Type DID642

Super flat active chilled beam with two-way air discharge and horizontal heat exchanger, suitable for grid ceilings with grid size 600 or 625

Active chilled beam for heating and cooling, with 2-pipe or 4-pipe heat exchanger, for integration with various ceiling systems

  • Preferably for room heights up to 4.0 m
  • High heating and cooling capacity with a low conditioned primary air volume flow rate and low sound power level
  • Five nozzle variants to optimise induction based on demand, including adjustable twin nozzles, i.e. one pair of nozzles with different diameters
  • Hinged, removable induced air grille in two designs


Optional equipment and accessories

  • Control package
  • Additional casing for both supply air and extract air, or for additional supply air
  • Supply air and extract air units upon request
  • Adjustable air control blades for air direction control
  • Heat exchanger powder-coated black
  • Powder coating in many different colours, e.g. RAL CLASSIC
  • With an extended border also suitable for freely suspended installation

Functional description

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 (five variants are available) into the mixing chambers; as a result of this, 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 horizontally through the supply air slots.

Set of air control blades

If a high cooling capacity is required in a very small space with active chilled beams, optional air control blades allow for adjusting the air discharge pattern such that the acceptable air velocity in the occupied zone is not exceeded. The airflow of each active chilled beam is spread and discharged according to the room geometry. If the use of a room changes, the air discharge pattern can be optimised by adjusting the air control blades accordingly.

  • It is possible to adjust several air control blades (i.e. a set of air control blades) together
  • For fine adjustment, the sets of air control blades can be disconnected from each other
  • To adjust a set of air control blades, use both hands to move the two outer blades of the set as required
  • Maximum possible adjustment is 45° to the right or left in steps of 15°
  • The blades are factory set to straight air discharge

If the air discharge is not straight, the water-side capacity will be slightly affected. The effects can be taken into consideration when the Easy Product Finder is used for sizing.

Installation into grid ceilings 00225859_0

Installation and commissioning

  • Preferably for rooms with a clear height up to 4.0 m
  • Flush ceiling installation
  • Lengths from 893 to 3000 mm, and widths of 593, 598, 618 and 623 mm, hence suitable for all ceiling systems, particularly for grid ceilings with grid size 600 or 625
  • Side entry primary air spigot
  • Active chilled beam has 4 suspension points for on-site installation (by others)
  • Installation and connections to be performed by others; fixing, connection and sealing material to be provided by others
  • Heat exchangers are fitted with water flow and water return connections at the narrow side


Installation into T-bar ceilings or continuous ceilings

  • To avoid too much load on the ceiling, the suspension points should be used

Mixed flow

The supply air is discharged from the diffuser into the space with a velocity between 2 and 5 m/s. The resulting air jet mixes with the room air, ventilating the entire space. Mixed flow systems typically provide a uniform temperature distribution and air quality within the space. The originally high velocity of the turbulent air jet decreases rapidly due to the high induction levels of mixed flow systems.
