ACV 50423059 turbolatori ca 100 l.750mm (16 pz)

Turbulators are components installed in the flue gas passages of a heat exchanger. Their function is to create turbulence in the flue gas flow, slowing it down and increasing the contact time with the heat transfer surfaces. This improves thermal efficiency by extracting more heat from the combustion products before they exit the flue. Turbulators of this type are typically used in boilers with a fire-tube or similar flue-way design, often in medium to large-capacity units. They sit directly inside each flue tube and are held in place by the tube geometry or a retaining bracket. Selection of replacement turbulators is based on the specific dimensions of the flue passages—length, diameter, and the number of tubes in the heat exchanger. The material is also a factor; common options include stainless steel, aluminium alloy, or copper, depending on the operating temperature and condensate exposure in condensing boilers. The set described here comprises 16 pieces, which corresponds to a heat exchanger with 16 flue ways. The part is branded ACV and carries the manufacturer codes 50423059 and 129.841.004. When replacing turbulators, check the condition of the flue tube inner surfaces and the gaskets if present. Scaling on the water side and soot accumulation on the gas side can reduce performance, so it is advisable to clean the heat exchanger during the replacement. In condensing appliances, inspect for corrosion where condensate may pool near the turbulator ends.
