Carbon Molecular Sieve
Explore Haina CMS grades for PSA nitrogen generation. The range below also includes CH3093, a carbon deoxidizer for a separate oxygen-removal duty.
CMS Grades for PSA Nitrogen Generation
Carbon molecular sieve acts as the adsorbent in PSA nitrogen-generation beds. Compare the required nitrogen purity and output with the relevant pressure and cycle conditions. Haina’s handbook provides separate performance tables for CMS-260, CMS-280, CMS-300 and CMS-330.
CH3093 is a carbon deoxidizer used in a heated purification process. It should be reviewed separately from the CMS adsorbent used in the PSA beds.
Industry Applications
See how carbon molecular sieve supports on-site nitrogen generation and how to match a grade to your operating conditions.
01 · PSA SYSTEMS
Industrial Nitrogen Generation
How it works Clean, dry compressed air enters a bed of carbon molecular sieve. Oxygen diffuses into the pores faster than nitrogen, leaving a nitrogen-rich stream. A second bed supplies gas while the first regenerates.
Why it matters On-site generation can supply a steady nitrogen header without relying solely on delivered gas.
02 · ELECTRONICS
PCB Assembly and Reflow
How it works Nitrogen lowers residual oxygen in the reflow oven. Where the process calls for a controlled atmosphere, this helps limit oxidation of exposed metal and molten solder.
Why it matters A dedicated nitrogen supply can support repeatable oven conditions across shifts and production lines.
03 · CHEMICAL PLANTS
Purging and Tank Blanketing
How it works Nitrogen displaces air during equipment purging and can maintain a low-oxygen atmosphere above liquids in a storage vessel where the process requires it.
Why it matters Routine blanketing and short purge events place different demands on the nitrogen system. A buffer vessel can help cover short peaks.
Where Haina Fits
Use the operating details below to compare carbon molecular sieve grades for your process.
PSA Nitrogen Generation
Compare Haina CMS grades at your target purity and flow. Include inlet pressure, feed-air dew point and cycle time so the comparison reflects your generator.
PCB Assembly and Reflow
Start with the oven’s residual oxygen limit, typical gas demand and peak draw. Use those inputs to shortlist a Haina CMS grade and size the PSA system.
Purging and Tank Blanketing
Share steady demand, peak purge flow and minimum supply pressure. Haina grade data supports CMS selection alongside the generator and storage design.
