The Wacker Neuson Electrode is a genuine OEM ignition electrode designed for Wacker Neuson HI and HDR series indirect and direct-fired air heaters, including the HI 90, HI 120, HI 200D, HI 200HD D, HI 300D, HI 300HD D, HI 400HD D, HDR 45, HDR 155, and HD 70. As a direct OEM replacement, part is manufactured to the same specification as the original component, ensuring correct positioning, spark gap, and terminal connection within the burner assembly. This electrode fits a wide range of Wacker Neuson diesel and direct-fired heater models, making it a dependable choice for scheduled maintenance or field repair. Keep a spare on hand during cold-weather seasons when heater uptime is critical.
Key Features
- Correct Spark Gap and Tip Geometry — Manufactured to OEM ignition specifications so the electrode fires reliably in the burner chamber without adjustment.
- Genuine OEM Part — Sourced directly from Wacker Neuson; identical in material, insulator grade, and terminal design to the original electrode.
- Drop-In Burner Assembly Fit — Matches the original mounting bracket position and wiring connector for a straightforward swap with no reworking of the burner head.
- Broad HI and HDR Series Coverage — Fits HI 90, HI 120, HI 200D, HI 200HD D, HI 300D, HI 300HD D, HI 400HD D, HDR 45, HDR 155, and HD 70 heater models.
- Fuel System Safety Compliance — A correctly seated electrode ensures clean ignition of the diesel fuel charge; a worn or cracked electrode can cause misfires, unburned fuel buildup, or failed startups in cold conditions.
The ignition electrode in a diesel or direct-fired air heater generates the high-voltage spark that ignites the fuel-air mixture at the burner nozzle. When the electrode tip erodes, cracks, or its insulator becomes carbon-fouled, the spark either weakens or fails entirely, resulting in a no-heat condition, repeated lockouts, or incomplete combustion. Replacing a worn electrode with a correctly specified OEM part restores consistent ignition and keeps the heater cycling cleanly through its startup sequence — especially important when the unit is operating in low-temperature environments where reliable heat output is essential to protect workers and prevent concrete or equipment freeze damage on the jobsite.
