Dynapac CP2100W Pneumatic Tired Roller

The Dynapac CP2100W is a large-class 21-ton pneumatic tired roller designed for high-performance asphalt compaction and sealing. With seven wide tires (three front, four rear) in an overlapping layout, it delivers smooth, uniform, and airtight compaction.
Its flexible ballast system allows easy weight adjustment using water, wet sand, or steel for balanced ground pressure. Equipped with hydrostatic drive, dual-circuit braking, and a swiveling operator station, it ensures excellent control and safety.
Powered by a Cummins 120 hp (Tier 4F) or 99 hp (Tier 3) diesel engine, the CP2100W offers high efficiency and reliability. Optional Air-on-the-Run, heat covers, and automatic water control (AWC) make it ideal for asphalt finishing, chip sealing, and light soil compaction.
