KWL® systems with heat recovery are the most energy-efficient ventilation solution for residential and commercial applications. They extract heat from the polluted room air and transfer it to the fresh outdoor air. The heating costs are reduced by a third, a healthy room climate arises.
The new Helios KWL® ceiling and wall units also have optimized efficiencies and an integrated web server “easyControls” that allows control via laptop and smartphone. The new, unified clear design symbolises by the side-mounted design elements the heat exchanger function (absorb and release heat).
