ACV 507F2005 turbulator DELTA c 45/55-25 bf

A turbulator is a component installed inside the flue ways of a heat exchanger. Its function is to disrupt the flow of flue gases, slowing them down so that more heat is transferred to the water before the gases exit. Turbulators are typically used in boilers that have a secondary plate heat exchanger for domestic hot water production. When selecting a turbulator of this type, the key considerations are the dimensions and connection pattern specific to the boiler model, the number of flue ways it must fit, the material—commonly stainless steel, copper, or aluminium alloy—and the type of gasket used to seal it in place. Common failure modes for turbulators include scaling on the water side, soot accumulation on the gas side, gasket degradation, and, in condensing appliances, corrosion where condensate collects. This article is the ACV 507F2005 turbulator, designated for the DELTA c 45/55-25 bf. It bears the manufacturer code 507F2005 and the catalogue article number 129.841.005. As with any replacement turbulator, ensure that the physical dimensions and gasket type match the existing installation before fitting.
