Since it’s founding in 1963 as a sheet metal fabrication company with five employees, SEMCO has built a reputation as a world-wide product innovator in the science of air movement, noise abatement, and air quality, with more than 300 employees and more than 300 manufacturer’s representatives.

SEMCO is a part of the Fläkt Woods Group with headquarters in Columbia, Missouri. The company operates six manufacturing facilities at the following locations:

• Morrilton, Arkansas
• Petit Jean, Arkansas
• Salisbury, Missouri
• Crossville, Tennessee
• Arlington, Texas
• Roanoke, Virginia

The facilities in Arlington, Roanoke, and Salisbury all produce high quality spiral, rolled, round, and oval duct products for commercial, architectural and industrial HVAC applications.

The Crossville facility produces acoustical panels and silencers for various markets, including HVAC, highway and cooling tower barriers, manufacturing equipment barriers, manufacturing production lines, paint facilities, acoustic barriers for sports facilities and airports, and almost any other situation where noise pollution might be a concern.

The Petit Jean and Morrilton plants fabricate packaged energy recovery equipment and desiccant-based wheel products for the commercial, industrial and institutional HVAC markets.

In addition, SEMCO also has an extensive, Columbia, Missouri based, ASHRAE 84 compliant research and development facility dedicated to the development of new products for the 21st Century and beyond.
