The DEV MS-5A Molecular Sieve, manufactured by Devson is the calcium form of Type A zeolite with a nominal pore size of approximately 5 Å. Designed for selective adsorption of small polar molecules and straight-chain hydrocarbons, DEV MS-5A provides high adsorption capacity, thermal stability, and long-term operational reliability. It is particularly suited for industrial gas purification, separation, and drying applications where precise molecular selectivity is required.

  • Uniform 5 Å microporous structure enables selective adsorption of water, CO₂, and small hydrocarbons.

  • Exhibits excellent thermal and mechanical stability, allowing prolonged use in fixed-bed or cyclic adsorption systems.

  • Maintains high adsorption capacity over multiple regeneration cycles.

  • Engineered for high operational reliability in demanding industrial processes.

Functional Description

The performance of DEV MS-5A is governed by its calcium-exchanged Type A lattice, which creates uniform pores that selectively admit molecules up to 5 Å. Water, CO₂, and small straight-chain molecules are efficiently captured, while larger or branched molecules are excluded. The robust crystalline framework ensures mechanical strength and thermal durability, making DEV MS-5A suitable for repeated adsorption and regeneration cycles in industrial gas processing applications.

Advantages

  • Achieves ultra-low moisture and CO₂ levels in gas streams.

  • Provides efficient removal of trace contaminants, protecting downstream equipment.

  • Maintains high adsorption efficiency over multiple cycles, ensuring long service life.

  • Supports cost-effective regeneration, reducing operational expenditure.
