CataStak™ Ultra Low NOx Solutions

With the constant evolution of Air District Regulations specifically in California, Nationwide Boiler's CataStak™ SCR system is the #1 choice for ultra low NOx compliance. Some areas of California have already implemented new, more stringent mandates requiring a NOx limit as low as 5 ppm, but the CataStak can reduce NOx emissions even further to as low as 2 1/2 ppm NOx for boilers, fired heaters, gas turbines, and other demanding applications. Don't settle for just meeting current regulations, exceed them with the CataStak and have peace of mind that you will be in compliance for many years to come.  

Nationwide Boiler's CataStak SCR system has been proven in over 200 installations throughout the country, many within the state of California. The CataStak is a versatile system that can be built in a vertical or horiztonal configuration and you have a choice between the use of anhydrous ammonia, aqueous ammonia, or urea as the NOx reducing agent. Our team of expert engineers will work with you to provide a system that fits your parameters, to your unique application requirements. Furthermore, our team is well versed on what is required to be in compliance in the most stringent locations in the state, including SCAQMD, SJVAPCD, BAAQMD, the Sacramento Metro Air District, and more.
