The Wacker Neuson Cover is a genuine OEM component designed for the HI 300HD D, HI 300D, HI 90, and HI 90HD indirect-fired air heaters. As a direct factory replacement, this cover installs exactly as the original, maintaining the structural and thermal integrity of the heater enclosure. It is sourced directly from Wacker Neuson, ensuring full compatibility across all listed HI-series heater models.
Key Features
- OEM-Matched Enclosure Protection — Manufactured to the same material and dimensional specifications as the original, ensuring the heater housing stays sealed against job-site elements.
- Direct-Fit Replacement — Mounts directly to the HI 300HD D, HI 300D, HI 90, and HI 90HD heater frames with no modification to mounting points or fastener locations.
- Multi-Model Compatibility — A single part number covers four HI-series indirect-fired diesel air heater configurations, simplifying reordering across your fleet.
- Enclosure Integrity Maintained — A properly fitted cover keeps internal combustion and heat-exchange components shielded from debris, moisture, and physical damage that can degrade heater output.
- Genuine Wacker Neuson Part — Supplied as genuine OEM, verified against Wacker Neuson parts documentation for the HI indirect-fired heater range.
The cover on an indirect-fired air heater serves as the outer protective enclosure for the unit's internal components, including the burner assembly and heat exchanger. It shields these components from physical impact, moisture, and airborne debris during operation and transport, which is especially important in harsh outdoor or construction site environments. When a cover becomes cracked, warped, or missing, internal components are exposed to damage that can compromise heating output, shorten service life, or create unsafe operating conditions.
