Riveer Environmental introduces the Cyclonator wheel wash, designed to prevent trucks and construction equipment from tracking dust, mud, rocks and debris onto streets. An electronic eye triggers the system as the vehicle enters, and then two 150-gpm pumps wash debris from the tires. Sludge and rocks drain into a center trough where a conveyor removes the debris, and wash water moves to nearby retaining ponds or a tank. The unit handles vehicles to 30 tons at a rate of 60 vehicles per hour.
