KWL ventilation systems with heat recovery

A comfortable climate and energy saving. For low-energy / passive house standard, multi-storey buildings and commercial applications.

The next generation

The compact wall units KWL EC 200 W to KWL EC 500 W and the ultra-flat ceiling units KWL EC 220 D and KWL EC 340 D are equipped with Helios easyControls as standard. They therefore redefine the standard for the operation of KW devices. Thanks to the integrated web server and LAN connection, the ventilation devices can be integrated into the PC network and conveniently controlled via a user interface in the web browser using a laptop or smartphone – even over the Internet while you're on the go. Building control system interfaces and optional controls and air quality sensors provide additional options. The clever, modular design of the appliances allows for custom configurations according to the property requirements. The new KWL EC "S" range for standing, space-saving floor installations is available with ventilation system performances of 800 to 2600 m³/h. Ideal for use as central systems with heat recovery in residential, commercial and industrial applications. Certified according to the passive house standard and including special control technology for constant volume regulation or constant pressure regulation. Optionally with built-in PWW heat register.

KWL Periphery

Just as important as the KWL ventilation unit is the suitable system-periphery in the building.
Perfectly adapted accessories, air distribution systems for extract-, supply-, intake and exhaust air as well as undersoil heat exchanger ensure the trouble-free and energy-saving operation of the KWL system.
