Carbon Molecular Sieve (CMS) is an engineered microporous carbonaceous adsorbent tailored for PSA nitrogen generation. Exploiting kinetic diameter differentials, smaller oxygen molecules diffuse into the CMS pore network thousands of times faster than nitrogen, allowing clean, dry nitrogen to discharge as product gas.
CMS micropore consistency dictates nitrogen recovery efficiency and compressor air factor. CMS 220, CMS 240, and CMS 260 grades provide tailored kinetic selectivity for various purity targets ranging from 95% to 99.999%.
At HAVKOM Engineering, we supply certified premium CMS media, manage complete spent adsorbent vacuum extraction, execute vibration-assisted dense packing to eliminate bed voidage, and perform post-loading calibrated purity certification.
