Ölvorwärmer mit Stab o-41 – De Dietrich JJX000535922

The oil preheater with rod o-41- is designed to warm the fuel oil before combustion, improving ignition and reducing emissions. This component is essential for burners that operate with heavy oil, as it lowers viscosity for better atomization. Replacing a faulty preheater can restore cold-start performance and overall burner efficiency.
