Precipitator Seal Air System
The penthouse or insulator compartment pressurization system is a vital operating link
in your electrostatic precipitator. Its function is continually maintaining a pressure
in the top housing(s) that is higher than the operating pressure of the precipitator.
This prevents the accumulation of dust and moisture on the support bushings and rapper
insulators. If an accumulation of dust and moisture does occur on the support bushings,
they will lose their insulating quality and short out the bus section.
Hamon Research Cottrell strongly recommends that the pressurization fans, heaters, dampers,
filters and controls be inspected regularly to prevent unnecessary down time. If routine
inspections identify accumulation on the insulators, an evaluation of the seal air system
may be in order.
