Most construction work uses large amounts of water, which remains in walls, floors and ceilings, and which must be removed to continue the work.
In subsequent finishing works, there is also the need to accelerate the process of drying plaster walls, plasterwork, surfaces after painting, etc. In the above mentioned cases, ventilation of rooms in non-winter periods and ventilation with heating in the winter period are usually used. However, both methods are not effective enough, and sometimes do not produce any results.
In spring and autumn, the outside air is cool and humid. The method of ventilating and air heating, which is used in winter, is uneconomical and ineffective. The best results when dehumidifying a building can be achieved by using dehumidification units. They condense the moisture contained in the air, allowing continuous absorption of moisture from walls, ceilings and floors. The unit should be placed in an enclosed room to restrict the access of humid air from the outside.
