3 Product Features Models Floor Mounted Active Beam The Floor Mounted Price Active Beam,, is an exposed, perimeter unit suitable for office spaces, schools, hotels, lobbies, or any application where occupant comfort demands are high. The upper portion of the induces room air to pass through a heat exchanger and mix with the fresh ventilation air from DOAS (Dedicated Outdoor Air System). The mixed air is then discharged evenly from the lower portion of the across a louvered or perforated face at a low velocity. During cooling, the cool air flows down to the floor and spreads across the occupied space. During heating, the warm air rises and will heat the perimeter. The can be used as a standalone product or can be connected in series, by interlocking plenums, with other units to create a continuous look.
