Precipitator to Fabric Filter Conversion

For a vintage electrostatic precipitator that needs to be rebuilt or replaced, installing a Pulse Jet Fabric Filter in the existing casing(s) can often be a cost effective option to provide a substantial increase in particulate collection efficiency and consistent high removal rates for mercury control when coupled with a sorbent injection system.

Buell APC has the expertise to custom engineer and provides its intermediate pressure long bag pulse jet technology to convert any OEM ESP Design.
