Key Features
- Genuine OEM Construction — Factory-original tank material and geometry ensure correct fluid capacity and secure mounting to the roller frame without modification.
- Broad RD-Series Coverage — Fits RD24-100, RD27-120, RD28-120, RD40-130, and RD45-140 tandem rollers across standard, open-ROPS, canopy, DPF, and US-market configurations.
- Direct Drop-In Replacement — OEM-matched fittings and mounting points align with existing lines and hardware, allowing straightforward installation on the drum wetting circuit.
- Protects Drum Wetting Performance — A properly sealed, intact additive tank maintains consistent water and additive delivery to the drums, preventing asphalt pickup and surface defects during compaction passes.
- Sourced from Wacker Neuson — Part number 5100012144 is a current, cataloged OEM part, so you receive the same component supplied through authorized Wacker Neuson dealer channels.
The additive tank stores the water-and-additive mixture that is continuously fed to the steel drums on a ride-on tandem roller during asphalt compaction. Keeping the drum surfaces wetted with this solution prevents hot asphalt from sticking to the drums, which would otherwise cause tearing of the mat and uneven surface finish. When the additive tank cracks, leaks, or loses its fittings, the drum wetting system can run dry or deliver inconsistent flow, leading to material pickup, roller marks, and rework on the finished surface.
