What Stelter & Brinck does

Stelter & Brinck, Ltd. is a privately held, third-generation family-owned industrial OEM founded in 1922 in Harrison, Ohio. The company designs and manufactures custom industrial process heating, combustion, and environmental equipment, including direct and indirect fired air heaters, thermal and catalytic oxidizers, packaged combustion systems, valve trains, control panels, and a dedicated metals-industry product line (ladle and tundish preheaters, sow dryers, scrap preheaters, paste heaters, and SEN/SES preheaters). All equipment is custom-engineered per application and test-fired at the company's factory before shipment; the indirect-fired air heater (IAH-R) is USDA Dairy accepted, and the company's welding and panel fabrication is certified to AWS D1.1/D1.3/D1.6 and UL 508A, with FM, CE, NFPA, CSA, and GAP builds available on request.

The company operates a direct sales model with a global footprint — equipment is installed worldwide across small family-owned plants through Fortune 100 industrials — and monetizes across three streams: (1) one-time sale of custom engineered equipment (quote-based, multi-year project contracts), (2) hardware parts sales (many items stocked in-house with same-day shipping), and (3) recurring combustion field services including the Scheduled Burner Maintenance Program (SBMP), start-ups, tuning, and upgrades/retrofits. Customer verticals span industrial manufacturing (drying, curing, heat treating, ovens), metals (aluminum/steel), food/pharmaceutical/dairy, and environmental/emissions control. No APIs, software platforms, or AI/ML products are disclosed; the business is a traditional industrial hardware and services operation.

Stelter & Brinck's value proposition centers on 100+ years of process heating expertise, custom engineering, in-house test-firing, low and ultra-low NOx emission options, and documented customer outcomes including up to 90% thermal efficiency, up to 40% fuel reduction, 99.9% VOC destruction, and 65–70% reductions in utility usage and downtime. The company is privately held with no disclosed external investment, parent, or M&A activity, and operates with a small headcount of 11–50 employees supported by global field service technicians.
