General Information

Application

Active chilled beams suitable for direct assembly below the ceiling slab or freely suspended in the room
A suspended ceiling is not required, which means that these devices can ideally be combined with component activation
For an installation height up to preferably 4 m, the room height can be greater
Heating with the DID-F is only possible if the devices are installed directly below the ceiling slab and the installation height is ≤ 4 m
Adjustable air control blades allow for later manual adjustment of the air discharge direction

Active chilled beams provide centrally conditioned primary air (fresh air) to the room and use heat exchangers for additional cooling and/or heating. The primary air is discharged through nozzles (4 different variants) into the mixing chamber; as a result of this, secondary air is induced. Secondary air (room air) is induced via the induced air grille and passes through the horizontal heat exchanger, where it is heated or cooled. Primary and secondary air mix and are then supplied to the room laterally through the supply air slots. The DID-F fulfils this function without a suspended ceiling and can either be installed directly under the ceiling slab or suspended in the room.

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

DID-F with duct connection

DID-F with duct connection

Application

Duct covering provides a visually attractive covering for the supply lines provided by others if the DID-F is assembled deeper in the room
Duct coverings can be ordered in the lengths 200 – 2900 mm
Duct covering can be integrated into the room so that it is visually inconspicuous, as it has a similar geometry to the DID-F

Materials and surfaces

Duct covering made of galvanised sheet steel
Exposed surfaces are powder-coated pure white (RAL 9010) or in any other RAL CLASSIC colour

Water connections Ø12 mm pipe, plain tails
Water connections A1 G½" external thread and flat seal Water connections A2 G½" union nut and flat seal

Application

Water connections form the interface between the active chilled beam and the duct network provided by others
To find the best form of transition for the project, there are 3 different water connections available
Ø12 mm Cu pipe with plain tails – connection is particularly suitable for a direct connection to the copper pipe network; all the usual connection methods can be used here such as soldering, press-fit and push-fit
A1, G1/2" external thread and flat seal – water connection is particularly suitable for connection with union nuts, which creates a detachable connection
A2, G1/2" union nut and flat seal – this is also a detachable solution and is particularly suitable for direct connection of control valves and shut-off valves
All connections provided by others must be tested under pressure once installed and checked for tightness

Nominal sizes
