CHEMXIN molsiv adsorbents 4*8mesh molecular sieve type 4A zeolite for instrument drying

Product Description.

 and has an effective pore opening of about 4 angstroms (0.4nm). 4A molecular sieve will adsorb most molecules with a kinetic diameter of less than 4 angstroms and exclude those larger. It 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.

  1. By    National Standard HGT 2524-2010

  2. Offer    lifetime consultation on problems occurred

2. Typical Application:

- Used in instruments/devices for drying moisture;


3. Regeneration:

Chemxin molecular sieve Type 4A can be regenerated at a temperature of 250-280°C to remove the moisture. 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


4. Size: 

4A - 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.


5. Attention:

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