Construction of a new $10 million Spray Dynamics manufacturing facility in the Union Development Center is underway and going well, said General Manager Luke Bell.

The St. Clair company was acquired by Heat and Control, headquartered in Hayward, Calif., in 2011.

“Since we were acquired in 2011, we have seen over 100 percent increase in growth both from a sales and an employee standpoint,” Bell said.

When the company was bought, there were 28 employees. That number has expanded to 54 employees, with no room for further expansion until moving into the new facility.

In an agreement made to help the city fund a roadway in the center, the company agreed to hire 10 people in the first two years and has already hired five new employees. It will have the ability and space to expand to 100 employees, staggering hiring over several years, Bell noted.

The company broke ground on the new site in November 2016.

Bell said finding a site to build near its current location was important to owners, who wanted to minimize the driving for current employees, who will remain at the company.

The Facility

The building will be located on a 13.32-acre green field site and the total manufacturing and office areas will total approximately 103,000 square feet. The project has been engineered by Washington Engineering & Architecture Inc. and is expected to be completed by December.

This new facility will offer the latest in manufacturing capabilities, modern office and engineering space, product testing rooms and also allows for future site development, Bell said.

A key feature of the new facility is a demonstration/trial center that will provide comprehensive testing capability across a wide range of Heat and Control products. It will offer the ability to test an integrated line of processing, conveying, coating and packaging equipment.

The Korte Company, St. Louis, is running the job site.

So far, plumbing and foundation have been completed, with metal for the structure to arrive in the coming weeks, Bell said.

“We have a good team,” he said. “The Union Development Corporation and the city of Union have gone above and beyond to introduce us to the community and to make sure we’re comfortable.

“They’ve been transparent with the process and made us feel welcome,” he added. “They’re making sure everything goes as smoothly as it can.”

“I’m very proud,” Bell said of the new facility. “I’m excited about Heat and Control investing back into the Spray Dynamics brand name, as well as reinvesting into the facility to expand our growth in Spray Dynamics and Heat and Control.”
