What is a Desiccant Wheel Dehumidifier and How Does It Function?

A desiccant wheel dehumidifier is a device that removes moisture from the air using a rotating wheel filled with hygroscopic (water-attracting) materials. This wheel absorbs moisture from incoming air, reducing humidity levels in the environment.

The U.S. Department of Energy defines a desiccant wheel as “a rotating device that uses desiccants to effectively remove moisture from air.” This technology is commonly used in various applications, including industrial processes and HVAC systems.

Desiccant wheels operate continuously by rotating through a process of adsorption and desorption. Air enters the system, passes through the desiccant material, and loses moisture. Heat is then applied to regenerate the desiccant by evaporating the absorbed water, allowing the wheel to continue the cycle.
