GENERAL DESCRIPTION
CWC
Model
Chilled Water Cassette
The CEILING CASSETTES are designed to operate with chilled and hot water. They provide both cooling and
dehumidification in cooling mode and heating in the latter, cleaning and filtering the air in the process. Electrical
heating elements are available as an option on some units. The units are available with cooling capacities from
1950 to 8450 W and heating capacities from 1400 to 10600 W.
CABINET
The unit chassis is made of galvanised steel and is fully insulated inside.
The units have been designed in order to install them in high ceilings where standard plates 600x600 mm or
600x1200 mm will be used.
DIFFUSER PANEL
Two alternatives can be chosen:
- Plastic diffuser: Made in decorative plastic, with a smooth finish. Internal insulation prevents condensation from
forming. 4 louvres for MODELS 600x600 and 6 louvres for MODELS 600x1200 ensure air distribution.
- Metallic diffuser.

HEAT EXCHANGER
Made of copper tubes and aluminium fins. Coils have been designed and manufactured to ensure maximum
efficiency.
FAN
The units are supplied with one (models 600x600) or two (models 600x1200) 3-speed centrifugal fans. The impeller
blades have been designed specifically for this type of units ensuring exceptionally low sound levels and the motor
is protected with internal thermal protection.
AIR DISTRIBUTION
The position of the louvres can be adjusted manually (only for plastic diffuser).
AIR FILTER
A polypropylene washable air filter is incorporated in the unit; it is easily accessible for maintenance.
INTERNAL COMPONENTS
The unit is designed with serviceability in mind, and all components are easily accessible. A drip tray collects
condensate which is removed by means of a condensate pump.
ELECTRIC CIRCUIT
The electrical panel is provided with a terminal block which provides connection to mains power or to a control box
(depending on model).
A fused isolator is not included and where required shall be installed by others.
