Molecular sieve is a new style adsorbent without polarity. It can seperate oxygen and concentrate nitrogen under normal temperature. CMS mainly used in industrial gas pressure swing adsorption from high purity nitrogen. Our CMS product has the character of large nitrogen yield capacity and high nitrogen recovery.Apply to chemical industry extensively,such as petrolchemical industry, electronic, food, medical, coal, heat treatment of metal ets. CMS technical data: 1) Grain diameter:1.0-2.0mm 2) Bulk density: 640-660g/l 3) Crushing strength:100N/granule 4) Adsorption cycle:2x58s
