The Wacker Neuson Nozzle is a genuine OEM component designed for the HI 120 indirect-fired air heater. As a factory-sourced part, it meets the exact specifications Wacker Neuson requires for proper fuel atomization and combustion performance in the HI 120. Sourcing the correct OEM nozzle ensures the heater operates at its intended output and efficiency without the guesswork of cross-referencing aftermarket substitutes.
Key Features
- Correct Fuel Atomization Spec — Manufactured to the precise orifice size and spray pattern required by the HI 120 burner assembly, ensuring complete and efficient combustion.
- Genuine OEM Part — Sourced directly from Wacker Neuson, this nozzle carries the same part number (5200025111) used in original production, so you know it's the right component before it ships.
- Direct-Fit for the HI 120 — Designed to install into the HI 120 indirect-fired air heater burner head without modification, restoring the unit to its original operating condition.
- Sustained Heat Output — A correctly functioning nozzle maintains consistent fuel delivery to the burner, keeping the HI 120 producing steady, reliable heat on cold-weather jobsites.
- Fuel System Integrity — Using the correct OEM nozzle reduces the risk of incomplete combustion, sooting, and fuel system fouling that can result from an incorrect spray pattern or flow rate.
The nozzle in an indirect-fired air heater is responsible for atomizing diesel fuel into a fine mist before it enters the combustion chamber. This fine spray allows for efficient ignition and clean, complete combustion, which is what delivers consistent heat output through the heat exchanger without introducing exhaust gases into the heated air stream. When a nozzle wears or becomes clogged, fuel atomization degrades — leading to hard starts, uneven heat output, sooting of the combustion chamber, and in some cases, heater lockout or shutdown. Replacing the nozzle with the correct OEM part restores proper spray geometry and flow, returning the HI 120 to full heating performance.
