DIAP passive chilled beam

The passive chilled beam consists of a finned tube heat exchanger that is surrounded by a frame and covered to the room side with a front panel (generally a perforated panel with square perforation). The passive chilled beam is used to remove high interior heating loads and is available in the widths 300, 450 and 600 mm. The length can be adjusted to individual needs within the range of 1200 mm to 3600 mm in steps of 300 mm. The standard frame height is either 157 mm or 266 mm. The visible front panel as well as the exterior frame surfaces are powder-coated in RAL 9003.

Function and effect

Passive chilled beams work in accordance with the principle of free convection. Warm room air in the ceiling area is cooled due to the heat exchangers blades and flows as a result of the higher density into the lower area of the room.
Air flow velocity and cooling performance are mainly influenced by the following parameters:

The passive chilled beam can be used in almost every kind of room and is also well suited for subsequent installations.
