Electrostatic precipitator for flue gas cleaning
Achieve industry-leading particulate removal from flue gases with advanced electrostatic precipitators, designed to ensure high efficiency in cleaning operations while managing sub-micron particulates and aerosols in diverse industrial applications.

The Electrostatic Precipitator (ESP) from GEA efficiently removes particulates from industrial flue gases utilizing electrostatic forces. Available in both dry and wet configurations, GEA’s ESPs are tailored for applications ranging from cement production to chemical processing. They offer remarkable separation efficiency, capturing over 99.9% of particulates and accommodating continuous, high-temperature operations up to 450°C. The dry ESPs use optimized inlet transitions and deflection plates for even gas distribution, ensuring maximum collection efficiency with minimal maintenance interruptions. The wet ESPs excel in handling sub-micron particulates and aerosol-laden gases like exhaust from lead and tar operations, with an integrated scrubbing section for acid gas removal. All units are PLC-controlled for automated, seamless integration into existing systems, and are designed for energy efficiency with low-pressure losses. Fabricated in corrosion-resistant materials, these systems meet stringent environmental compliance standards, ensuring long service life and reliability in high-demand environments.
