When moist air passes through the adsorbent of the wheel, water molecules are adsorbed and removed, making the air dry. The processed dry air passes through the condenser, and the water vapor is condensed into water and discharged outside the machine, while the remaining dry air is discharged through the air outlet.

The desiccant wheel of a dehumidifier is a key component that consists of a continuously rotating honeycomb shaped wheel. This wheel is composed of wave like substances made of special composite high-temperature resistant materials, which carry moisture-proof agents such as high-efficiency specific silicone and carbon molecular sieves. This design provides a great dehumidification surface area.
