The Wacker Neuson Enclosure is a genuine OEM component designed for the HI750 and HI900 series indirect-fired air heaters. This is a factory-sourced part built to the exact specifications of the original, covering diesel, natural gas, propane, and DGM configurations across both skid-mounted and mobile unit variants. As a genuine Wacker Neuson part, the ensures a direct, correct-fit replacement that restores the structural and thermal integrity of the heater housing. Confirmed fitment spans a wide range of HI750 and HI900 models, including surge brake and heavy-duty surge variants.
Key Features
- Genuine OEM Construction — Manufactured to Wacker Neuson's original design tolerances, ensuring the enclosure panels seat, seal, and fasten exactly as the factory unit did.
- Broad HI-Series Compatibility — Fits multiple HI750 and HI900 configurations including diesel, natural gas, DGM, skid-mounted, and mobile indirect-fired air heater variants.
- Structural Housing Integrity — Restores the protective outer enclosure that shields internal burner, heat exchanger, and airflow components from jobsite exposure and mechanical damage.
- Weather and Heat Resistance — Built to withstand the operating environment of a high-output indirect air heater, including temperature cycling, moisture, and outdoor exposure down to extreme cold ratings on surge-equipped models.
- Direct Drop-In Replacement — Matches original mounting points, fastener patterns, and panel geometry on applicable HI750 and HI900 units, eliminating guesswork during installation.
The enclosure on a Wacker Neuson indirect-fired air heater serves as the outer protective housing that surrounds and safeguards the internal components — including the burner assembly, heat exchanger, and air-handling system. It maintains the structural form of the unit, protects critical internal parts from physical damage, weather intrusion, and contamination, and supports proper airflow routing through the heater. A cracked, damaged, or missing enclosure can compromise thermal efficiency, expose internal components to the elements, and create safety concerns around hot surfaces — making timely replacement essential to keeping the heater operating as intended.
