The Wacker Neuson is a genuine OEM Solenoid Coil designed for the HDR 45, HD 50, HD 70, HI35, HI 90, HI 90HD, HI 120, and HI 120HD indirect-fired air heaters. Sourced directly from Wacker Neuson, this coil meets the exact electrical specifications required by these heater models, ensuring correct actuation of the fuel valve every time. Confirmed fitment across the HDR and HI series makes part number a straightforward service replacement for technicians and fleet operators keeping their heating equipment running through demanding cold-weather jobs.
Key Features
- Correct Coil Resistance and Output: — Genuine OEM specification ensures the coil delivers the precise electromagnetic force needed to open and close the fuel valve reliably under load.
- Drop-In Electrical Connection: — Engineered to match the original connector and mounting configuration, so installation follows the same procedure as the factory part.
- Broad HI and HDR Series Coverage: — A single part number covers the HDR 45, HD 50, HD 70, HI35, HI 90, HI 90HD, HI 120, and HI 120HD indirect-fired heaters.
- Consistent Fuel Valve Control: — A correctly functioning solenoid coil maintains accurate fuel delivery timing; a failing coil can cause hard starting, erratic flame behavior, or complete heater shutdown.
- Fuel System Safety Compliance: — As a direct fuel-valve actuator, using the correct OEM coil ensures the heater's fuel shutoff responds as designed, supporting safe operation in enclosed or temporary-heat applications.
The solenoid coil is the electromagnetic component that controls the fuel solenoid valve on indirect-fired air heaters. When energized, the coil generates a magnetic field that opens the valve to allow fuel flow to the burner; when de-energized, it allows the valve to close and cut off fuel. If the coil degrades or fails, the heater may refuse to ignite, cycle erratically, or lose the ability to shut down cleanly — all of which affect both heating performance and safe operation on the jobsite.
