More about Helios FDR
Damp rooms, such as cellars, washrooms and garages, are a major problem and often difficult to get under control. With the FDR differential humidity control system, Helios offers an advanced and flexible solution that combines a control system and freely selectable fan to solve the problem both sustainably and efficiently. FDR continuously measures the temperature and humidity inside and outside. The intelligent control system then decides whether there are suitable conditions for ventilation, so that optimum and resource-saving operation is always guaranteed.
