De Dietrich 83755503, sezione sinistra del modello DTG

This article is listed under heat exchangers with the designation De Dietrich 83755503 DTG left section (catalogue number 336.709.002). Parts of this type transfer heat from the flue gases to the water in a boiler. In condensing appliances a secondary plate exchanger is often used for domestic hot water. Turbulators are placed in the flue ways to slow the gases down, improving heat uptake. Selection is based on model-specific dimensions and connections, the number of ways or plates, material (stainless steel, copper, aluminium alloy), and gasket type. Typical failures include scaling on the water side, soot accumulation on the gas side, gasket leaks, and in condensing units corrosion where condensate collects. In the boiler system the heat exchanger receives heat from the burner and passes it to the circulation water. It works together with the pump, expansion vessel, and safety valve. When replacing a part of this type, verify the physical dimensions, connection layout, and orientation – the “left section” designation indicates a specific handed version. Gasket condition and material compatibility must also be checked. No further technical details for this specific article are available from the catalogue data.
