Function
The CBQ unit is an active chilled beam for exposed

The supply air flow of the chilled beam nozzle jets is
dependent on effective length, nozzle type and static
chamber pressure.
The primary supply air enters the plenum of the
active chilled beam, from which it is diffused into

The primary air flow rate of each beam is adjusted
using the Halton Air Quality control unit during the
installation and commissioning. There is no need to
change or plug nozzles of the chilled beam.
Halton Air Quality control also allows increasing the
air flow rate of a chilled beam - e.g., to meet the
ventilation requirements of meeting rooms (up to
4 l/s per m2, below 35 dB(A)).

Lighting
Luminaires for CBQ chilled beams are especially
designed high specification recessed direct/indirect
luminaires for office applications. The luminaire is
designed to suit chilled beam aperture, providing
direct/indirect lighting to help meet the Office Lighting
Guide LG7 (UK) requirements. Lights are installed and
tested in the factory. An extra cable with or without
plug is delivered upon request. Standard plug types
are Schuko, Enstonet and Wieland.
Lights are manufactured from steel, power coated
to match the required finish. Xenoptic satin louver
is retained by shootbolt spring fixings. All luminaires
come complete with T5 triphosphor lamps with the
option of high output or high efficiency.
High frequency control gear DSI, DALI or 1…10 volt
dimmable gears are available.
As an option there is also available self-contained
emergency lights or central battery/static inverter
conversions available, with or without self test
