The Wacker Neuson Box Control Weldment is a genuine OEM component designed for the HI750 and HI900 series mobile indirect fired air heaters, including diesel, natural gas, and dual-fuel configurations. Sourced directly from Wacker Neuson, this weldment matches the original assembly specification — ensuring it drops into place without fitment guesswork across the full range of compatible heater models. Coverage spans standard skid-mounted units, surge brake-equipped models, and cold-weather-rated variants down to -40°, making it one of the broadest-reaching structural control components in the HI series lineup.
Key Features
- Genuine OEM Structural Integrity — Manufactured to Wacker Neuson's original weld and dimensional tolerances, ensuring the control enclosure maintains correct alignment and load-bearing integrity within the heater frame.
- Direct-Fit Replacement — Matches the original bolt pattern and mounting interface of the HI750 and HI900 series heaters, so installation follows the same procedure as the factory assembly.
- Broad HI Series Compatibility — Fits a wide range of HI750 and HI900 configurations including diesel, natural gas, LP, dual-fuel (DGM), skid-mounted, surge brake, and -40° cold-weather models.
- Control System Protection — The weldment forms the structural housing that protects control components from vibration, impact, and exposure during operation — a compromised or cracked box puts the entire control assembly at risk.
- Verified OEM Part Number — Part number 5000180565 is the factory-designated replacement, eliminating compatibility uncertainty when ordering for mixed-fleet HI series heater operations.
The Box Control Weldment serves as the structural enclosure and mounting framework that houses the heater's control components. It anchors the control assembly securely within the heater unit, protecting internal components from mechanical stress, vibration, and environmental exposure during operation. When this weldment is cracked, deformed, or otherwise compromised, control components can shift out of alignment or become exposed to damage — leading to operational faults or heater shutdown in demanding jobsite conditions.
