Precipitator Seminars



APC Network


Precipitator Seminars offers both public and in-house seminars in electrostatic precipitation. The primary objective of these seminars is to teach attendees how to better evaluate, operate, maintain and improve the performance of existing precipitators. Emphasis is on developing a practical understanding of the basic factors and determinants of precipitator operation and performance.
