Upper deflector 260x195x19 De Dietrich 7604534

The upper deflector, measuring 260x195x19, is a heat-resistant panel installed in the combustion chamber to direct the flow of hot gases and improve heat transfer. It helps optimize the efficiency of the boiler by ensuring that exhaust gases pass over heat exchange surfaces effectively. This component is often made from refractory material to withstand high temperatures and thermal cycling. When the deflector becomes cracked or eroded, it can reduce boiler efficiency and increase fuel consumption. Replacing it during routine boiler maintenance restores proper gas flow and enhances overall heating performance.
