The working principle of the desiccant wheel of the dehumidifier is to use the desiccant inside the wheel for dehumidification. The impeller is made of special composite high-temperature resistant materials and is divided into two fan-shaped areas, one for handling wet air and the other for regenerating air.

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.
