In 1999 we saw the first demonstration project of an SCR system for ultra low NOx performance and in 2001 Nationwide Boiler announced the CataStak SCR System, proven to reduce NOx emissions by as much as 90%.

The CataStak is a portable, low-temperature selective catalytic reduction (SCR) system consisting of a single-reactor housing with low temperature catalyst and an ammonia (aqueous or anhydrous) or urea (diesel exhaust fluid) injection option. This technology not only meets 5 ppm NOx, but outperforms burner technology and provides emissions reductions as low as 2 ½ ppm NOx. Advantages of the system include:

  • Easy field retrofit – no burner or fan changes required
  • Ammonia-free option – no special permits required
  • Low operating cost • Stand-alone operation – minimum operator intervention
  • Dramatic reduction in stack emissions – NOx, VOC & CO

In over 100 installations, the Nationwide Boiler 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.

Contact Nationwide Boiler today to learn how you can decrease your facility’s operating costs and lower your carbon footprint with a CataStak SCR System.

The state of California, home to Nationwide Boiler, is one of the most stringent states in regards to air pollution and emissions requirements. Some places, including the South Coast Air Quality Management District (SCAQMD), require boilers to have NOx emissions of 9 ppm or less! Luckily, Nationwide Boiler offers a complete line of ultra low NOx mobile boiler rooms, pre-permitted for use in the SCAQMD. These mobile boiler rooms include firetube boilers from 47.5 hp to 650 hp with ultra low NOx burners emitting no more than 9 ppm NOx. And for larger steam capacity needs, Nationwide Boiler can provide a larger watertube boiler with CataStak SCR System for 5 ppm NOx compliance.

If you are in the SCAQMD and need a rental boiler in a hurry, look no further! Contact Nationwide boiler today at 1-800-227-1966.

In the early 1990's emissions regulations began to change dramatically. In 1995, Nationwide Boiler became the first and only company to convert our entire boiler rental fleet to 30 ppm low NOx. Since then, emissions requirements have continued to change and NOx numbers have reached as low as 7 ppm in some areas.

Nationwide Boiler strives to stay up-to-date with the most stringent of those requirements by stocking equipment that can meet or exceed the permit requirements in most areas. We have a variety of firetube boilers that will meet 9 ppm NOx emissions and are pre-permitted for use in the South Coast Air Quality District in California, one of the more stringent air districts around. Additionally, Nationwide Boiler can supply our exclusive CataStak Selective Catalytic Reduction System (SCR) for as low as 2.5 ppm NOx on most of our rental equipment, both firetube and watertube boilers.
