Electrostatic precipitator

The KMA plate filter ensures effective filtration of production exhaust

Electrostatic precipitator

The 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 extract greasy, oily or pasty particles and aerosols from the exhaust air stream through targeted electrostatic charging, which requires only a low energy input. Each of the KMA high-performance electrostatic precipitators delivered worldwide is manufactured 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 using little energy input. The resulting charge difference forces dust particles, smoke, aerosols or other impurities in the incoming exhaust air to the collector plates. There the impurities accumulate. Afterwards, the purified exhaust air flows through further filter components or is transferred via ventilation systems.

Thanks to its efficient technology, KMA electrostatic precipitators achieve a separation efficiency of up to 99.8%. To purify an exhaust air volume of 5000 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. Thus, the KMA electrostatic precipitator is an energy- and cost-efficient alternative to conventional filter systems, such as the fabric filter.

Dust and particle separation through ionization

How does the KMA electrostatic precipitator work?

The electrostatic precipitator can achieve a high degree of separation performance with low energy input. The mode of action is copied from nature and is similar to the cleaning effect of a thunderstorm: dust and other particles are charged by ionization and then knocked down.
