Commercial and industrial drying DH60AHP Calorex

Drying by dehumidification is a low maintenance way to provide efficient moisture removal while minimising the power consumption, cost and risk of product damage. Calorex dehumidifiers provide you with a high quality finished product and costs less to operate than other methods of drying.

Air is recirculated within the chamber by a set of fans positioned above a false ceiling – the velocity past the product being critical to the drying speed. The temperature of the chamber is increased to speed the release of moisture from the product. The higher the temperature the quicker the drying process. The moisture released by the product is extracted by the dehumidifier. The heat pump dehumidifier converts the latent energy into heat which is returned back into the drying chamber.

This reduces the energy required to maintain the operating temperature. The condensed moisture is rejected to a waste water drain.
