The Vacall AllExcavate hydroexcavator provides operating efficiency and cost control for excavating around water and sewer lines and other underground utilities. The design uses a chassis engine to provide power for vacuum and jetting functions, slashing fuel consumption, eliminating emissions from a second engine, and reducing costs and downtime for routine maintenance. It has a high-pressure water system with rheostat control to vary water volume and capacity output. A heated compartment encloses the water system to protect components against freezing. Water tanks are made of high-quality aluminum for extra strength. The AllSmartFlow intelligent control system enables precise adjustments in boom movement. It has double-cyclone filtration with a simplified design to reduce maintenance, extend performance and increase working life. Its rear-mounted boom front-loads debris. An optional cold weather package includes heated cabinetry that encloses the boiler, warming the water when temps drop below freezing. 330/339-2212; www.vacall.com.
