Meet the Helios KWL EC 70 - A "single-unit" decentralised ventilation solution with a second room connection.

With the KWL EC 70, we can offer a unique decentralised ventilation solution that can do more: With only a single ventilation unit, this enables easy ventilation of an entire residential unit - ideal for small apartments, student accommodation or retirement homes. Thanks to the optional second room connection, the unit is super flexible, allowing for integrated ventilation of a wet room, effortlessly linked to the main unit. The KWL EC 70 impresses not only with its high energy-efficiency, but also with its ease of installation.

This A+ unit can achieve an incredible heat recovery efficiency of 85% with a maximum air flow of 70 m³/h. With flexible installation options - either surface-mounted or recessed into the wall - it easily adapts to the structural conditions on site.

Whether new build or refurbishment, the KWL EC 70 is the ideal choice for both applications. The surface-mounted version is particularly suitable for retrofitting in existing buildings thanks to its quick and uncomplicated installation - perfect for ventilating large individual rooms. For new buildings or major refurbishments, we recommend the partially wall-integrated solution. This disappears almost completely into the wall, leaving only the elegant inner panel visible, which blends discreetly into any interior design.

If, in addition to the main room, another room needs to be ventilated, the KWL EC 70 really comes into its own: the integrated second room connection can be used to efficiently ventilate bathrooms, for example. The humidity sensor integrated as standard automatically controls the ventilation output - for more comfort and maximum energy efficiency.

This sophisticated system solution is a one-of-a-kind and makes the KWL EC 70 the ideal choice for a wide range of living situations where previosly, there were only much more complicated options - simple, efficient and flexible.
