Wet Electrostatic Precipitators (ESPs)

We have developed a wet ESP system for applications involving sticky or flammable particulate. A washdown system keeps the ESP internals clean to help prevent fires and maintenance problems. Our durable wet ESP systems have solved difficult emission control problems for fiberglass forming and curing ovens, wood dryers, wood-fired boilers, and steel scarfing processes.

  • Wood dryers
  • Wood-fired boilers
  • Steel scarfing processes
Mobile ESP Testing

McGill AirClean's mobile ESP can be used to study an emission problem on site and develop an effective solution. This equipment enables the company to analyze the flue gas stream, determine ESP collection efficiencies, and collect data to size a full-scale wet or dry ESP for a customer's application.

Mobile testing helps us size the full-scale system to satisfy your performance requirements. We will design an efficient, economical, properly sized system that will be large enough to handle your volume flow, yet not have more capacity than you need. A properly sized system can save you a substantial amount of money in equipment, installation, and operating costs. Should your requirements ever change, McGill AirClean's modular design makes it easy to add to the system.
