Angeles Equity Partners, a lower middle-market private equity investment firm, has bought Data Clean LLC, a contamination control and removal services company.

Data Clean, headquartered in Des Plaines, Ill., offers its services for data centers and other telecommunications facilities through its Data Clean brand, as well as biopharmaceutical and life sciences cleanrooms through its Sterile Science brand. Data Clean provides recurring maintenance and pre- and post-construction decontamination services for a nationwide, blue-chip customer base. Through this partnership, Data Clean aims to pursue organic and inorganic growth initiatives, looking to increase its market share.

“The heightened scale and complexity of data centers and other critical environments has increased demand for sophisticated, national providers of contamination control services,” says Richard Hill and Dean Sirakides, president of Data Clean and president of Sterile Science, respectively. “Our partnership with Angeles enables us to expand our market-leading service offering alongside the growing needs of our customers.”
