Product details
The LWZ 170 E plus central ventilation system with heat recovery is specifically designed for use in large detached houses and small commercial properties. The slow-turning, highly efficient fans guarantee a high air flow rate with significantly reduced noise levels. The air volume can be conveniently adjusted in three stages via a remote control (essential accessory). Up to 90 % of thermal energy is recovered from the extract air by an efficient cross-countercurrent heat exchanger. The optimised heat exchanger and minimisation of the internal pressure drop enable very quiet and efficient operation. An integrated bypass prevents unwanted heat transfer on hot days.
