Incorporating discharge electrode technology, HEI (High Energy Ionizer) Wet Electrostatic Precipitator (WESP) System concentrates ionizing corona in strategic areas within collecting tubes. Resulting particle charging fields, which are optimized in terms of strength/degree and migration velocities, help minimize precipitator size. With gas capacities from 1,000–300,000 acfm, system incorporates Ultimix™ Conditioning System, RotaBed™ Pre-Scrubber, and PLC-based voltage and spark controls.
