Electrostatic Precipitators & Insulators

Durable and Reliable Electrostatic Precipitator Components

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.

Alumina reliability

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

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

electrostatic insulator (ESP) applications

Providing maximum strength and volume resistivity, even at high temperatures for prolonged periods, DuraPure high-purity alumina ceramic is the insulator material of choice a wide range of environmentally regulated industries:
