Product Name:

Refrigerant Desiccant

Model:

Description:

The life span of freezer system is mainly determined by the refrigerant leakage time, the leakage is caused by the harmful substance corrosion which generating from the reaction of refrigerant and tiny moisture on the tube. Molecular sieve has the features of low dew point, high intensity, low abrasion loss and good chemical stability.

Product Name:

IG Desiccant

Model:

Description:

This insulating glass desiccant can deeply co-adsorb the resident moisture and organics in insulating glass, keep the IG clear and transparent even at very low temperature. Moreover, it does successfully avoid the tremendous uneven air pressure placed on the glasses, which is caused by seasons and day-night temperature changing.
