iQ Star LYRA chilled beam cassette
Product version and function
The LYRA chilled beam cassette is designed for
installation in false ceilings, and its dimensions fit a 600
mm false ceiling module.
This regards both its length and height, which means that
the product must be installed completely flush with the
ceiling. If the LYRA chilled beam cassette is equipped
with the accessory IQAZ-33, it can be freely suspended
from the ceiling.
The LYRA chilled beam cassette is equipped with comfort
control and has control equipment as an accessory. This
combination provides high flexibility for dimensioning
the indoor climate. The air flow can be adjusted with
levers (comfort control) by changing the number of
open nozzles in the air duct. This is easily done during
commissioning. The adjustable nozzles offer a choice of
air distribution options (1-way, 2-way, 3-way and 4-way).
This easy adjustment of air distribution and capacity
makes it easy to adapt the system to changing conditions.
On delivery, the standard beam has the maximum
number of nozzles open as default (nozzle 3). The LYRA
chilled beam cassette is equipped with Coanda Safety
Control (CSC). It can be varied between high effect mode
(front in lowest position) and normal effect mode (front in
highest position). CSC should be used with low air flows
to ensure that the air stream adheres to the ceiling. High
effect mode is obtained when the front is in the lowest
position. This mode should not be used below 50 Pa.
To achieve optimal air distribution into the room, and
full flexibility, tool free air flow adjustment is available
for each side. Levers located at each side enables fast
and simple air flow adjustment without the need for
additional tools.
From shut off position, low, medium and high setting
are available with 3 nozzle positions, boost setting with
4 nozzle positions and fixed boost setting fixed to 1
position.
Fixed boost setting requires no nozzle adjustment and
offers higher airflows at quieter noise levels.
Tool free nozzle settings for LYRA - low, medium and
high airflow.
Material and surface finish
The casing mainly consists of galvanized steel sheet. The
front panel has a white powder-coated finish. Standard
colour RAL 9010, equivalent to NCS 0502-Y, gloss level 30.
Tool free nozzle settings for LYRA - boost airflow.
Coil in copper with connector Øy = 15 mm and
aluminium fins. Max. working pressure 1.6 MPa.

Flow Pattern Control - FPC
The FPC (Flow Pattern Control) is a function that
makes LYRA highly flexible. It is the FPC function
combined with comfort control that gives LYRA its
unique characteristics. Fläkt Wood's FPC function allows
the air flow to be directed at different angles. It is very
easy to adjust and change the air flow direction.

set with comfort controls to the same nozzle on each side
of a size 120. This installation options provide an efficient
and comfortable air throughout the room.
The image below shows an installation where a high
airflow is needed. Comfort control is still set to the same
nozzle at each side, but the flaps set to 30 ° in the direction
of two neighboring beams.
Freely suspended
LYRA can be adapted for freely suspended installation.
This is done by ordering the accessory IQAZ-33, which
consists of a casing and a front plate adapter. This
accessory is fitted on the cassette while the cassette is
suspended from the ceiling.
In the freely suspended version, the air outlet is specially
designed to direct the air flow slightly upwards. This
reduces the air velocity in the occupied zone and ensures
that air from the room mixes with the chilled air before it
reaches the occupied zone.
Coanda Safety Control (CSC), Freely
suspended
Directing the air upwards also creates the Coanda effect
without needing to rely on nearby surfaces.
Coanda Safety Control (CSC)
Coanda Safety Control (CSC) is a function that maintains
the Coanda effect (adhesion of the air to the ceiling) while
simultaneously ensuring the highest possible cooling
power. This is done by adjusting the position of the front
panel.
At low flows and pressures, it may be necessary to adjust
the front panel to its highest position to keep the coanda
effect.
At high flows and pressure, the Coanda effect is easily
maintained, so the front panel can be set in its lowest
position, which increases the cooling and heating power
by approximately 5-10%.

A duct enclosure for concealing water pipes and air ducts
to the cassette unit is also available as an accessory with
three ranges of size:
• 30 to 50 cm
• 50 to 90 cm
• 90 to 170 cm
Suspension of the chilled beam
Installation with fastening bracket QFAZ-18
A suspension bracket facilitates the suspension of chilled
beams from the ceiling. Two brackets are used for each
beam. The brackets can be ordered in advance or along
with the chilled beam. The suspension brackets can be
fitted directly to the ceiling or onto channel support bars.
The chilled beam is simply attached by pressing it against
the bracket until it clicks into place. No tools are needed.
After this, the chilled beam can be adjusted lengthwise
by sliding the bracket along the beam's fastening points.
To adjust it sideways, slide the threaded bars along the
grooves in the bracket.
Installation of chilled beam with wire QFAZ-23-01-01
The chilled beam cassette can also be suspended with
wires. In this case, the beam's height is easily adjusted
with a stepless fastening device. This type of installation is
suitable for metal or concrete ceilings. Alternately, a wire
can simply be wound round a bar in the ceiling. A special
concrete fastener for concrete ceilings is included in every
kit.
With the lock system it is easy to adjust the height
installation of the chilled beam.

Criteria for reading cooling power tables
The cooling power of the supply air is based on the supply air being 10 °C cooler than the ambient air. The indicated
power for water are based on the CSC (Coanda Safety Control) function in high capacity setup mode. The effects for
other water flows are indicated in Fläkt Woods's product selection program. Contact our nearest sales office for further
information. The tables on this page are based on tests performed according to EN 15116. The method is used to compare
different chilled beams under equivalent conditions, and does not permit any difference in temperature between the
supply air to the beam's coil and the air 1.1 m above the floor. At low air flows, the CSC function should be set to its
highest position (Normal capacity setup) for optimal air flow characteristics.

The sound effect levels for different octave bands are based on computing the sound pressure level LA10, dB(A)
specified in Fläkt Woods's product selection program and the octave band corrections Koct in the table using the
following formula: L A10 = LW + Koct The correction Koct is the average value for the application area for the LYRA chilled
beam cassette.
Sound attenuation
The average sound attenuation ΔL of the LYRA chilled beam cassette from duct to room includes damping the
connecting duct's opening when the product is installed on the ceiling.
