Advanced SCR Solutions for Data Centers
CataStak SCR Systems

Data centers are the backbone of today’s digital economy, powering everything from cloud computing to AI-driven applications. However, the energy systems that keep these facilities running—boilers, turbines, heat recovery steam generators (HRSGs), and reciprocating engines—produce emissions that must comply with increasingly stringent environmental regulations.

Nationwide Boiler’s CataStak™-DC Selective Catalytic Reduction (SCR) system builds on the proven success of our CataStak technology, which has been deployed across industrial plants, utilities, and power generation facilities nationwide. With thousands of operating hours and documented performance, CataStak systems consistently achieve ultra-low NOx levels, often as low as 2.5 ppm, while maintaining system reliability and efficiency.

The CataStak-DC solution is engineered specifically for the unique demands of data centers, offering a compact, modular design that integrates seamlessly with existing infrastructure. Utilizing advanced catalyst technology and under precise ammonia injection control, the system ensures optimal NOx reduction without compromising uptime—a critical factor for mission-critical operations.
