Dry and Wet Electrostatic Precipitators (ESPs)

GE offers a wide range of robust, cost-effective, and reliable electrostatic precipitator designs for a variety of applications. Discover the advantages of our electrostatic precipitators.

Proven particulate matter removal

Less than 10 mg/Nm3 emissions.

Designed for Performance

Excellent and efficient electrostatic precipitator with lower cost modular systems.

For Wet Electrostatic Precipitators

Ultra-low particulate emissions (less than 1mg/Nm3), acid mists, aerosols, and hazardous air pollutants (HAP).

Backed by more than 237 GW installed in power generation and more than 70 years of experience on an extended range of fuel combinations and industrial applications, our electrostatic precipitator solutions cater to increasingly strict regulations at a lower life cycle cost.   

We offer spiral and rigid designs of emitting electrodes, tumbling hammer, and electric impact rapping systems. Our ESP pollution control devices feature a flexible layout and modular designs. GE also offers integrated ESP control systems, including the latest generation EPIC intelligent controller and the ProMo tool for enhanced ESP performance.

As an alternative to Transformer/Rectifier (T/R) sets, GE also provides Switch Integrated Rectifiers (SIR) for increased power input, lower power consumption, and improved particulate removal efficiency. Our SIRs work well for performance enhancement of existing ESPs.
