Name: Gas Drying Adsorb Water Molecular Sieve 3A Regenerated by Heat Manufacturers - Low Price - Chemxin
Brand: Chemxin
SKU: 21149208

gas drying adsorb water molecular sieve 3a regenerated by heat.

Chemxin Molecular Sieve type 3A, Its effective aperture is 3 eh, mainly used for absorbed water(the diameter of water molecules is about 2.8 eh), not adsorb any molecular diameter greater than the water and thus play a role in screening, With the adsorption rate was fast, regeneration frequency ,more crash-resistant, high strength and Strong anti-pollution ability, adsorption efficiency and long life for high-end sector of choice for high-precision dry moisture products, Control of the cavity insulating glass has long maintained at the dew point below -60 .

2. Regeneration:

Chemxin molecular sieve Type 3A can be regenerated by either heating in the case of thermal swing processes; or by lowering the pressure in the case of pressure swing processes.
To remove moisture from a 3A molecular sieve, a temperature of 200-230°C is required. A properly regenerated molecular sieve can give moisture dew points below -100°C.
The outlet concentrations on a pressure swing process will depend on the gas present, and on the conditions of the process.

3. Size:

3A - Zeolite are available in beads of 1-2 mm(10x18 mesh), 2-3 mm(8x12 mesh), 2.5-5 mm(4x8 mesh) and as powder, and in pellet 1.6mm, 3.2mm.

4. Attention:
To avoid damp and pre-adsorption of organic before running, or must to be reactivated.
