The Wacker Neuson Regulator 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, and HI90HD. Sourced directly from Wacker Neuson, this regulator matches the original part specification for a correct, confident installation. It is a direct replacement for the factory-installed unit across the full range of compatible HI-series heaters listed above.
Key Features
- Genuine OEM Pressure Regulation: — Manufactured to Wacker Neuson's original output specification, ensuring the regulator delivers consistent fuel pressure control for stable heater combustion.
- Drop-In Replacement: — Engineered to the same mounting configuration and connection points as the original, allowing straightforward installation without additional hardware.
- Broad HI-Series Compatibility: — Fits HI35, HI90, HI90HD, HI110D, HI110HD D, HI200D, HI200HD D, HI300D, HI300HD D, and HD70 indirect-fired diesel air heaters.
- Stable Heat Output: — A correctly functioning regulator maintains steady fuel delivery to the burner, supporting consistent BTU output across operating conditions — especially critical in cold-weather construction and curing applications.
- Fuel System Safety: — The regulator is a primary pressure-control component in the heater's fuel circuit. A worn or failed unit can cause erratic flame behavior or uncontrolled fuel flow, making timely replacement essential for safe heater operation.
The regulator controls fuel pressure within the heater's burner system, ensuring the correct volume of diesel is delivered to the combustion chamber at a consistent, controlled pressure. Stable regulation is essential for clean ignition, steady heat output, and efficient fuel consumption — all of which are critical when using indirect-fired heaters for concrete curing, structure heating, or cold-weather job applications. When the regulator begins to fail, symptoms typically include uneven heat output, ignition problems, or fuel delivery faults that prevent the heater from reaching or holding its set temperature.
