Representatives Located Worldwide. There are two technology choices used for lowering NOx emissions: (1) front-end burner technology or (2) back-end selective catalytic reduction (SCR) technology. As air emission rulings continue to become more stringent, NOx requirements are reaching levels as low as 5 ppm NOx and are expected to decrease even further. The CataStak™ SCR system is proven technology that not only meets 5 ppm NOx, but outperforms burner technology and provides emissions limits as low as 2½ ppm NOx for many demanding applications. When compared to burner technology, the CataStak™ SCR system also provides substantial cost-savings and valuable energy efficiency gains. In over 100 installations the CataStak™ SCR system has never failed a third-party compliance test and has provided peace of mind for plant owners knowing that their system will remain in compliance year-after-year, well past any current AQMD requirements. The Nationwide Boiler CataStak™ SCR system delivers ex-ceptional performance, reliability and compliance assurance.
