Constantly fresh: System combination with continuous supply of fresh air

Our controlled residential ventilation units always ensure a comfortable indoor climate and high air quality, whether in new or existing buildings, whether centralized or decentralized. Our systems offer the right solution.

Seamless system integration with Vitoair FS mechanical ventilation systems

Vitoair FS mechanical ventilation systems can, for example, be combined seamlessly with a Viessmann Vitocal heat pump. They can be extended with a photovoltaic system and a power storage unit, enabling operation almost completely independently from the public grid.
