In 1928 Earle C. Reed established two manufacturing companies, the Utica Companies and the Dunkirk Radiator Corporation. Over time these companies acquired other heating and cooling companies, including Pennco, which Dunkirk purchased in 1998. In 1999, Dunkirk and Utica merged to form ECR International, “ECR” referring to the initials of founder Earle C. Reed.
In 2008 ECR built a 25,000 square foot stamping plant with new manufacturing equipment at the Dunkirk facility and expanded the Utica faciliity by 30,000 square feet.
