This project included the largest AHU that TEC has ever sold and one of the largest in the United States. It shipped to the jobsite in sections on approximately 24 seperate trucks. The AHU, which now sits on the top of this 568 ft. skyscraper, added two stories to the building structure. The Temple itself was once the tallest skyscraper in Chicago from 1924 to 1930. Check out some of the photos of the crane lift and Hill Mechanical assembling the AHU.
