SR-SERIES WJ160 root-control equipment from ID-TEC produces 15,000 psi to cut through thick roots without damaging pipe surfaces. It is easily attached to the base robot, which operates in 7-inch and larger relined pipelines. It has a precisely aimed cutting nozzle, camera and high-power LED lighting. Water is pumped under pressure through the nozzle, where the resulting blast is aimed directly at the root intrusion. Smaller root branches and dirt are flushed away with pressures up to 5,000 psi. Then the main root is cut off where it enters the pipe. Pressures up to 15,000 psi make the equipment fast and able to cut through main roots up to 5 inches thick. Step-less pressure adjustment and precision ensure that only the undamaged and cleaned pipeline remains after the operation. 503/504-8474; www.sr-series.com.
