Dry air is a laboratory phenomenon. Atmospheric air will always contain moisture, often in quantities that can cause problems to materials, manufacturing processes and create human discomfort. Spaces containing high airborne moisture content (humidity) will suffer from damp, condensation and unpleasant odours. Traditionally the problem was disguised by the use of heat or ventilation. This process is exceptionally energy inefficient and reliant on introducing outside air that is generally not suitable unless expensively heated.

By comparison, Calorex Dehumidifiers recirculate the internal air and positively, in a controllable, efficient manner remove moisture from it. In doing so, the humidity can be controlled without the need for heat. Further, outside air conditions have little effect on the dehumidification efficiency.

As an added bonus Calorex dehumidifiers will convert latent energy recovered from the air during the dehumidification process into sensible heat. Typically 2.5kW of background heat for every 1kW of power consumed can be given back to the room, so turning unwanted moisture into heat at a fraction of the direct heating cost!
