Electrostatic Precipitators and Insulators
Durapure
CoorsTek originally developed high-purity alumina electrostatic precipitator insulator (ESP) products in the 1960s to replace products manufactured with electrical-grade porcelain. In the early 1970s, CoorsTek commercialized high-grade alumina ceramic insulator products as the industry standard for high performance and reliable operation of electrostatic precipitator units.
Engineered to perform in extreme, hostile electrostatic precipitator environments, CoorsTek DuraPure⢠high-purity alumina ceramic works exceptionally well for discharge electrode system support insulators, rapping system insulators, feed-through bushing insulators, and anti-sway bars and insulators.
DuraPure⢠high-purity alumina ceramic offers higher quality material properties than electrical-grade porcelain in ESP applications, including:
Alumina Reliability
Better wear resistance
Higher volume resistivity
Greater mechanical strength
More chemically inert
Increased Value
By using the advanced material properties of alumina, each electrostatic precipitator component will be able to:
Last longer
Lower maintenance
Increase reliability
Reduce costs
