For optimum comfort, the relative humidity (RH) in your home should be between 40% and 60%. If the outdoor temperature is low, the relative humidity can fall below 40%. The Evap Pro humidifier is automatically activated if the outside temperature drops below 12 °C. The humidifier automatically humidifies the air that has been filtered and has passed through the heat exchanger in the ventilation unit. This guarantees even greater comfort. This is particularly important during the winter months, when the indoor humidity level often drops. The Evap Pro maintains the optimum humidity level in your home. Because the humidifier is connected to the water supply, there is no need to fill it with water by hand.
It works based on the natural water evaporation process (adiabatically). The dry air flows through a water-absorbing glass fibre matrix and absorbs the water vapour from the humid surface.
