KORAFLEX FI 11/20

Floor convector with forced convection for heating or cooling

depth 11 cm, width 20 cm
  • used for heating or cooling
  • high heating and cooling output
  • two-pipe system
  • stainless steel design Inox AISI 304 for dry environment only
  • the narrowest type of compact dimensions
  • the convector use in for dry environment only
  • possibility to control through BMS (Building Management System)
  • the convector use in for dry environment only

* The average distance to connect all manufactured lengths of the KORAFLEX FI 11/20 convectors is 160 mm.
* For the standard version of the KORAFLEX FI 11/20 floor convector, the walkable cover grid in its longitudinal version cannot be used. It is always necessary to consult a particular installation and, if needed, to make technical adjustments to the convector case.
