Engineering Principles & Working Mechanism

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.

HAVKOM Independent Engineering Assurance

Observing purity decline or reduced gas generation capacity in your nitrogen generator? Our engineering team analyzes CMS micropore health, dusting levels, and bed packing density to restore factory purity standards.

Frequently Asked Questions

What are the symptoms of failing CMS media?

A gradual drop in nitrogen purity, having to throttle output flow to achieve target purity, or observing fine black carbon powder ejected through exhaust silencers indicates bed breakdown.

Why is mechanical vibration mandatory during CMS re-bedding?

Gravity pouring leaves voids. Cyclic pressurization shifts the loose beads, causing rapid attrition into dust. Vibration packing ensures uniform density, preventing voids and dusting.
