The Wacker Neuson Combustion Chamber is a genuine OEM component designed for the HI110HD D, HI110D, and HI35 indirect-fired diesel air heaters. Sourced directly from Wacker Neuson, this part carries the same specifications as the original — ensuring the heater performs exactly as it was engineered to. It is a direct-fit replacement for the combustion chamber position in all three compatible HI-series heater models. If your unit is producing weak heat output, visible soot, or irregular flame patterns, a worn or damaged combustion chamber is a likely cause.
Key Features
- OEM-Grade Heat Resistance — Manufactured to withstand the sustained high-temperature combustion environment inside diesel indirect air heaters, maintaining structural integrity across heating cycles.
- Direct-Fit Replacement — Matches the original mounting dimensions and burner alignment of the HI110HD D, HI110D, and HI35, allowing straightforward installation without modification to surrounding components.
- HI-Series Heater Compatibility — Confirmed fitment across the HI110HD D, HI110D, and HI35 diesel indirect air heater models, covering both standard and heavy-duty variants in the lineup.
- Restored Combustion Efficiency — A correctly seated combustion chamber ensures complete fuel burn, consistent heat output, and proper flame containment — restoring the unit's rated heating capacity.
- Fuel System Safety Compliance — The combustion chamber is a critical containment component in any indirect-fired heater. Using a genuine OEM part ensures the flame envelope and exhaust path remain properly isolated from the heated airstream, as designed.
The combustion chamber is the core heat-generating enclosure inside a diesel indirect air heater. It contains and directs the burner flame so that heat is transferred to the outgoing airstream without introducing exhaust gases into it — which is what makes indirect-fired heaters safe for occupied or enclosed spaces. When the combustion chamber cracks, warps, or burns through, the heater may lose heat output, produce uneven temperatures, or allow combustion byproducts to contaminate the heated air. Replacing a failed chamber with a genuine OEM part like the Wacker Neuson 5000186800 restores the correct combustion geometry and keeps the unit operating safely and efficiently.
