Neptune Roller systems are the ideal answer for sites with extremely cohesive soils. The systems are a one piece integrated system that is available with or without a scraper conveyor to continually evacuate the solids. Unlike the drive- through systems, the Roller system is designed to clean the tires, axle by axle, while holding the vehicle in a stationary position. This unique method allows the Neptune Roller System to deliver an unlimited number of tire revolutions. The control panel is used to configure the correct number of revolutions.
