Krueger active chilled beams features the aerodynamic properties of Krueger ceiling diffusers and benefit from the use of using hydronic coils and air to reduce energy consumption associated with removal of sensible thermal loads. The primary air is supplied to the chilled beam subsequent to it being discharged through a series of nozzles located along the length of the beam. The nozzles inject the primary air into the mixing chamber at velocities capable of inducing room air through two coils and where it mixes with the primary supply air. This mixture of air is then discharged into the space through the ceiling slot diffusers. This provides high cooling outputs with low amounts of primary air. The reduced volume of air results in the reduction of the air handler capacity and size, smaller duct sizes, and the overall energy consumption. The BAL-12s are offered for both cooling and heating, and lengths from 2’ to 10’. They can be easily integrated into different grids styles within a suspended ceiling or even in drywall ceilings.
