxygen) is adsorbed by the pellets during the building of pressure, and the nitrogen will pass through to the accumulation tank.

​

        While pressure is building up in one vessel, the other vessel is regenerating through a decrease in pressure, all to guarantee a continuous flow. Before the subsequent adsorption or desorption stage, a pressure equalization between the adsorption vessels will take place. When the pressure decreases in the first vessel, and the CMS pellets are saturated, the waste product is exhausted through the exhaust system. The pressure in the second vessel will now build up until the pressure between both vessels is once again equalized.
