Decentralized ventilation units make continuous room ventilation possible while at the same time preserving heating or room heat. The room air is transported out of the room with the exhaust air volume flow, the heat is transferred in the decentralized ventilation unit to the supply air volume flow, which transfers fresh outside air and the transferred heat back into the room air.
Decentralized ventilation units are particularly characterized by their flexible installation and low cost. These ventilation units can therefore also be easily retrofitted, e.g. during renovation work and when the value of a property is increasing. If all costs are taken into account, the use of a decentralized ventilation system is usually more cost-effective than the installation of a central ventilation unit. Another advantage of decentralized ventilation systems is the ease of maintenance. These systems are easy to maintain, repair and clean.
