Description

The pore size for molecular sieve is 4A^o. It is mainly used to adsorb water, methanol, ethanol, sulfureted hydrogen, carbon dioxide, ethylene, propylene, does not adsorb any larger molecular than its pore size , and often used as desiccant in industrial applications.

Technical Parameter:

Applications :

• Deep drying of air, Natural gas, alkane and refrigerant.
• Generation and purification of argon.
• Static dehydration of electronic element, pharmaceutical and unstable materials.
• Desiccant for paint, dope and foul etc.

Type 4A molecular sieve is typically used in regenerable drying systems to remove water vapor or contaminants which have a smaller critical diameter than four angstroms.
