Specification text

Active chilled beams of type DID-F with two-way air discharge are suitable for freely suspended or direct installation below the ceiling slab and offer optimum comfort thanks to the ideal discharge angle and maximum induction. The active chilled beam can be used on its own or as the perfect extension to a concrete activation since it has a positive impact on the thermal output supplied to the room. This air-water system does not require a false ceiling, and the maximum installation height should preferably not exceed 4 m. 3 different assembly kits are optionally available for fixing, but with 4 different assembly options, and these are installed using standard fixing materials. This enables fast, straightforward installation, depending on the structural conditions. The sizing of the technical data can be varied by choosing one of four possible nozzle sizes. The nozzles are punched into the nozzle plate and are non-combustible. The primary air flow rate can be low for hygiene and energy reasons. Working in conjunction with the horizontal heat exchanger, this enables the dissipation of large heating and cooling loads. The water connections positioned on the narrow side are optionally available as plain tails, G½" external thread with flat seal or G½" union nut. The primary air connection is on the same connection side as the water connections and is available with a nominal diameter of 125 mm, 160 mm or 200 mm. This allows for direct connection of devices e.g. via the corridor side, avoiding complex ducting within the room. Circular ducts in accordance with EN 1506 or EN 13180 can be installed directly. Owing to the decreasing apertures of the induced air grille, the DID-F fits perfectly into its surroundings. The optional air control blades allow for air distribution to be adjusted manually at any time.

Special features

• The optional duct covering enables central installation of the active chilled beam even with a large room depth, whereby the necessary supply lines for air and water are provided with identical covering
• Manually adjustable air control blades for air direction control enable reduction of vh1 and vl velocities in the occupied zone
• Horizontal heat exchanger as a 2-pipe system and, for direct installation below the ceiling and a maximum installation height of 4 m, also as a 4-pipe system for heating and cooling
• Internal nozzle plate with non-combustible punched nozzles
• Water connections at the narrow side, Ø12 mm Cu pipe with plain tails, with external thread, G½", flat seal or union nut, G½", flat seal
