The DHK air dehumidifier is an easy-to-use machine with high efficiency, ready for immediate use, in an aesthetic and sound-absorbing housing. It is equipped with a control system, a water tank and an air filter. Thanks to the built-in hygrostat and automatic defrosting function, costs of energy consumtion are similar to those of a domestic refrigerator. Wheels, handles and low weight make it a mobile machine and it can be easily moved to any place. DHK-14,18 dehumidifiers have housing made of impact-resistant plastic, and DHK-28E and DHK-38E dehumidifiers are made of stainless steel. In addition, the DHK-14 and DHK-18 models have two fan operation modes, an additional carbon filter and filter contamination indicator. These are quiet and aesthetic machines, dedicated to places where people are present (such as museums). All DHK dehumidifiers are equipped with both a container and a hose for draining the condensate.
