General Information
Application
- Active chilled beams of Type DID642 for the integration into various ceiling systems, preferably for room heights up to 13 ft
- Particularly suitable for grid ceilings with grid size 24 or 25
- 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 for heating and cooling
- Adjustable air control blades (optional) allow for the manual adjustment of the air discharge direction
Special characteristics
- Adjustable air control blades for air direction control
- Hinged, removable induced air grille in two designs
- Horizontal heat exchanger as 2-pipe or 4-pipe system
- Water connections at the narrow side, Ø0.5 in Cu pipe, either with plain tails or with external thread or union nut, G˝”, flat seal
- Internal nozzle plate with punched nozzles (noncombustible)
Nominal sizes
- 35, 47, 59, 71, 83, 95, 106, 118 in (118 only without additional casing)
Variants
Induced air grille
