The Volvo DD31HF and DD38 HF double drum high-frequency asphalt compactors are powered by a fuel-efficient, liquid-cooled Kubota 44-horsepower (32.8-kilowatt) diesel engine. The Kubota features standard glow plugs for more reliable startups. The DD31HF and DD38HF compactors have operating weights of 6,840 pounds (3102 kilograms) and 8,400 pounds (3809 kilograms), and drum widths of 49.2 inches (1250 millimeters) and 54.1 inches (1375 millimeters), respectively. Both units feature a large, 79-gallon (299-liter), rotationally molded, polyethylene water tank. This tank provides extended intervals between refills. The standard pressurized water system is dual filtered and equipped with five hand-serviceable water nozzles for each drum. When set to the automatic mode, waterflow is activated only when the machine is in motion further extending refill intervals.
