Flakt Woods has extended its American presence by buying Semco for an undisclosed fee.
The firm has 400 employees in eight locations in the US.
Semco provides products and service for ventilation and air treatment, and reports annual sales of approximately $65 million.
The company also sells energy recovery systems using desiccant wheels, and supplies of round and oval duct systems.
“We are very pleased to welcome the talents of Semco to join the Flakt Woods Group, and view this as a significant step for us in North America within the air climate for buildings sector.
“To date, the Group’s activities in the US have been focused on fans through the American Fan Company, and the acquisition of Semco is a perfect illustration of the new development strategy we intend to pursue with our new owners to extend our portfolio of air climate and air movement solutions worldwide,” said Didier Forget, CEO of Flakt Woods.
