What is the working principle of dehumidifier?
Working principle. The heart of the dehumidifier is a desiccant rotor having high moisture adsorption capacity. the rotor is divided in two sectors, process and regeneration (reactivation). The rotor rotates slowly between these two sectors. The dehumidifier has two air streams, process and reactivation.
When, how and why to use a dehumidifier?
You know you need a dehumidifier if:
- Moist or wet stains are present on walls or ceiling.

Do dehumidifiers really work?
Yes, they do! The internal units within a dehumidifier have been designed to pass the hot humid air over the cool condenser coils, turn the water vapor into the water by condensation, and collect the extracted water in a reservoir that comes with the device. Different units of dehumidifiers have different capacities.
