Calorex Porta-Dry 300

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.

Porta-Dry dehumidifiers are specifically designed for mobile dehumidification and are built to withstand the rigours of construction sites and hire-related wear and tear. They are supported by a nationwide service network and technical support team to ensure the correct product is selected for your needs.
