The small design height of the ceiling-mounted cassettes of 258 and 298 mm allows installation in almost every false ceiling. The distribution of air to all four sides ensures even air distribution. The copper-aluminium round heat exchangers are designed for medium temperatures of up to 70°C.
The 5-speed radial fan allows the optimal adaptation of the air flow rate to prevailing conditions. Ceiling-mounted cassettes are fitted as standard with an internal condensate pump. Optionally, fresh air can be blown in or adjoining rooms can also be cooled.

- 5 fan speeds
- Installed condensate pump (up to 1000 mmWS)
In KWD 25 to KWD 100 series units, the cooling, heating, ventilation or dehumidification modes of the ceiling cassettes can be controlled automatically or manually by the operator using an infrared remote control. It is also possible to set the desired temperature, time and switch-on or switch-off time easily with the press of a button. When using multiple ceiling cassettes within a room or building, a single infrared remote control within an internal network can be used to control all of the units. With a cabled remote control within an internal network, each individual ceiling cassette can be individually addressed and programmed. Medium output can be controlled using the optional three-way valve assembly or by a valve assembly fitted to the equipment.

The following rule of thumb applies when calculating the cooling capacity:
Approximately 30 W of cooling capacity are required per cubic meter. The cooling capacity for a room with a surface area of 28 m2 and height of 2.5 m can be calculated as follows:
28 m2 x 2,5 m x 30 W/m3 = 2.100 Watt (2,1 kW)
We recommend that you always calculate the cooling capacity for the room precisely.
