The private equities firm Wynnchurch Capital has acquired Boss Industries of LaPorte, whose facility is pictured.

LaPORTE — A LaPorte manufacturing company has been acquired by a Chicago area equity investment firm.

Boss Industries, a maker rotary screw power-take-off compressors and vapor recovery systems for utilities and municipalities, is now owned by Wynnchurch Capital.

The sale price was not disclosed. Future plans, and whether the number of jobs will be impacted, were also not revealed.

Rosemont-headquartered Wynnchurch's strategy is partnering with middle market companies in the U.S and Canada that it believes possess the potential for substantial growth and profit improvement, according to the company.

Infra Pipe Solutions, a Canadian manufacturer of large diameter, high density polyethylene pipe, and Logistik Unicorp, a leader in managed clothing services and uniform solutions also based in Canada, are among other companies recently acquired by Wynnchurch.

Wynnchurch lists $2.2 billion of committed capital under management. It said it has made its recent purchases, including of Boss Industries, from a $1.3 billion investment fund.

"Wynnchurch understands the demanding needs of our customers and has the resources and expertise to help take our company into a new phase of expansion," Boss Industries President Todd Hudson said.

Boss Industries was founded in 1988 and accounts for more than half of all power take-off rotary screw compressor sales, according to the company.

It operates from a 50,000 square foot facility on a 10-acre lot at the Thomas Rose Industrial Park on the city's east side.

"Boss has built a market-leading reputation that uniquely addresses its customers' needs through innovative design, proven quality and unmatched reliability. We are excited to partner with Todd and his team to build on the company's impressive track record of growth," said Paul Ciolino, operating partner at Wynnchurch Capital.
