According to different classification methods, industrial nitrogen generators can be divided into three types: cryogenic air separation, molecular sieve air separation (PSA) and membrane air separation. A nitrogen generator is a nitrogen production equipment designed and manufactured according to pressure swing adsorption technology. It uses high-quality imported carbon molecular sieve (CMS) as adsorbent and uses the pressure swing adsorption principle (PSA) at room temperature to separate air to produce high-purity nitrogen.
