Confirm compatibility using part number 05579321 and your machine's model code before ordering.
Key Features
- Genuine OEM Thermal Output — sourced directly from Bomag, this heating unit delivers the same rated heat output as the original, keeping the operator cab at the correct working temperature across cold-weather operations
- Exact-Match Replacement — engineered to the original mounting configuration and connection points, this unit installs into the cab assembly without modification to brackets, ducting, or wiring harnesses
- Wide Model Coverage — fits a broad range of Bomag tandem rollers including BW 154, BW 161, BW 170, BW 174, BW 190, BW 202, and BW 203 series models, pneumatic tyred rollers including BW 24 RH, BW 25 RH, BW 27 RH, and BW 27 RH-4i, as well as BC 462 and BC 472 compactors
- Operator Comfort and Productivity — a fully functioning heating unit maintains a safe, comfortable cab environment, supporting operator focus and sustained productivity during cold-climate paving and compaction work
- Windshield Defrost Capability — proper heat output supports effective windshield and window defrosting, maintaining clear sightlines critical for safe machine operation on active job sites
The heating unit supplies warmed air to the operator cab, drawing engine coolant heat through a core and distributing it via the cab's ventilation system. It keeps the interior at a safe, comfortable temperature during cold-weather operations and also provides the heat needed to defrost windows and maintain clear visibility. When the heating unit fails or degrades — through core leaks, blocked passages, or component wear — cab temperature drops, windows fog or ice over, and operator conditions deteriorate, directly affecting safety and the quality of compaction work being performed.
