Type DID-R

Active chilled diffuser with radial air discharge, 600 or 625 mm nominal width, vertical heat exchanger and condensate drip tray

 

Active chilled beam for heating and cooling, with 2-pipe or 4-pipe heat exchanger, for integration with various ceiling systems. The condensate drip tray is useful if the temperature temporarily falls below the dew point.

  • Preferably for room heights up to 4.20 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
  • Circular or square diffuser face


Optional equipment and accessories

  • Control package
  • Casing powder-coated black
  • Heat exchanger powder-coated black
  • Powder coating in many different colours, e.g. RAL CLASSIC or NCS

Application

  • Active chilled diffusers of Type DID-R for the integration into various ceiling systems, preferably for room heights up to 4.20 m
  • Particularly suitable for continuous ceilings and for grid ceilings with grid size 600 or 625
  • 2-pipe or 4-pipe heat exchangers enable good comfort levels with a low conditioned primary air volume flow rate
  • Energy-efficient solution since water is used as a medium for heating and cooling
  • Active chilled diffuser with radial air discharge

Special characteristics

  • Radial air discharge
  • Vertical heat exchanger as 2-pipe or 4-pipe system, with condensate drip tray that is useful if the temperature temporarily falls below the dew point
  • Water connections at the side, Ø10 mm Cu pipe with plain tails

Variants

  • DID-R: Circular construction, Ø598 mm
  • DID-R-Q: With square diffuser face (593, 618, 598, or 623 mm)

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 chamber; as a result of this, secondary air (room air) is induced via the induced air grille and passes through the vertical 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 horizontally and radially.

Active chilled diffusers of Type DID-R, with radial air discharge and high thermal output, providing high thermal comfort levels.

For installation flush with the ceiling, preferably in rooms with a height up to 4.20 m.

The units consist of a casing with suspension points, a spigot, and a vertical heat exchanger with condensate drip tray.

Nozzles in three sizes to optimise induction based on demand.
