The Wacker Neuson Case is a genuine OEM enclosure component designed for the HI-series indirect-fired air heaters and HDR-series direct-fired radiant heaters. This is a direct-fit replacement for a wide range of Wacker Neuson heating equipment, including the HI 110D, HI 200D, HI 300D, HI 400HD D, HI 90, HI 120, and HDR 115 and HDR 155 models. As a genuine OEM part sourced directly from Wacker Neuson, the is manufactured to the same specifications as the original component installed at the factory. Verify your model number before ordering to confirm fitment across this extensive HI and HDR heater lineup.
Key Features
- Genuine OEM Enclosure Integrity — Manufactured by Wacker Neuson to match the original case geometry, mounting points, and material grade — ensuring proper alignment and seal of all internal heater components.
- Direct-Fit Replacement — Designed to mount in the same position as the original, with no reworking of adjacent components or hardware required for installation.
- Broad HI and HDR Series Compatibility — Fits a wide range of Wacker Neuson indirect and direct-fired heaters, including the HI 90, HI 110D, HI 120, HI 200D, HI 300D, HI 400HD D, HDR 115, and HDR 155 series.
- Protects Critical Heating Components — The case houses and shields the burner assembly, heat exchanger, and combustion components from physical damage, moisture ingress, and jobsite debris that can compromise heater output and longevity.
- Combustion Safety Compliance — A correctly fitted, undamaged case is essential for maintaining proper airflow separation between combustion exhaust and conditioned output air — a critical safety function on indirect-fired heater designs.
The case on a Wacker Neuson HI or HDR series heater serves as the primary structural enclosure that houses and protects the internal combustion and heat transfer components. On indirect-fired models, it also plays a key role in maintaining the physical separation between exhaust gases and the heated air stream delivered to the work area — meaning a cracked, warped, or damaged case is not just a cosmetic issue but a functional and safety concern. When the case is compromised, the machine may lose heat output efficiency, develop air leaks, or fail to pass combustion safety checks. Replacing a worn or damaged case with the genuine OEM 5000183986 restores the heater's structural integrity and keeps it operating as intended through cold-weather construction, concrete curing, or temporary heat applications.
