Customer Testimonials

"Our CataStak™ SCR system passed our source test at 5 ppm NOx and no more than 3 ppm NH3. I'm so glad we went with this instead of a low NOx burner. The unit does everything it is supposed to do and more."
Leland McPherrin, Plant Engineer, H.J. Heinz Company

"The CataStak™ SCR unit was very easy to install, easy to operate, and easy to maintain. Overall, it is a totally painless way to meet difficult emission requirements."
Gordon Judd, NRG Energy Center

"The CataStak™ SCR system allowed us to easily meet the stringent emission requirements of our local air board. It ran very reliably during the entire project."
Rick Bonner, Utilities Area Manager, Tesoro, Golden Eagle Refinery
