Tate Access Floor’s In-Floor Active Chilled Beams offer the benefits of an underfloor air distribution with the efficiency of water-based heating and cooling. Water pipes pass chilled or hot water through a heat exchanger, or beam, which then delivers heated or cooled air to a space. Because it runs under the floor, this system avoids potential complications from overhead chilled beams, including leaking water lines and latent loads producing condensation. In-Floor Active Chilled Beams need fewer visible diffusers in the perimeter zone, and instead use segmented or continuous linear grills. tateaccessfloors.com
