COADIS Cassette is an independant terminal air
conditionning unit installed in suspended ceiling
which combines the installation and operating
advantages of central hot/chilled water
production with individual temperature controls
in each room.
c The entire air diffusion system is included
in the intake/outlet panel, with no additional
ducts or grilles.
c To optimise air diffusion, we use nozzles
with a high induction coefficient, causing
the ambient air to be drawn along by the supply
air. This enables the air stream to stick to
the ceiling by the “COANDA effect”.
c This unit is designed for offices until 3 large
frames (3x1,35 for ex.) and 6 m long maxi.
c COADIS Cassette inside the false ceiling instead
of panel (standard 600x600, or 600x1200).
c Easy installation: only four threaded rods
with resilient mounts.
c Hydraulic connections and condensate
evacuation by gravity (without water pump)
become easier according to the pipes installation
in the false ceiling of the corridor which
is generally lower high than in the office room.

The perfect air diffusion
by “Coanda effect“
c By orienting the diffusion outlets
appropriately we can reduce the
longitudinal and increase the lateral
range, ensuring comfort in shorter
rooms.
c An aesthetic key to precisely fix
nozzles position.
c You can set the air stream in any
direction, which means you can
even install the COADIS in a corner
of the office ceiling and still have
optimal air diffusion.

CEILING
COANDA EFFECT
c The COADIS Centrifugal fan pump the air
flow through a punched aluminium air grille.
After filtration the air flow is cooled (or heated)
through a coil. The air flow follows the ceiling
with Coanda effect. The COADIS Cassette uses
high induction nozzles.
c Coanda effect enables the air stream to adhere
perfectly to the ceiling thus avoiding “cold
dumping”. This virtual “casing” avoids
uncomfortable sensation due to the cool
air flow in the room, then the asymetrical
radiance is minimised near windows.
c This air flow which adheres to the ceiling
by “Coanda effect”, discovered by the Romanian
aerodynamic engineer Henri Coanda (1886-1972),
has the beneficial effect of an air flow induction
phenomenon. Thus, the air mixture in the room
is more important, as the heated airstream
is quickly pumped and mixed with the cool
airstream, plus the ambient temperature
in the room is more homogeneous.
c High induction of
the ambiant air flow.
c No By pass phenomenon
between nozzles and air inlet grille.
WINDOWS
c The air flow follow the ceiling.
c Virtual “casing”.

comfort
COADIS Cassette has been
developped to obtain
the best reduction of all local
discomforts in the occupied
zone (comfort zone):
c air speeds must not
exceed 0,25 m/s,
c temperature vertical
ratio must not exceed 3K,
c asymetrical radiance must
be minimized with good air
mixing (cold wall phenomenon),
c the ground temperature
must be between 23°C and 25°C
for a seated person,
c acoustic comfort, with
low noise level.
Obstacle in the air stream
(beams, light fitting, etc.) should
be avoided as the air jet can
break away from the ceiling and
disturb comfort level. It is clear
that various construction trades
must work together to ensure
thermal and acoustic comfort
and high quality air diffusion.
