ACV 50423367 turbulators ca 250 l.1250mm (24 pc)

The part listed is ACV 50423367, described in the catalogue as turbulators ca 250 l.1250mm, supplied as a set of 24 pieces. The approximate dimensions given in the product name indicate a length of 1250 mm and a cross‑section dimension of 250 mm (likely the width or diameter of the flue way). This is a service set intended to replace turbulators in a boiler’s heat exchanger. Turbulators of this type are inserted into the flue gas passages of the heat exchanger. Their function is to disrupt the smooth flow of exhaust gases, creating turbulence that slows the gases and improves the heat transfer from the flue gases to the water. By increasing the contact time and surface area exposure, they raise the efficiency of the heat exchanger, which is particularly important in condensing appliances where maximum heat extraction is desired. Selection of replacement turbulators is driven by the specific heat exchanger design: the shape, pitch, and number of flue ways, the material (often stainless steel or aluminium alloy), and whether the turbulators are sealed with gaskets. When fitting a new set, check the flue passages for soot accumulation or scale on the water side, and look for signs of corrosion in condensing boilers where condensate can collect. Damaged or missing turbulators reduce boiler efficiency and can lead to higher flue gas temperatures.
