CataStak SCR Systems

The CataStak™ SCR system was originally tested on numerous watertube boilers in Nationwide Boiler's rental fleet and is proven to reduce NOx emissions by up to 99%. As a proven solution for NOx emissions reduction, the CataStak also provides increased operating efficiency, better turndown than ultra low NOx burners, and versatility. The CataStak™ can easily be retrofitted on any existing system in a veritcal or horizontal configuration, and with the option of anhydrous ammonia, aqueous ammonia, or urea as the NOx reducing agent (reagent). 

Today, the CataStak SCR system has been installed in over 200 applications, ranging from package boilers, fired heaters, gas turbines, and more.
