Active chilled beam
Description
The OptimAir is a two-way induction type active chilled beam,
integrated in false ceilings. OptimAir is primarily designed to
ventilate, cool and/or heat buildings, where a comfortable
climate and individual room control is needed. OptimAir is
now available with two plenum box options for a medium
(M) or a medium-large (ML) airow. We also oer two heat
exchanger options to best suit the cooling and/or heating
demand of the air-conditioned zone. OptimAir is designed to
t most types of suspended ceiling frameworks on the market
with a standard width of 600 mm.
Air duct connection: OptimAir M and ML are available with
with either one or two air duct connections on the side of the
chilled beam. The suggested air duct quantity and dimension
depends on the length, primary airow and pressure of the
selected chilled beam.
Function
The primary air from the supply air system is connected to
the plenum box and distributed through specially shaped
nozzles. As the air is discharged through the nozzles, the high
velocity air jets above the coil create a low-pressure zone. This
low-pressure zone draws ambient room air through the coil,
and as it passes the coil ns it is conditioned (cooling - heat-
ing), according to the water temperature owing through the
coil. The conditioned air then mixes with the air jets (venti-
lation air, humidity control) before it is discharged back into
the occupied space. The conditioned/mixed air discharged
along the ceiling provides an optimal Coanda eect which is
always the objective when the occupied zone requires low air
velocities.
Variable nozzles
As standard, OptimAir is supplied with variable nozzles. This
is a unique, elegant and exible feature, which simplies
the adjustment of the nozzle positions on either side of the
plenum box to set the required airow without modifying
the primary air pressure. With the use of an Allen wrench the
airow can be adjusted in ve steps on each side of the chilled
beam, by covering and uncovering the nozzles. This mechan-
ical solution features some very clever engineering, and was
designed to stand the test of time. The requested airow can
be selected in our selection software, and is factory pre-set
and can also easily be changed on-site.

AirFlex
- Less risk of draft
- Shorter throw length
- Individually adjustable
AirFlex- adjustable air deectors
OptimAir is equipped with AirFlex air deectors, which can
be manually and individually adjusted on each side of the air
slots, as a standard option. AirFlex allows the operator to easily
adjust the direction and throw distance of the discharged
conditioned air. With the ne-tuning capabilities of the
AirFlex deectors, in combination with the variable nozzles, a
highly exible, pleasant and draft-free indoor climate is easily
achieved.
Materials
The connection and plenum air box are made of galvanized
steel. The visible front plate and side panels are aluminium
powder coated in standard white RAL 9003 colour. The heat
exchanger consists of copper and aluminium. The AirFlex air
deectors are made of Polyamide plastic. Square or circular
perforation as a standard option. Rubber sealing on the air
connection.

Mounting instructions
The length and width of OptimAir is designed to t in most
T-grid ceiling frameworks. The units are delivered with four
factory mounted suspension elements (one in every corner),
which can be adjusted separately in four directions. The duct
connections are supplied separately in 100 or 125 mm dimen-
sions. The connections are mounted directly on the plenum
box and are locked with a screw.

Maintenance and installation guide
Maintenance
The perforated front panel of OptimAir can be folded down
allowing easy access for maintenance. The plenum box and
the heat exchanger have to be cleaned by carefully using a
vacuum cleaner so that the aluminium ns and the copper
tubes are not damaged. The parts that are out of reach for the
vacuum cleaner have to be wiped o with a soft cloth. If requi-
red, mild preferably neutral cleaning detergent could be used.
The electrical parts have to be maintained in accordance with
the relevant prescriptions. The points of connection/shock
protection and the functional ability of the components must
be checked. The maintenance operation has to be carried out
at least twice a year.
