Nominal width unperforated: 420 mm
perforated: 250 mm
Overall system height ≥ 80 mm
Connection type press fitting


  • Heat transfer largely by radiation, with very high thermal comfort as a result
  • Standard cooling output up to 69 W/m² at Δt = 8 K for KKS-4 elements combined with thermal gypsum board panels (to DIN EN 14240), heating capacity 102 W/m² (at Δt 12 K)
  • Also suitable for heating
  • Sound-absorbing types available
  • The core of the system is a copper serpentine pipework with an aluminum heat conducting plate, thus long lifetime and assured quality; operating pressure 6 bars (higher values subject to enquiry)
  • Easy and safe installation according to professional methods in use in building services and drywall construction
  • No combustible components
