Efficient and energy conscious
1-compartment ventilation solution

One-compartment heat recovery system that fits in an existing Ø105 mm hole, allowing the unit to ventilate and exchange air while recovering heat with the ceramic core.
DUKA One Pro 25 S Wi-Fi is a Ø100 version that has a shorter core and motor so the wall thickness can be as thin as 165 mm. With the smaller hole and shorter core, the unit can also fit in a 150×150 mm duct, for example.

The DUKA One is a complete solution that is installed in a facade and immediately improves the indoor climate. The system's low-energy fan operates alternately in supply and extract mode. The heat from the home is transferred to the ceramic exchanger in the unit during the exhaust mode. When the fan reverses and starts blowing air into the home, the heat is recycled by preheating the outdoor air as it passes the exchanger. The solutions can be controlled according to many different needs, individually or in series.

Wi-Fi control allows you to quickly and easily get multiple Wi-Fi devices to talk and work together. With Wi-Fi control, you can also set the device to your personal needs, including a weekly programme.
