Air Techniques is proud of its history designing steel stack systems and the componetry, equipment and facilities related to the stack systems. From the first stack over 25 years ago to the current stack projects, our design engineering and project engineering are the focal point of the stack business. The engineers of ATI and of our sister company, AERI, work together to provide safe, efficient and cost effective steel stack systems for industry. From small diameter boiler economizer supported stacks to large 14 ft. diameter 250+ foot tall major stack projects, ATI engineers are known for their quality, conservative designs. In addition to stacks and stack accessories, our engineers frequently design foundation systems for these stacks and when required, pile systems that work with the stack foundations or pile caps. When support towers are combined with stack structures, our design team of the Zarrabi brothers, Ken and Nader, make it happen. The elder Ken and the younger brother, Nader, graduated from Georgia Tech in structural engineering. Ken completed his masters later at MIT. Both are active in various engineering associations. Nader is chair on a number of committees on the ASME Steel Stack Code. Nader has been an active ASME participant for more than 10 years. ASME acknowledged Nader’s contributions and outstanding achievements recently with the attached Certificate of Achievement Award. When you purchase an Air Techniques stack, you can trust you have had one of the best design teams available perform your design.
