The Wacker Neuson Nozzle is a genuine OEM component designed for the HI110HD D, HI110D, and HI35 indirect-fired diesel air heaters. As a factory-sourced part, it matches the exact spray pattern, flow rate, and thread specification required by the original burner assembly — no guesswork, no adaptation. Whether you're servicing a heater on a cold-weather concrete pour or restoring a rental unit to full output, this is the correct replacement nozzle for these Wacker Neuson HI series machines.
Key Features
- Exact Spray Geometry: — Genuine OEM construction ensures the atomization angle and flow rate match the original burner specification, so the heater fires cleanly and efficiently from the first ignition cycle.
- Direct Burner-Assembly Fit: — Engineered to thread directly into the burner head of HI series indirect heaters, using the same connection geometry as the factory-installed nozzle for a straightforward service swap.
- Confirmed Fitment: — Verified for the HI110HD D, HI110D, and HI35 indirect-fired diesel air heaters across the Wacker Neuson HI product family.
- Clean, Complete Combustion: — A correctly functioning nozzle delivers the right fuel mist to the combustion chamber, supporting full heat output and stable flame. A worn or clogged nozzle causes misfires, sooting, and reduced BTU output.
- Fuel System Safety: — The nozzle is a critical fuel-delivery component; using the correct OEM-spec part helps maintain safe combustion pressures and reduces the risk of fuel leakage or uncontrolled flame behavior.
The nozzle in a diesel indirect-fired air heater is responsible for atomizing fuel into a fine mist before it enters the combustion chamber. Proper atomization is essential — without it, the burner cannot achieve a stable, efficient flame, leading to incomplete combustion, sooting of the heat exchanger, and reduced heat output. Over time, nozzles wear, clog, or suffer deposit buildup that disrupts the spray pattern; replacing the nozzle at regular service intervals restores the heater to its rated performance and keeps the combustion process running safely.
