Ionizer-Collector Cell

Power Pack

How ESP’s Work


• High voltage power supply– transforms & rectifies 115/230 Vac input to dual output of

(+)12.0 / 6.0 kVdc• Ionizer - collector cell

– powered by the kVdc from the high voltage power supply– 1st stage: ionizer (+) 12.0 kVdc charges particles– 2nd stage: collector (+) 6.0 kVdc charges alternate plates

repel the (+) particles, grounded plates attract and retain the particles

How ESP’s Work


Kitchen Exhaust The Contaminant

• Particulate - Smoke, Grease, Water– Size ranges from <0.01 to >20.0 µm– Loading up to 50 mg/m³– Goal usually 95% removal

• Filtration Options– Fiber Filter - variable resistance & eff., high maintenance– Wet Scrubber - high cost , low eff.– Incinerator - high initial & operating cost– Electrostatic Precipitator (ESP)


ESP’s Benefits Over a Filter Box

• Particulate - ESP- High and constant efficiency- Low and constant resistance to airflow- Permanent collector- Built-in cleaning system
