2.1.2 Contact cooling ceiling system KKS-5/LD-M, for metal ceilings

Designed for use with plane metal acoustic ceilings to make radiant cooling or heating ceilings. The permanent large-surface contact between the cooling elements and the ceiling panels is done with magnets.


Nominal length 500 – 3 000 mm
Nominal width ≤ 16 pipe rows x pipe spacing
Pipe spacing ≥ 90 mm (standard)
Nominal height ≤ 15 mm
Suspension height ≥ 100 mm
Connection type push-in fitting


  • Heat transfer mainly by radiation, resulting in very high thermal comfort
  • Standard cooling capacity up to 95 W/m² for KKS-5 elements laid onto metal acoustic ceiling panels made of sheet metal (to EN 14240)
  • High system flexibility thanks to various element designs and sizes available; thus any type of ceiling can be used for cooling and the ceiling keeps all other desired properties, e.g. good sound absorption
  • Low suspension height
  • The core of the system is copper serpentine pipework with Al heat conducting profiles, thus long service life and assured quality; operating pressure 6 bars (higer values on enquiry)
  • Easy and safe installation
  • No combustible components
