DID-F

Compact active chilled beam with two-way air discharge, can be easily combined with other systems for room temperature control, such as concrete core activation

Active chilled beam for freely suspended installation, no suspended ceiling required

Inexpensive solution for refurbishments and spaces of low floor-to-ceiling height
Compact ventilation system for room temperature control with open ceiling design
Flexible application – installation directly below the ceiling slab or freely suspended in the room
Ducts and water pipes in the room can be short since connections on the narrow side of the beam allow for air and water being provided from the corridor side
Manually adjustable air pattern with optionally available air control blades
Reduced height thanks to horizontal heat exchanger and high thermal load dissipation with water

General information

Application

Active chilled beams for direct installation 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 concrete core activation
Preferably for installation up to 4 m high, even if the room is higher
Heating with the DID-F is only possible if the device is 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
Preferably with a 2-pipe heat exchanger for cooling; with direct installation below the ceiling slab, a 4-pipe heat exchanger for cooling and heating is an option
Good comfort levels with a low conditioned primary air volume flow rate
Energy-efficient solution as water is used for heating and cooling

Special features

The optional duct covering allows for installation of the active chilled beam in the middle of the ceiling even if a room is large, as the same covering is used for ducts and water pipes to create a uniform look
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 G½" external thread and flat seal, or with G½" union nut and flat seal

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 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 through the supply air slots at the side. 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.

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 concrete core activation since it has a positive impact on the thermal energy supplied to the room. This air-water system does not require a false ceiling, and the installation height should preferably not exceed 4 m. 3 different installation kits are optionally available for fixing, but the chilled beam can also be fixed without an installation kit, using standard fixing materials. This enables fast, straightforward installation, depending on the structural conditions. Sizing 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. Together 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 beam, e.g. from the corridor, avoiding complex duct and pipe layouts in 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 allows for installation of the active chilled beam in the middle of the ceiling even if a room is large, as the same covering is used for ducts and water pipes to create a uniform look
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 G½" external thread and flat seal, or with G½" union nut and flat seal
