Greenheck is known worldwide as the leading manufacturer of air-movement and control equipment. Its flagship ventilation products are typically found behind walls, in ductwork or on the roofs of hospitals, office buildings, hotels, shopping malls, restaurants, schools, industrial plants and other commercial buildings. Their function, basically, is to move air in, out and around a building — making life inside a lot more pleasant.  Greenheck is also a major, multi-brand corporation, representing a number of other affiliated entities (Accurex, Airolite, Innovent, Precision Coils, and Valent) offering architectural louvers and sunshades, specialized air-handling systems, heating and cooling coils and many related accessories and services. (See Other Greenheck Corporate Brands.)  It’s clear Greenheck has come a long way since 1947 when it began business as a tiny sheet metal shop in Schofield, Wisconsin. Today, Greenheck brand fans, energy-recovery ventilators, packaged ventilation, make-up air units,  dampers, louvers, kitchen ventilation systems, laboratory exhaust systems, and coils are shipped around the globe. Most of the company’s manufacturing still takes place in Schofield; additional manufacturing and assembly facilities are located in California, Kentucky, North Carolina, Mexico, and Delhi NCR Region, India.  Bob and Bernie Greenheck Bob and Bernie Greenheck Founders Bernie and Bob Greenheck, though always determined to make their business grow, never imagined how large their enterprise would someday become. And grow it has. No other company offers a wider selection of these products.
