The Wacker Neuson Nozzle is a genuine OEM component designed for the HI 200 D and HI 200HD D indirect-fired air heater series. As a direct factory replacement, this nozzle installs to the original specification and restores proper fuel atomization for consistent, efficient combustion. Wacker Neuson genuine OEM parts are manufactured to the same standards as the original equipment, ensuring a correct fit across compatible HI 200 D and HI 200HD D models. Whether you're servicing a unit mid-season or completing scheduled maintenance, part number is the reliable choice to keep your heater performing at full output.
Key Features
- Genuine OEM Fuel Atomization Accuracy — Manufactured to the exact orifice and spray-angle specification of the original nozzle, ensuring the correct fuel-to-air ratio for clean, efficient combustion.
- Direct Drop-In Replacement — Matches the original thread size and seating geometry of the HI 200 D and HI 200HD D burner assemblies for a straightforward swap during service.
- Confirmed Fitment for HI 200 D and HI 200HD D Series — Verified for use across HI 200 D and HI 200HD D indirect-fired air heaters, including both standard and heavy-duty diesel configurations.
- Consistent Heat Output — A correctly functioning nozzle delivers a uniform fuel mist that supports stable flame ignition and steady BTU output; a worn or clogged nozzle can cause misfires, sooty exhaust, and reduced heating capacity.
- Fuel System Integrity — Using the correct OEM-spec nozzle helps maintain proper combustion chamber pressures and reduces the risk of unburned fuel buildup, which is a genuine safety consideration in any indirect-fired heating application.
The nozzle is the critical metering point in an indirect-fired air heater's burner system. It atomizes diesel fuel into a fine mist before it enters the combustion chamber, where it mixes with air and ignites to generate heat. The quality and geometry of the nozzle directly controls flame shape, combustion efficiency, and heat output — a nozzle that is worn, partially blocked, or incorrectly sized will cause hard starts, incomplete combustion, excess soot, or a heater that cycles off on safety lockout. Replacing the nozzle at the recommended service interval is one of the most straightforward ways to maintain peak performance from an indirect-fired heater.
