KORAFLEX FK

Floor convectors with natural convection

KORAFLEX FK and KORAFLEX FK InPool convectors are intended for embedding in floors, especially in places prohibiting installation of higher radiators, e.g. in front of french windows, winter garden entries, hall entrances, exits etc., in public buildings (shops, administrative buildings etc.), as well as in residential houses. Various coloured designs of the floor grids are making convectors suitable for each interior.
