Charlotte, North Carolina-based private equity firm Ridgemont Equity Partners has closed a majority investment in Abrasive Products & Equipment. Abrasive Products, headquartered in Deer Park, Texas, distributes surface preparation, remediation, abatement, safety, environmental and waterjet cutting products. The company operates through four business units – Abrasive Products & Equipment, BKW, SharpJet and SafetyPros – that service the petrochemical infrastructure, offshore drilling, shipyard operator, oil and gas infrastructure, manufacturing health care and government sectors. Terms of the deal were not disclosed. Ridgemont says the deal is a fit because of the firm’s Gulf Coast focus. Abrasive Products has 14 locations in the Gulf Coast and Mid-Atlantic region. In June, the firm’s portfolio company, J.A.M. Distributing Co. agreed to buy Jones Oil Inc., which does business as High-Tech Equipment. The firm closed its first fund in April 2013 with $735 million in commitments. Ridgemont generally invests between $25 million and $75 million in health care, energy, industrial, technology and telecommunications companies. BlackArch Partners acted as Abrasive Products financial adviser. Madison Capital Funding, NXT Capital, TIAA-CREF and Stellus Capital Management provided debt financing for the transactions. Alton & Bird LLP provided legal advice to Ridgemont.
