Twenty Years Specializing in Air Pollution Control by Catalysis, SCR NOx Reduction, and Platinum Group Metals Technologies and Markets. Our Materials Characterization and Catalyst Development Laboratory performs Novel Research, Benchmarking and Catalytic Activity Testing.

SCR System Experience

With over 20 years in the SCR service industry, Environex has extensive experience with many varied types of SCR systems. Our experience includes SCR installations on boilers, turbines, IC engines and refineries and with all major catalyst types. While SCR is our specialty, we deal with all types of stationary source emission control catalysts including VOC and CO removal and three-way catalysts (TWC).

As leaders in SCR testing services, our extensive database of catalyst performance data from all major commercial catalyst vendors allows us to evaluate problems from a unique perspective. Our years of providing solutions in the areas of design and problem solving allows us to work seamlessly with a majority of the catalyst vendors and end users throughout the country.
