“With the addition of UPC, Micronics Holdings has significantly grown its dry filtration business, increasing its ability to meet the service and aftermarket needs of its customers,” said Richard Crowell, Managing Partner at Vance Street Capital.

“Working closely with portfolio companies such as Micronics to source, close and integrate strategic add-on acquisitions that allow our portfolio companies to accelerate their growth is central to our investment strategy.”

“The addition of UPC allows us to better meet our aftermarket customers’ needs for engineered and technically complex mechanical repairs to their existing dry filtration systems,” said Micronics President and CEO Rick Weiler.

“This transaction also expands our presence on the east coast and in the southern portion of the United States. Working together, I am confident we will be able to achieve significant growth while also providing our customers with outstanding service.”
