More information on cooling


Kampmann cold water cassettes KaCool D configured for KaControl control are supplied completely wired and ready for connection with all electrical components fitted. A powerful parameterisable microprocessor provides all of the functions, thus every cold water cassette KaCool D has its own "intelligence" and can be operated in groups by means of Kampmann-tLan or CANbus networks.


KaControl cold water cassettes KaCool D can be fitted with plug-in communications interfaces for single room operation or can also be connected to superordinate BMS systems. Every basic unit therefore has the potential to be integrated within a technical building management system.


  • Valve actuation for 2-pipe and 4-pipe systems
  • 5-stage fan control with automatic function based on room temperature
  • Temperature detection by KaController
  • Valve activation 24V OPEN/CLOSE
  • Evaluation of condensation alarm
  • Changeover function in 2-pipe systems (heating/cooling) via an external potential-free contact or a clip-on temperature sensor
  • Integration into open BMS systems by optional interface cards (BACnet, Modbus)

System set-up

Control zones with up to 6 cold water cassettes can be connected to a KaController via simple 2-wire bus connection.


Control zones with up to 30 cold water cassettes can be connected to a KaController via a CANbus connection.

When are cold water cassettes used for cooling?

Cold water cassettes KaCool D are used for air conditioning with recirculating air. They are designed for installation within a suspended ceiling and, when installed, all that is visible is their attractive front panel. Cold water cassettes KaCool D are simple to control and operate with water as their environmentally-friendly cooling medium.

In which sizes are the KaCool D chiller cassettes available?

The KaCool D chiller cassettes are available in two different sizes:


  • Sizes 1 to 3 with ceiling panel dimensions of 670 x 670 mm; the suspended ceiling height needs to be 296 mm.
  • Sizes 4 to 6 with ceiling panel dimensions of 965 x 965 mm; the suspended ceiling height needs to be 329 mm.
How are the units maintained?

The filter element fitted to protect the heat exchanger can be simply removed by opening the panel from below. It can be cleaned by rinsing with water or vacuuming. To prevent it from being damaged, the condensation tray should be regularly cleaned by a technician and the condensation pump should be checked.
