Air aggressiveness is very important to a dehumidifier as it typically operates in a chlorine or salty environment. Microwell ensures probably the highest protection of the whole machine and its components. The coils are from anodized aluminum fins coated with GoldFin finish and copper pipes finished with zinc coating for a maximum protection against aggressive substances present in pool’s air. All metal parts are galvanized and powder coated, where needed stainless steel or titanium of highest pureness are used.

Humidity is not an enemy when controlled but can cause serious troubles otherwise. Ideal humidity for pool or spa users is when they feel comfortable. This feeling is achieved by a relative humidity from 55% to 65%. Humidity above 70% is detected by condensation on windows and walls and the humidity continuously deteriorates the pool or spa environment. It is also a perfect environment for mould and bacteria to grow. Humidity lower than 45% actually causes a reversed problem to bathers in the form of dry feeling and possible harm to mucous tissue. The innovative series of Microwell dehumidifiers keep the humidity at ideal 55%-65%.
