DID-F 

Compact active chilled diffuser with two-sided discharge can be easily combined with other systems for room temperature control such as concrete core or component activation


 

Active chilled beam suitable for freely suspended assembly or installation without suspended ceiling

  • 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 – assembly directly below the ceiling slab or freely suspended in the room
  • Short routes due to the connections being positioned on the narrow side with ductwork from the corridor side
  • Individual, manually adjustable air distribution with optionally available air control blades
  • Reduced height thanks to horizontal heat exchanger and simultaneous high thermal load dissipation via the heat transfer fluid water

 

 


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
  • 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 also possible
  • Good comfort levels with a low conditioned primary air volume flow rate
  • Energy-efficient solution as water is used for heating and cooling



Special characteristics


  • 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

  • FUNCTION
  • TECHNICAL DATA
  • QUICK SIZING
  • SPECIFICATION TEXT
  • ORDER CODE

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

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
