2.1.1. Contact cooling ceiling system KKS-3/LD, 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 adhesive.


Nominal length 500 mm - 3 000
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 75 W/m² at Δt = 8 K for KKS-3 elements glued 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 metal ceiling can be used for cooling and the ceiling keeps all other desired properties, e.g. good sound absorption
  • Low suspension height – cooling ceiling elements assembled no higher than the ceiling panel
  • The core of the system is a copper serpentine pipework with aluminum heat conducting profiles, thus long service life and assured quality; operating pressure 6 bars (higher values on enquiry)
  • Reduction of “grey energy” and thus well suited for Leeds, DGNB, etc. buildings
  • Easy and safe Installation
  • No combustible components
