[ Products Description ] 
The life span of freezer system is mainly determined by the refrigerant leakage time, this was caused by harmful substances produced from trace moisture and refrigerant reaction. Molecular sieve is the most powerful product to removal trace water. Our molecular sieve are designed to protect the refrigerant dew point in a much professional way.
The technical explanation for refrigerant molecular sieve.
The molecular sieve should adsorb noting except water.
The molecular sieve should not react with of effect the stability of refrigerant.
Require very low dew point control.
Require very low abrasion.
So refrigerant need specialized molecular sieve desiccant, our molecular sieve XH-7is suitable for some very stable refrigerant such as R-134, and the type XH-9 can suit for any refrigerant.
