GLOBAL SATISFACTION FOR 

.… the end user: optimal air diffusion and the guarantee of global comfort. 

.… the architect: discreet integration inside the suspended ceiling. 

.… the designer: the proposition of an innovative solution 

.… the building occupier: an orientated air jet diffusion. 

.… the installer: a complete integrated “All-in-One” air diffusion system. 

.… the operator, thanks to real savings: low energy consumption, easy maintenance, ... 

USE 

COADIS 2 is a non-independent terminal air conditioning unit 

installed in suspended ceilings which combines low cost 

installation and operating advantages of central hot/chilled 

water production with individual temperature control for each 

room. Hydraulic connections can be installed in the suspended 

ceiling of the corridor adjacent to the room, and condensates 

can be drained by gravity (water pump not required). 

OPERATING PRINCIPLE 

The centrifugal fan uses a high-efficiency impeller to draw in air 

through a perforated return air register. The air is filtered then 

warmed or cooled as it passes through a high-efficiency heat 

exchanger containing hot or chilled water and/or an electric 

heater. Air is then pulsed horizontally into the room by 

COANDA effect through several directional diffusion nozzles 

with a high induction rate. 

RANGE 

COADIS 2 is particuarly adapted to office configurations up to 

3 panels wide (3 x 1.35 m) and 6 m long max. 

The 3 sizes of the COADIS 2 cover a range of air flows from 

130 to 800 m3/h, meeting the most stringent sound level 

requirements. 

Type 235/11 fits into 600 × 600 mm panels 



Two models, Classic and Raised, are available, and in most 

cases there is no need for a draining pump (and therefore 

maintenance is reduced). 

The white RAL 9010 panel integrates perfectly into suspended 

ceilings. 

Consult us for special panel sizes: 650 × 650, 650 × 1300, 

675 × 675, 675 × 1350, etc. 

CIAT takes part in the EUROVENT fan coil unit certification programme, see performances in Eurovent mode, on last page of the range. 

The list of products and certified characteristics is given in the EUROVENT directory and on the web site www.eurovent-certification.com .

COADIS 2 are non-independent terminal air conditioning units 

installed at the end of a room. Their dimensions are suitable for 

integration into standard 600 × 600 suspended ceiling panels. 

The units are easy to install on four threaded rods, preferably 

with resilient mounts. The unit is designed so as to avoid the 

installation of a draining pump in most cases. The hydraulic 

connections can be made from pipes in the suspended ceiling 

of the corridor adjacent to the room, and condensates can be 

drained by gravity directly into the main evacuation pipe. 

Figure A 

COADIS 2 solves indoor air quality problems by a comfort-type 

approach, optimising air diffusion and minimising power 

consumption. The entire air diffusion system is included in the 

intake/outlet panel, with no additional ducts or grilles. 

To optimise air diffusion, we use nozzles with a high induction 

coefficient, causing the ambient air to be drawn along by the 

discharge air. This enables the air stream to stick to the ceiling 

by Coanda effect, avoiding draughts in the occupied area of the 

room. The units are designed for offices up to 5 or 6 metres 

long. 

The directional nozzles enable the range of the air jet and the 

lateral component to be adjusted (see Figure A). 

Similarly, the air jet can be directed at a chosen angle, allowing 

the COADIS 2 to be installed in a corner and still maintain good 

air distribution.

The COADIS 2 is designed in accordance with the 

requirements of the ISO 7730 standard: “Determination of the 

PMV and PPD indexes and specification of the conditions for 

thermal comfort conditions”. 

In short, the COADIS 2 is designed for optimal reduction of 

local discomfort factors in the occupied volume, as shown on 

the graphs above: 

● Recommended vertical temperature gradient with max. 

difference of 3°C. 

● Asymmetric radiation minimised by effective air mixing (cold 

wall phenomenon). 

● Recommended floor temperature between 23 and 25°C for a 

seated person. 

● No draught felt by the user, with air speeds not exceeding 

0.25 m/s in normal operating conditions. 

Acoustic comfort has not been overlooked, as shown by the 

comfort levels on next pages. 

We have defined the occupied zone in accordance with the 

CEN TC 156 WG6 European working group “Design criteria for 

the indoor environment”, that is: 

■ Distance from external window: 1.0 m 

■ Distance from external wall: 0.5 m 

■ Distance from entrance door: 1.0 m 

■ Distance from internal wall: 0.5 m 

■ Distance from floor: 1.8 m 

Obstacles in the air stream (beams, light fittings, etc.) should 

be avoided as the air jet can behave in one of three ways: 

■ Breaks away from the ceiling and drops, disturbing comfort. 

■ Breaks away from the ceiling then rises again downstream 

from the obstacle. 

■ Ignores the obstacle. 

It is clear that various construction trades must work together 

to ensure thermal and acoustic comfort and high quality air 

diffusion for users. On site tests should be carried out in order 

to optimise air diffusion and other parameters to obtain the 

desired comfort level.

Code 

● 

Condensate drain pump mounted on the 

unit with overflow safety device. 

- 7l/h maximum flow for 1m draining 

height and 5m maximal length of piping. 

- 6l/h maximum flow for 1m draining 

height and 10m maximal length of piping. 

Draining: 6mm internal diameter flexible 

tube, 8mm diameter nozzle. 

For higher drain heights, consult us. 

One regulation for each valve must be 

added to allow slaving the overflow 

safety device to the valve closing 

(condensates stopped)***. 

Approximate calculation of the 

condensed water flow : 

P total - P sensible (W) 

Qv (l/h) = 

680 

(View without valve as an indication).
