Electrostatic precipitator cell

A KMA electrostatic precipitator contains numerous electrostatic precipitator cells. Each electrostatic precipitator cell consists of an ionization electrode, the so-called ionizer, and two collector plates. Electrostatic precipitator cells purify the exhaust air flowing past from greasy, oily or pasty particles or aerosols by means of targeted electrostatic charging, which requires only a low energy input. Each of the KMA high-performance electrostatic precipitators delivered worldwide is manufactured in its patented design in the KMA filter factory at the production site near Bonn, Germany.

How it works: Inside the electrostatic precipitator an ionization electrode generates a strong electric field while keeping energy consumption low. The resulting charge difference forces dust particles, smoke, aerosols or other impurities in the incoming exhaust air to the collector plates. This is where the impurities accumulate. Afterwards, the purified exhaust air flows through further filter components or is transferred via ventilation systems. Thanks to its efficient technology, the KMA electrostatic precipitators achieve a separation efficiency of up to 99.8 %.

To purify an exhaust air volume of 5,000 m3/h an electrostatic precipitator cell requires the approximate energy consumption of a 100 W light bulb. The innovative KMA filter cleaning system (CIP) removes the accumulated impurities inside the electrostatic precipitator cell at regular, intervals similar to a dishwasher. This eliminates the need for filter replacements.

To meet the requirements of different application areas, KMA electrostatic precipitators are available in two different designs: the tube filter which is mainly used in smokehouses, and the plate filter for all other industries.
