Principle

NCHa gas purification system adopts catalytic reaction technology to promote the chemical reaction between oxygen impurities in gas and hydrogen added to produce water with the participation of catalyst, so as to achieve the purpose of completely removing oxygen impurities。

Components of Generator

NCHa type nitrogen purification device is composed of four parts: general nitrogen pretreatment system, automatic hydrogenation system, adsorption drying system and electrical control system. Specific accessories include touch screen orTD200, nitrogen analyzer, flow meter, mass flow controller, programmable controller, oxygen removal tower, drying tower, refrigerator, heat exchanger, filter, pipeline pneumatic valve, electromagnetic valve.
