The Wacker Neuson Turbulator is a genuine OEM component designed for the HI series indirect-fired diesel air heaters, including the HI110D, HI110HD D, HI200D, HI200HD D, HI300D, HI300HD D, HI35, HI90, HI90HD, and HD70 models. Sourced directly from Wacker Neuson, this turbulator meets the exact engineering specifications of the original part, ensuring correct fit and function within your heater's heat exchanger assembly. Whether you're servicing a light-duty HI35 or a heavy-duty HI300HD D, part number is the correct OEM replacement to restore peak heating performance. Keep your crew warm and your project on schedule with a part built to the same standard as the one that came out.
Key Features
- Optimized Heat Transfer Surface: — Engineered to create controlled turbulence in the exhaust gas flow, maximizing thermal energy transfer to the outgoing air stream for efficient, consistent heat output.
- Genuine OEM Construction: — Manufactured to Wacker Neuson's original material and dimensional specifications, so combustion gases and heat loads are handled exactly as the heater was designed to manage them.
- Direct Drop-In Replacement: — Matches the original mounting geometry within the heat exchanger tube, allowing straightforward installation without modification to surrounding components.
- Broad HI Series Compatibility: — Fits the HI35, HI90, HI90HD, HI110D, HI110HD D, HI200D, HI200HD D, HI300D, HI300HD D, and HD70 indirect diesel air heaters — covering a wide range of Wacker Neuson heating equipment in a single part number.
- Combustion Safety Relevance: — A degraded or missing turbulator can cause uneven exhaust temperatures, incomplete heat exchange, and potential overheating of the heat exchanger tube — making timely replacement an important part of safe heater operation.
A turbulator is an insert placed inside the heat exchanger tube of an indirect-fired air heater. Its purpose is to disrupt the laminar flow of hot exhaust gases passing through the tube, creating turbulence that forces the exhaust to make more contact with the tube wall — this is what transfers heat from the combustion side to the clean, breathable air being pushed out into the workspace. Without a functioning turbulator, exhaust gases can pass through too quickly and with too little wall contact, significantly reducing the heater's output efficiency. Over time, turbulators can corrode, warp, or burn through due to the high-temperature environment, and a failed unit will noticeably reduce the heater's ability to maintain target air temperatures even when fuel consumption remains unchanged.
