The condenser tumble dryer dehumidifies the air when the evacuation of the waste air from the dryer through a wall opening or window is not possible. The Hose is simply fastened to the dryer, such that the steam is directed through the hose into the container, where it is turned back into water. The Large volume (8 litres) enables the accommodation of a large volume of evacuated moisture, which condenses to water due to the deep-frozen accumulators. The Container can be easily emptied after use. The condenser fits all conventional tumble dryers.
