A common 4A molecular sieve application is dehydrating compressed air. In a desiccant air dryer molecular sieve is regenerated by heating and purging. Regeneration temperatures must be 400° to 600° F, but are not to exceed 1000° F. The degree of regeneration depends on the temperature reached in purge. Molecular sieve is often used as a polishing layer in air dryers to reach dewpoints of -120° F.  

Main Applications

1)      Deep drying of air, natural gas, alkane and refrigerant.

2)      Generation and purification of argon.

3)      Static dehydration of electronic element, pharmaceutical and unstable materials.

4)      Desiccant for paint, dope and foul etc.

Packaging    

50kg or 150kg per  iron drum.
