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.
