Description

Active chilled beams bring fresh air (primary air) into a room from a centralized ventilation system, using heat exchangers to preserve indoor air quality and also to cool and/or heat it. Primary air enters the mixing chamber through nozzles. As a result, secondary air is drawn through the face of the beam, passing through the vertically mounted heat exchangers and into the mixing chamber. In the chamber, primary air is mixed with cooled secondary air, and then supplied horizontally through slot diffusers. There are eight models of different lengths, each of which can be equipped with three types of nozzles. This allows you to select the desired option that optimally meets the requirements for air flow and cooling capacity with low pressure drops and low noise characteristics.
