Buffalo, New York – TriStar, LTD., announces the introduction of its new EDG-trac Knife Advance System for Pre-Coat Rotary Vacuum Drum Filters (RVDF). The Encoded Digital Guidance (EDG) system is designed to improve filtration performance and reduce energy costs. TriStar states that it will rebuild or remanufacture existing RVDF units at its facility or retrofit the EDG-trac system to an RVDF at a customer’s plant.
According to the company, the EDG-trac system removes as little as 1.4 thousandths of an inch per revolution at a drum speed as low as 0.2 RPM. This extends pre-coat life by not cutting away clean pre-coat while maintaining acceptable solids separation and improving liquid throughput.
EDG-trac also features a highly efficient, single-motor VFD to reduce energy use and cost. A fully automated PLC controls the advance speed, retract speed, and drum speed, allowing precise control and providing valuable information to operators, the company states. An automatic high-speed retract mode reduces time between cycles and allows the filter to be recycled and put back online quickly.
