Data Clean Corporation has acquired another data center cleaning business.

Angeles Equity Partners-owned company this week announced the acquisition of DP Guardian, Inc., a Colorado-based provider of critical environment cleaning services and installer of airflow containment systems for data centers.

The terms of the transaction were not disclosed.

Headquartered in Denver, DP Guardian has provided data center critical environment cleaning and airflow containment services since 1992.

“Partnering with DP Guardian is a significant milestone for Data Clean as we expand into Denver and the Mountain region,” said Rich Hill, president of Data Clean. “DP Guardian is well-established in the critical cleaning industry, with a long-standing history of commitment to their customers and employees that perfectly aligns with Data Clean’s values.”

DP Guardian CEO Jon deRidder added: “Data Clean is the ideal partner to provide us with the resources and support to capitalize on the next generation of opportunities created by AI-driven demand, edge computing growth, and cloud capacity expansion.”

The transaction marks Data Clean’s third acquisition since it was acquired by Angeles Equity Partners in November 2022.

Data Clean was founded in 1979 and offers specialized facility maintenance services. The company is based in Illinois but also has branches in Canada, Hong Kong, India, Mexico, Saudi Arabia, Singapore, and the UAE. The company lists Meta, Microsoft, Apple, Google, and NASA as among its customers.

The company acquired SML Enterprises in June 2023 and Sealco LLC in November 2023, two other critical environment cleaning businesses serving data centers in the US.

Angeles Equity Partners is a lower middle-market private equity investment firm that focuses on underperforming industrial businesses.

“The combination with DP Guardian accelerates Data Clean’s strategy to expand its service offering and geographic reach within the critical environment cleaning sector,” said Frank Spelman, managing director at Angeles Equity Partners. “We are excited about the prospects for Data Clean given the rapid growth occurring in the data center space. As data centers continue to scale, and their complexity increases, the need for a sophisticated, critical contamination control provider with a national presence is clear.”
