XH-5 molecular sieve,XH-7 molecular sieve,XH-9 molecular sieve.
XH-5 molecular sieve is used mainly for refrigerant R12 and R22 in order to desiccate, purify and improve refrigeration effect.
XH-7 molecular sieve is used to dehydration and desiccation for new type R-134a,butane and other special refrigerants, which are used in refrigeratory, deepfreeze and air conditioning.
XH-9 molecular sieve is a common desiccation for new type refrigerants which are used in the air conditionings of car, ship and refrigeratory.
