Sentinel Capital Partners acquires NSI Industries


New Platform Builds on Firm's Experience with Branded Electrical Products


NEW YORK, November 18, 2024 – Sentinel Capital Partners, a private equity firm that invests in promising midmarket companies, today announced the acquisition of NSI Industries, a market-leading provider of branded products for the electrical and HVAC markets. Terms of the deal were not disclosed.

NSI comprises two divisions, electrical and HVAC, that sell through third-party distributors and have strong manufacturing capabilities. The electrical division's iconic brands–among them, Bridgeport, Polaris, and Tork—are coveted by electrical contractors for superior durability, reliability, and functionality. Electrical products include insulated connectors, fittings, wire management products, fiber assemblies, and other high-value-add components with replacement-driven demand. In NSI's HVAC division, leading brands Duro Dyne and Supco, well known for excellent product quality and customer service, provide critical HVAC components used by contractors and installers, including hanging systems, fasteners, and air regulation accessories. NSI has enjoyed impressive and consistent sales growth across its two divisions.

"NSI has a long record of success with a strong foundation of great brands in place for future growth," said John Van Sickle, a Sentinel partner. "We're excited to partner with NSI and its talented management team."

"We firmly believe that Sentinel is the right partner for our company in this new chapter," said NSI's CEO, G.R. Schrotenboer. "Their expertise and resources align perfectly with our vision for growth and innovation. Together, we are poised to elevate NSI to new heights, delivering exceptional value to our clients and stakeholders."

Sentinel's expertise in electrical manufacturing and distribution includes ECM Industries (electrical products for construction, irrigation, landscape, and utility markets) and Power Products (diversified electrical products). Sentinel's broader expertise in industrial manufacturing and distribution includes investments in Chromalox (electric heating products and systems), Engineered Controls (pressure regulators, valves, and controls), LTI Boyd (engineered sealing and thermal management components), RotoMetrics (rotary tooling products), Sonny's (conveyorized car wash systems), and Spectrum Safety Solutions (fire detection and suppression products).
