Type DID600B-L

Active chilled beam with two-way air discharge, horizontal heat exchangers and integral lighting, suitable for grid ceilings with grid size 600

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 4.00 m
  • High heating and cooling capacity with a low conditioned primary air volume flow rate and low sound power level
  • High comfort levels due to low airflow velocity in the occupied zone
  • Three nozzle variants to optimise induction based on demand
  • Side entry or top entry primary air spigot
  • Removable induced air grille


Optional equipment and accessories

  • Control system
  • Additional casing for extract air
  • Heat exchanger powder-coated black

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 into the mixing chambers; as a result of this, secondary air (room air) is induced via the induced air grilles and passes through the horizontal heat exchangers.

Primary and secondary air mix and are then supplied to the room horizontally through the supply air slots.

The DID600B-L doubles as a luminaire.

Installation details, Basic information and nomenclature

  • Installation details
  • Basic information and nomenclature

Installation and commissioning

  • Preferably for rooms with a clear height up to 4.00 m
  • Flush ceiling installation, particularly for grid ceilings with grid size 600
  • Choice of side entry or top entry primary air spigot
  • Lengths from 1493 to 3000 mm, and width of 593 mm, hence suitable for various ceiling systems
  • Installation and connections to be performed by others; fixing, connection and sealing material to be provided by others
  • Active chilled beam has 4 suspension points for on-site installation (by others)


Installation into linear beam grid ceilings

  • This is possible with the optional support angles (supplied separately)
  • No levelling required


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.

Heat exchanger

The maximum water-side operating pressure for all heat exchangers is 6 bar.

The maximum water flow temperature (heating circuit) for all heat exchangers is 75 °C; if flexible hoses are used, the water flow temperature should not exceed 55 °C. Units for other pressures and temperatures are available on request.

The water flow temperature (cooling circuit) should be at least 16 °C such that it does not permanently fall below the dew point. For units with a condensate drip tray the water flow temperature may be reduced to 15 °C.

Heat exchanger as 2-pipe system

Air-water systems with a 2-pipe heat exchanger may be used for either heating or cooling. In changeover mode it is possible to use all units within a water circuit exclusively for cooling in summer and exclusively for heating in winter.

Heat exchanger as 4-pipe system

Air-water systems with a 4-pipe heat exchanger may be used for both heating and cooling. Depending on the season, i.e. especially in spring and autumn, it may be possible that an office has to be heated in the morning and cooled in the afternoon.
