History

Nooter Corporation was established in 1896. Nooter/Eriksen Cogeneration Systems was established in 1987 when Eriksen Engineering (headed by Vernon Eriksen) was taken over by the Nooter Corporation. Vernon Eriksen had joined Econotherm Corporation in 1985, which became Eriksen Engineering. In the 1990s the market for heat-recovery steam generators for combined cycle gas turbines started. The company reached its peak for orders (c. 18,000 MW of plant) in 2001. Nooter/Eriksen is a subsidiary of employee-owned holding company CIC, which has investments in several different industrial and manufacturing businesses.
