Desiccant dehumidifiers are devices that reduce humidity in the air using a desiccant material, which absorbs moisture. Unlike traditional refrigerant dehumidifiers, they work effectively in low temperatures and are often used in spaces like basements, storage areas, and industrial settings. These dehumidifiers typically contain a rotating wheel made of a desiccant substance, such as silica gel or zeolite. As air passes through the wheel, moisture is captured, and the drier air is released back into the environment. This process helps prevent mold growth and protects items from damage due to excess humidity.
