Introduction
Chilled Water Cassettes offer cost-effective air conditioning solutions that integrate seamlessly into standard false ceiling modules. They are compatible with water chillers for both cooling and heating applications, although simultaneous operation of hot water and electric heating is prohibited.

Design Features
The units are compact, insulated, and designed for easy installation. Key features include three-speed ventilation, built-in electric heating, a condensate pump, and a combined discharge/air return grille with an air filter.

Casing and Insulation
The casing includes panels and an insulated sheet with adjustable air distribution. The unit is designed for heat and sound insulation.

Ventilation and Filtration
The unit uses a centrifugal turbine with a direct drive motor, equipped with thermal safety devices. The air filter is cleanable and made from woven synthetics, offering 55% efficiency.

Electric Heating
Factory-equipped with electric heating, the system includes thermostats for temperature protection. Kits for control, such as a condensing tray and motorized 3-way valve, are available.

Technical Data
Models 30 and 45 are available in 2-pipe and 4-pipe configurations. Key specifications include nominal cooling and heating capacities, airflow rates, and pressure loss values. The units operate at a nominal supply voltage of 230V/50Hz.

Electrical Data
Details on power supply, nominal and maximum current, and fuse ratings are provided for both ventilation and electric heating operations.

Condensate Pump
The pump operates at 230V/50Hz with a power input of 16W and a maximum water flow of 240 l/h.

Cooling and Heating Capacities
Cooling capacities are detailed for various airflows and water temperatures. Heating capacities are provided for different airflows and water temperatures.

Pressure Drops
Pressure drop data is provided for different glycol concentrations and water flows.

Field of Operation
Specifications for using chilled and hot water are outlined, including maximum and minimum temperature limits.

Fresh Air Intake
Fresh air flow should not exceed 12% of nominal air flow. An anti-frost thermostat is required for winter applications.

Dimensions
Dimensions and descriptions for 2-pipe and 4-pipe units are provided, including details on water couplings and ports for air distribution.

3-Way Valve with By-pass
The kit includes a motorized 3-way valve with by-pass for controlling the cassette in chilled or hot water mode.

Electrical Wiring Diagrams
Standard wiring diagrams for 2-pipe and 4-pipe cassettes are included, with a note that diagrams may change without notice.

Note
Products are subject to change as part of ongoing improvements. Contact information for the CAC Export Department is provided.
