Aluminum ventilation grill 754HEI

rectangularsquareexterior

The slat facade, System 754Hei, from MLL Hamburg, is a heatable facade system made of aluminium with a free ventilation cross section of 69%. This slat facade guarantees efficient air exchange even in very low outside temperatures. The slats are equipped with self-regulating heating elements and warm up depending upon the outside temperature. This prevents the slat surface from freezing over or being covered up with snow. The system 754Hei is equipped with a heatable Z-slat of the heavy series of type 050Hei. Fastening to a facade occurs via the Retaining rail 004. The facade system is used where it is necessary to guarantee free circulation in order to safeguard the weather protection system reliably from icing and icicle build-up, even in case of outside temperatures below 0° Celsius.
