SCHOFIELD — Officials from Greenheck announced this week that the company will invest $19 million in an expansion project that will add 111,500 square feet to several Greenheck manufacturing and shipping facilities in Schofield and Mosinee.

“Demand continues to increase all over the world for Greenheck products, and to keep up we need to expand our production capacity and capabilities,” said Dave Kallstrom, president of Greenheck’s Global Ventilation Solutions division. “We’re delighted that our board of directors decided to make this economic investment here in our hometown. It’s a great way to celebrate our 70th year in business in Schofield. These expansion projects will not only create local jobs during the construction process but also future opportunities in our local production facilities and offices at Greenheck.”

Construction will begin in August on a 34,000-square-foot addition to Greenheck’s National Distribution Center and on a 20,000-square-foot addition to the company’s Mosinee damper facility.

A new 50,000-square-foot facility near the Schofield main plant will also be built to expand Greenheck’s fan production.

Additional upgrades, expansions and renovations will take place during the next two years at Facility 2, the company’s primary manufacturing plant in Schofield.

Greenheck, which manufactures and distributes air movement, conditioning and control equipment, is headquartered in Schofield. The company began operations in Schofield in 1947.

The company employs over 3,300 people worldwide, including 2,100 in Wisconsin, according to a company news release.
