REMKO DKT-4 SERIES Ceiling cassettes as 4-pipe system

Ceiling cassettes for heating and cooling

The warm room air is suctioned in a centred manner via an internal regenerative air filter. The four-sided special diffuser cover allows two, three or four sided air distribution below the ceiling. The three-stage low-noise radial fan allows the optimal adaptation of the airflow volume to prevailing conditions. The copper-aluminium heat exchangers are designed for medium temperatures of up to 80°C. The units are fitted as standard with a condensate pump. Optionally, fresh air can be blown in or adjoining rooms can also be cooled. A "cooling" valve assembly is supplied as standard for medium control. The control of the heating circuit can be adapted to the unit.

  • The ideal solution for optically discreet air-conditioning
  • Compact dimensions in standard European grid format
  • Low-noise unit operation
  • Service-friendly unit structure
  • Air outlet with adjustable fins
  • Installed condensate pump (up to 550 mmWS)
  • "Cooling" valve subassembly with connecting pipes 


Ceiling mounted cassettes for insertion into false ceilings are operated using a room temperature control or a precision room temperature control, either individually or in groups. The elegant and functional controls can be integrated into any wall decoration. The operating panel has a selector switch for the operating mode and the fan speed, a main switch, and a temperature controller for setting the desired room temperature.

Cooling load calculation for air-conditioners

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.
