MyVallox 245 CFi enthalpy

MyVallox 245 CFi enthalpy

The MyVallox 245 CFi with an enthalpy cell is suited to large detached houses of less than 400 m2 and various business premises, such as schools, day-care centres and offices. The modern ventilation unit has integrated humidity and carbon dioxide sensors that boost and reduce ventilation automatically according to indoor air quality. An optional VOC sensor also reacts to indoor VOC levels.

The enthalpy cell recovers both heat and moisture from extract air and transfers them to supply air. This helps maintain pleasant indoor air, reduces excessive dryness and supports energy-efficient ventilation even in large spaces.

The unit is equipped with constant flow fans that compensate for pressure differences and keep air flows in balance in windy conditions, tall buildings, during HR cell defrosting and regardless of the heat recovery bypass status. The constant flow feature also compensates for separate extractions, ensuring optimal ventilation as conditions change. Litre-based air flow adjustment directly from the controller makes the installer’s work easier.

MyVallox 245 CFi can be controlled with MyVallox Touch or MyVallox Control, through the home network or MyVallox Cloud service, and connected to building automation via Modbus RTU. A unit registered with the cloud service is updated automatically.

The unit’s specific fan power is only 0.7 kWh/m3/s, and its high annual efficiency rate helps save energy. Automatic heat recovery bypass with cold recovery utilises the coolness of summer nights, while partial bypass keeps the supply air temperature even and pleasant in all seasons.
Including accessories: Condensing water seal Vallox SilentKlick.
