General information

Application

Active chilled beams for installation into ceiling bulkheads, preferably for room heights up to 4.00 m
Especially for hotel rooms and hospital wards
Demand-based supply of primary air or supply air

The additional thermal load is dissipated by water

2-pipe or 4-pipe heat exchangers enable good comfort levels with a low conditioned primary air flow rate
Energy-efficient solution as water is used for heating and cooling

Special characteristics

One-way air discharge
Horizontal heat exchanger as 2-pipe or 4-pipe system
Connections on the rear of the device

Therefore with short cable runs
Connection possible in the corridor area

The supply air spigot is extendable (sliding) to compensate for structural tolerances
Nominal sizes are based on the basic dimensions
Integrated volume flow controller as an option

Nominal sizes

1000, 1125, 1250 mm

① Primary air spigot

③ Fixing bracket
④ Supply opening
⑤ Water connection (tube diameter 12 mm)
⑥ Heat exchanger

Active chilled beams provide centrally conditioned primary air (supply 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. This induces secondary air from the room. The secondary air flows through the horizontal heat exchanger. There it is heated or cooled as required. Primary air and secondary air are mixed in the mixing chamber and flow horizontally into the room as supply air.
