Tier 4-Final DD25B double-drum compactor has a Volvo D1.7A 25-horsepower diesel that does not require after-treatment. Volvo says fuel consumption is reduced 7 percent. Users can choose 3,300 or 4,000 vpm compaction, with a 39.4-inch narrow drum or a 47.2-inch wide drum. Operating weight is 5,400 and 5,779 pounds, respectively. The redesigned roller has angled drum mounts, sloping hood design and sliding seat, all of which provide a 360-degree view of the drum edges and surroundings. The pressurized water system, which Volvo says is rust-proof, delivers water to both drum surfaces to eliminate asphalt pick-up. Fine filters behind each of the eight nozzles prevent clogging and ensure the correct fan spray coverage, the company says. The lightweight hood tilts forward for wide ground-level access to engine and hydraulic components
Rear oscillation paired with front vibration is featured in the HD12VO and HD14VO double-drum rollers.
Models BW141AD-5 and BW151AD-5 double-drum vibratory compactors have been upgraded to Tier 4-Final.
