Electrode Elco 217578

Elco electrode 217578 (art. 390.946.025) Original universal electrode for ignition and flame monitoring systems. Elco electrode 217578 is an original component designed for installation in gas and oil burners Elco. The element is equipped with a standard plug and a fixed retainer, ensuring precise positioning inside the burner and preventing displacement from vibration during intensive operation. If your equipment fails to start, does not spark, or extinguishes shortly after ignition, the cause is often a malfunction of this element. Technical specifications: Part numbers: 217578, 390.946.025; Manufacturer: Elco (Europe); Electrode type: Universal (ignition and ionization); Connection type: Plug Ø4 mm; Retainer: Fixed. Key advantages: Versatility: This electrode can perform two functions: fuel ignition (spark generation) and flame monitoring (ionization). This simplifies spare parts storage — one part number is suitable for replacement in different burner units. Reliable fixation: The presence of a fixed retainer ensures precise positioning of the electrode inside the burner, preventing displacement from vibration and accidental malfunctions of the control unit. High-quality insulation: The ceramic insulator withstands high temperatures and prevents high-voltage breakdown to the burner body, ensuring durability and safety. Standard connector: The 4 mm plug ensures full compatibility with standard Elco high-voltage ignition and ionization cables. Operating principle and signs of malfunction: Ignition mode: High voltage from the transformer is applied to the electrode, creating a spark that ignites the fuel mixture. Sign of malfunction: No spark, burner does not start. Ionization mode: The electrode transmits a weak current
