The Wacker Neuson Knob is a genuine OEM component designed for the HDR 155 Direct Fired Radiant Heater and HDR 45 direct fired radiant heaters. As a factory-sourced part, it is manufactured to the exact specifications of the original, ensuring consistent operation and a proper fit within the heater's control assembly. This knob is the correct replacement choice for operators maintaining Wacker Neuson HDR-series heaters on demanding jobsites where reliable heat output is essential.
Key Features
- Genuine OEM Construction — Manufactured to Wacker Neuson's original material and dimensional specifications, so the knob delivers the same tactile control feel and engagement as the part it replaces.
- Direct Drop-In Replacement — Engineered to mount to the original control shaft or post without alteration, restoring full operability to the heater's control interface.
- Confirmed HDR-Series Fitment — Verified compatible with the HDR 155 Direct Fired Radiant Heater and HDR 45, covering both models in Wacker Neuson's direct fired radiant heater lineup.
- Restored Operator Control — A damaged or missing knob makes precise heat output adjustment difficult; this replacement puts accurate control back in the operator's hands.
- Fuel System Safety Relevance — On direct fired heaters, positive control over burner settings is critical; a secure, properly fitting knob helps operators make intentional, accurate adjustments to fuel-related controls.
The knob on a direct fired radiant heater serves as the primary interface between the operator and the heater's control mechanism — typically governing burner output, fuel flow, or ignition settings depending on its position on the unit. When a knob cracks, strips, or goes missing entirely, the operator loses the ability to make precise, confident adjustments, which can affect both comfort and safe heater operation. Replacing a worn or damaged knob with the correct OEM part restores full control function and keeps the heater operating as intended.
