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:
- Better wear resistance
- Higher volume resistivity
- Greater mechanical strength
- More chemically inert
By using the advanced material properties of alumina, each electrostatic precipitator component will be able to:
- Last longer
- Lower maintenance
- Increase reliability
- Reduce costs
