What Are Desiccant Dehumidifiers?

Unlike a compressor dehumidifier, a desiccant dehumidifier is a specialized device that doesn’t use coils, refrigeration systems, or compressors to reduce humidity out of the air. This dehumidifier, on the other hand, will lower the moisture in your place using a process known as adsorption.

Desiccant-based dehumidification is mainly popular for low temperature dehumidifying since there’s no possibility of ice developing as well as intruding compressor operation.

Furthermore, desiccant dehumidifiers can get rid of a significant amount of humidity with more efficiency. As a matter of fact, this makes them a perfect option for heavy-duty moisture removal works in commercial, residential, and industrial spaces.

How Does A Desiccant Dehumidifier Works?

A desiccant dehumidifier works by utilizing a desiccant chemical to absorb damp from the air.  Then, a fan will draw the wet air towards the dehumidifier in which it is passed through the desiccant. After that, the desiccant moisture absorber is detained on a rotating wheel gradually.

The part of the rotating wheel that is not utilized is then heated up, so the humidity will drip out to the water tank. Then, it will reheat the air and pump the desiccated air back into your space. This will surely reduce the relative moisture in the atmosphere.
