The bimetal radiator Extreme is an injection-moulded radiator made up of individual elements – sections connected to each other by means of nipples. Tightness at the joints of the sections is ensured by sealing gaskets. The vertical steel tube inlay, increased thickness of sleeves and high quality of special aluminium alloy guarantee exceptional performance. The radiator is painted using the anaphoresis process, with a final phase of epoxy-polyester spraying. As a result, the radiator gets a perfect RAL 9016 white colour coating. The paint is applied to the entire surface of the radiators, both on the front and rear sides and on the ends – between the fins.
