LWZ 170 E PLUS Central Ventilation System

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.

The LWZ 170 E PLUS uses a cross current design to effectively recover the heat in the air indoors as it exchanges this with fresh air from outdoors. The LWZ 170 E PLUS is ideal for low energy buildings and passive homes.
