High performance portable dehumidifiers. Robust, portable dehumidifiers designed specifically to provide rapid drying solutions and humidity control.
Porta-Dry dehumidifiers are fully contained, packaged units which incorporate a fan and a totally CFC-free refrigeration circuit. A fan draws room air through the machine which firstly passes across a refrigerated heat exchanger (evaporator) that cools and allows moisture contained within the air to condense. The cooled, dry air then passes across a warm heat exchanger (condenser) where it is reheated as a result of the dehumidification process, before being returned to the room in a dry, warm state.Moisture removed from the air is collected in a reservoir where it is fed away to waste.
Due to the unique nature of a refrigeration circuit, energy removed from the air during dehumidification process is converted into usable heat. Typically for every 1kW of energy that a dehumidifier consumes, it will give out 2.5kW of heat; by removing the moisture from the air rather than heating it to a high temperature, Porta-Dry dehumidifiers will dry in a gentle and more controllable manner, alleviating possible material shrinkage and cracking problems associated with heating methods.
The process of dehumidification involves moisture-laden air being drawn into a dehumidifier where the air passes across a refrigerated coil. The air is rapidly cooled below its dew point, condensing the water vapour and recovering its latent heat energy for re-use. The cooled air is then passed across the condenser where it is reheated and returned to the served area at the required lower relative humidity
Dry air is a laboratory phenomenon. Atmospheric air will always contain moisture, often in quantities that prevent natural ventilation from providing an effective answer to drying buildings. Whether it be during construction, after fire or flood damage or even after a period of disuse, moisture will build up within buildings, often with damaging consequences. These problems can be disguised by the use of heat or ventilation (when the weather is occasionally suitable) but are unpredictable, slow, and potentially energy inefficient.
Dehumidifiers are the only method of positively removing moisture in a controllable, efficient manner from a space, and at a speed that can be dictated to suit the application. During building construction, dehumidifiers can be used to accelerate the rate of drying wet processes such as concrete floors and plaster, not only allowing the construction work to proceed more rapidly, but in a way that ensures the drying will not encourage cracking and distortion. Further, concrete floors that are dried by dehumidifiers will always settle at the correct moisture content.
