DUBAL-45 Aluminium Radiator 6 Elements. Element-based radiator, manufactured from die-cast aluminium alloy. Reversible model. Special attention has been paid to the design, as this is the first time this double aesthetic formula is presented. One side features the classic look of an aluminium radiator with front openings for high thermal performance, and the other replicates the elegant line of the well-known DUBA radiator, which Baxi Heating has successfully introduced to the European heating market.
