LOS ANGELES AND DES PLAINS, IL–(BUSINESS WIRE) – Partner of Angeles Equity Partners, LLC (“Angeles”) has acquired Data Clean, LLC (“Data Clean”), a provider of specialized contamination control and remediation services for critical environments. Angeles will partner with Data Clean’s previous owners, Richard Hill and Dean Sirakides. They will retain an ownership stake in the company and are focused on executing a buy-and-build strategy in the critical pollution control sector.

Headquartered in Des Plaines, Illinois, Data Clean provides mission-critical contamination control and abatement services for data centers and other telecommunications facilities (through its Data Clean-branded division) and biopharmaceutical and life sciences cleanrooms ( through its Sterile Science brand division).
