Newest automatic control system for electrostatic precipitators
The best ESP control systems and user interface
FLSmidth Airtech’s PIACS® DC4 control unit for Electrostatic Precipitators (ESP) provides plant operators enhanced utilization of installed power, meaning a higher ESP efficiency and performance. The fast, powerful and energy efficient microprocessor delivers the best-in-class ESP control experience, improving the ESP performance by its fast reactions to plant operation fluctuations. PIACS® control system is used in over 3,000 ESP installations worldwide and has continuously evolved over the last 40+ years and it will continue to do so. Our controller uses a patented method to quickly detect back-corona, when dust resistivity (specific electrical resistance) is high and addresses also the process fluctuations. It features an enhanced stability monitor for ESP and process optimization. We enable superior ESP performance with improved spark detection and a patented fast voltage recovery system. Also, our controller helps you save energy using a built-in energy management control system (EMCS).
