Application
1. Drying of refrigerant and air in gas valve.
2. Remove carbon dioxide, ammonia, and methanol from the airflow.
3. Dry and purify hydrocarbons such as natural gas, LPG, air, inert gases and atmosphere.
4. Dehydration of electronic element,pharmaceutical,food,etc.
Notice
1. It can be regenerated by temperature and pressure change.
2. Before use, the molecular sieve could not be exposed to the air directly.
