Towel rail radiators KORALUX RONDO CLASSIC – M are produced from closed steel profiles with a D-shaped cross section and curved profiles with a circular cross section. They have a bottom middle connection with connecting pitch 50 mm. They are delivered with a set for wall mounting, including an air vent and blanking plugs.
They can also be used for combined heating.
For connection of the radiator to the heating system we recommend using the Connection fittings HM.
Their design enables drying textiles. This is why KORADO now offers also towel hangers and pegs which extend the practical use of KORALUX towel rail radiators.
