TROX DID601 and DID602 series active chilled beams use a combination of primary air and chilled water (above the room dew point) to provide sensible cooling to the space. They combine the airflow characteristics of ceiling diffusers with the energy saving benefits of heat absorption using chilled water.

Primary air is ducted to the upper air chamber via a side or end inlet. The primary air is then discharged via nozzles to a lower section containing a 2 or 4 pipe heat exhanger coil. This causes room air to be induced, via the central perforated face panel, up and through the heat exchanger coil. The cooled (or heated) room air is then blended with the primary air before the mixed air is delivered into the room via single (1-way) or dual (2-way) discharge slots.

The beam uses the primary air energy to induce air through the coil, therefore no moving parts, fans or motors are required within the beam.

Dependent on the coil configuration and the temperature of the primary air from the air handling unit, the DID601 and 602 series beams can be used for cooling and/or heating.
