This modern adsorption dehumidifier is the ideal drying device in unheated (cold) rooms and generally at low ambient temperatures. This is where it shows its strengths, as conventional dehumidifiers with refrigerant and compressor technology are very inefficient at temperatures of 1°C ~ 15°C. Thus, the WDH-DS3 still dehumidifies up to a strong 9 L/D at temperatures around approx. 8°C and 80% r.l. ! The adsorption dehumidifier impresses with a very clear control panel with LED display, three air circulation levels, standard mode, auto mode, dry mode (turbo), continuous operation, air purification mode as well as timer function ! The unit offers high quality at a good price-performance ratio with easy handling !
