Atlas Copco Road Construction Equipment is currently introducing a new range of mid-size Dynapac soil compactors, the CA2500 - CA3500. These machines incorporate “Efficiency Eccentrics”, a patented system of optimized eccentric elements, and are equipped with Stage IV/T4 Final engines with ECO Mode. In combination these features offer a substantial savings in energy and fuel, while reducing the impact of machine operation on the environment.

The Dynapac CA2500 - CA3500 have all the advanced features of Atlas Copco's fifth generation of Dynapac CA single drum vibratory rollers, but with a key difference. The CA2500 - CA3500 models are equipped with “Efficiency Eccentrics”.

Same high performance, lower operating costs

Atlas Copco is the first to introduce the “Efficiency Eccentrics” system to the market. In the new soil compactors the system of eccentric elements has been optimized by moving the weight to the right side of the axle, so that less weight counteracts the movement at start-up.
The result is impressive. Almost 11 kW less power is required to initiate the vibratory action, reducing energy consumption at start-up by 50% and thus using less fuel. This lower power requirement has also made it possible to reduce engine sizes yet still offer the same compaction performance as machines equipped with more powerful engines.
The engines in the CA2500 and CA3500 have outputs of 89 kW and 97 kW, respectively, and incorporate the latest emission reduction technology, complying with the regulations in Europe and North America for Stage IV/T4 Final engines.

ECO Mode gives up to 15% lower fuel consumption

The Stage IV/T4 Final engines are equipped with the Dynapac ECO Mode fuel saving system that minimizes fuel consumption and CO2 emissions by ensuring that the roller does not consume more power than necessary at any time. This gives up to 15% less fuel consumption and a lower noise level.
Together, optimized engines with the same compaction performance combined with ECO Mode offer substantial savings in energy and operating costs, while contributing to a “greener” soil compactor and sustainable productivity.

Same advanced features

Like the other fifth generation mid-size machines the Dynapac CA2500 and CA3500 feature cross-mounted engines, Active Bouncing Control (ABC), and advanced compaction monitoring. Extremely operator friendly, they offer unmatched ease of operation, excellent maneuverability and highest quality soil compaction.
