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.

The desiccant rotor on a dehumidifier is a special dehumidification component that typically uses solid desiccants. Coating, impregnating, or forming desiccant materials on the supporting rotor structure to effectively remove moisture from the air. This type of rotor has a wide range of applications, such as preventing corrosion, reducing the growth of microorganisms (mold, bacteria, etc.), removing condensate, and improving human comfort. Therefore, dehumidification wheels are widely used in industries such as pharmaceuticals, food, chemical manufacturing, and electronic product manufacturing.
