The Wacker Neuson Additive Tank is a genuine OEM component designed for the RD 24-100, RD 27-120, RD 28-120, RD 40-130, and RD 45-140 series double drum rollers. As a direct OEM replacement, this part is manufactured to the same standards as the original, ensuring a correct, drop-in fit with no guesswork. The covers an extensive range of RD series variants including standard, canopy, open-ROPS, and DPF-equipped models. When the additive tank cracks, leaks, or becomes damaged, replacing it promptly with the correct OEM part keeps your roller's fluid system operating as intended.
Key Features
- OEM-Matched Fluid Capacity — Manufactured to the original tank volume and port dimensions, ensuring correct additive delivery without under- or over-dosing.
- Direct Drop-In Replacement — Designed to mount using the original hardware and connection points on RD series rollers, fitting securely without modification.
- Broad RD Series Compatibility — Fits RD 24-100, RD 27-120, RD 28-120, RD 40-130, and RD 45-140 variants, including standard, canopy, open-ROPS, and DPF-equipped models.
- Sealed Integrity — Built to resist cracking and leakage under the vibration and thermal cycling typical of compaction equipment operation.
- Protects Drum and Surface Performance — A fully functional additive tank ensures consistent water or additive flow to the drums, preventing asphalt or material adhesion during compaction passes.
The additive tank on a double drum roller stores the fluid — typically water or a release agent — that is metered onto the drums during compaction work. This prevents hot asphalt or compacted material from sticking to the drum surface, which can cause uneven compaction and surface defects. If the tank is cracked, leaking, or otherwise compromised, drum wetting stops or becomes inconsistent, directly affecting the quality of the finished surface and potentially damaging the drums themselves.
