Adsorption dehumidification technology is the most efficient dehumidification method. It is characterized by high efficiency and durability. Adsorption, washable drying rotor is the most element of the device. It can work 10-12 years, depending on operation conditions. Humidity that is removed from the air is adsorbed at the rotor surface and it does not interfere with its structure, so the rotor maintains its drying features for a long time.

within the full range of humidity (0 to 100% RH) and very wide temperature range, including temperatures below zero (-25C to +40C). Using adsorption dehumidifiers by LEWACO gives the option to achieve very low dew points (e.g. DP=-20C, DP=-25C for special versions).

Another advantage of adsorption dehumidifiers that is a result of their amazing durability is the possibility to achieve the effect of appropriate dehumidification with minimized amount of air necessary for this process. As a result, ventilation ducts and sizes are smaller.

Adsorption dehumidification basing on LEWACO devices can be used in all weather conditions, with all humidity levels, and guarantee efficient solution of the problem of humidity for long years.
