Fair.AIdH is new. What has remained is the proven infrared heating principle, which is so superior in halls. As with all hall heating systems from KÜBLER, the heat is generated according to the solar principle: radiant energy acts directly on people, floors and objects - without heating the entire air volume of the hall. In this way, energy losses due to rising warm air are almost completely reduced, while at the same time a high level of thermal comfort is created in the area of use. No swirling up of dust, no draughts, no cold feet.
