More comfort. More efficiency. More possibilities.
The KWL EC 70 brings fresh air even to small residential units – easily, energy-efficiently and with outstanding flexibility. As the ultimate all-rounder, it adapts to any structural condition with three installation options and can also ventilate additional rooms, such as internal bathrooms, via a second room connection.
With an air flow of up to 70 m³/h, it reliably delivers optimal air quality and is particularly easy to install thanks to only two core drill holes for the outside air and exhaust air ducts.
Three times the first choice.
- Surface-mounted installation
The KWL EC 70 is available for surface-mounted installation, making it ideal for renovations of existing buildings. Quick, effortless and perfect for the supply and extract ventilation of individual rooms.
- Partially wall-integrated installation
Partially wall-integrated, the ventilation unit disappears into the external wall, leaving only the stylish inner panel visible. This solution is perfectly suited for new builds and comprehensive energy-efficient renovations.
- Partially wall-integrated installation with second room connection
The KWL EC 70 offers even more possibilities with a second room connection for supply/extract air, which can be used to ventilate a second room in addition to the installation room.
Centralised? Decentralised? Both!
One device – many possibilities! Discover just how versatile the KWL EC 70 really is.
Ventilation at peak efficiency.
- High heat recovery rate of up to 85 % for energy-efficient ventilation.
- Heat exchanger options: cross-counterflow or enthalpy heat exchanger for additional moisture recovery.
- Demand-driven sensor technology: an integrated humidity sensor is included as standard, additional sensors for demand-driven operation are available as optional extras.
- Extremely fast and super easy commissioning thanks to the KWL EC 70 software via USB connection.
Discreet or invisible: the outside and exhaust air connection.
The stainless-steel facade panel combines an elegant design with excellent performance: corrosion-resistant, available in three surface finishes and designed for quick installation. If you prefer a fully concealed solution, installing the stainless steel grille in the window soffit provides an inconspicuous option, seamlessly integrating it into the architecture. Both options offer reliable, clearly separated outside and exhaust air routing.
