What The Dupps Co does

The Dupps Company is a family-owned (five-generation) industrial equipment manufacturer founded in 1934 and headquartered in Germantown, Ohio. It designs, builds, and services capital equipment that converts animal by-products and other protein-bearing feedstocks into rendered protein meals and fats, serving customers in the rendering, fishmeal, oil seed, and insect-protein segments worldwide. Core product lines include cookers, dryers, screw presses, centrifuges, decanters, automated process control systems, and NIR-based real-time compositional analyzers developed in partnership with Carl Zeiss Spectroscopy; the firm holds granted and pending patents on screw-press components (Tuff-Cast Screw Press Flights; HCPR Screw Shaft) and maintains ISO 9001/2008 certification for its centrifuge line.

The business model blends long-cycle equipment sales with a high-recurring aftermarket: capital-equipment projects drive installation and integration revenue, while a six-center U.S. field-service network, route-truck parts logistics, the Sunrise USA and Universal Maintenance subsidiaries, and customer-training programs (Dupps University, Dupps Customer Toolbox) capture ongoing parts, service, and consumables revenue from the installed base. International reach is delivered through Dupps do Brasil (manufacturing), distribution partners Mavitec (Netherlands), Akane (Japan), and Keith Engineering (Australia), plus Mexican distribution, giving the company a multi-region service and supply footprint. Operational moves over the past decade — acquisitions of Clapper Corp (2017), Universal Maintenance USA (2021), and Sunrise USA / Sunrise Equipment (2021), and the 2024 expansion of a new 48,000 sq ft Germantown manufacturing and technology facility plus a new Oklahoma City service center — point to a strategy of consolidating the niche rendering-equipment supply chain and converting installed base into recurring service and instrumentation revenue.
