New I-tec fan from Internorm

Cluster-News: May 2015

With the new I-tec fan from Internorm, indoor spaces are ventilated in a demand-based, convenient and energy efficient manner. The ventilation system is fully integrated in the structure of the window frame. With the I-tec system ventilation can be controlled individually for each room. The all-glass window system PANORAMA HX 300 enables the window frames to be hidden almost entirely in the wall or floor, thereby permitting large-scale, continuous glazing (single-glass surfaces of up to 10.5 m²).
