The Wacker Neuson Nozzle 0.85 X 80 is a genuine OEM component designed for the HDR 155 Direct Fired Radiant Heater and HDR 45 direct fired radiant heater series. As a factory-sourced part, the meets the exact spray angle and flow rate specifications required for proper combustion performance in these units. It is a direct replacement for worn or clogged nozzles on compatible HDR models, restoring consistent heat output and efficient fuel atomization. Confirm your model number before ordering to ensure a correct fit.
Key Features
- Correct Spray Geometry: — Manufactured to the exact 0.85 flow rate and 80-degree spray angle spec, ensuring proper fuel atomization and combustion efficiency in HDR-series heaters.
- Genuine OEM Part: — Sourced directly from Wacker Neuson, this nozzle matches the original installed component without the need for adaptation or shimming.
- Verified HDR Fitment: — Confirmed compatible with the HDR 155 Direct Fired Radiant Heater and the HDR 45, covering both models within the Wacker Neuson direct fired radiant heater line.
- Restores Full Heat Output: — A worn or partially blocked nozzle causes uneven flame patterns, sooting, and reduced BTU output; replacing it with 5200011793 brings combustion back to proper operating condition.
- Fuel System Safety: — Using the correct OEM-spec nozzle in a direct fired heater is critical — an incorrect spray angle or flow rate can cause incomplete combustion, carbon buildup, or unsafe flame behavior.
The fuel nozzle in a direct fired radiant heater is responsible for atomizing diesel or kerosene fuel into a fine mist that mixes with air and ignites to produce radiant heat. The nozzle's spray angle and orifice size directly govern flame shape, combustion completeness, and heating efficiency — even minor deviations from spec can result in poor ignition, excessive soot, or fuel waste. When a nozzle wears, clogs, or degrades, the heater may fail to light reliably, produce uneven heat, or run inefficiently, making timely replacement essential for consistent performance on the jobsite.
