What Jeremias does

Jeremias is a family-owned, German-founded manufacturer of stainless steel chimney and exhaust systems, established in 1974 and headquartered in Wassertrüdingen, Germany, with its North American subsidiary Jeremias Inc. operating from Marietta, Georgia. The company designs and produces modular single-wall and double-wall flue systems, freestanding industrial chimney stacks, ventilation towers, flue gas ducts, industrial silencers, and accessories (dampers, exhaust fans), serving three end markets: residential heating (wood, gas, oil, biomass appliances), commercial hospitality (commercial kitchens, bakeries, laundromats, pizza ovens), and industrial buyers (breweries, marine/shipbuilding, data centers, hospitals, MRI facilities, power generation, process plants). Its core technical differentiator is an overlapping (male/female) joint design — the company states it is the only North American manufacturer with this feature across its entire round-product line — combined with a broad set of UL, ULC, DNV GL, and Lloyd's Register certifications that cover grease ducts, zero-clearance assemblies, high-pressure gas vents, and marine exhaust applications.

Jeremias generates revenue primarily through engineered-to-order hardware sales priced on a quote basis via a direct enterprise field-sales team supported by applications engineers, with US distribution augmented by three stocking partners in Georgia, Ohio, and Illinois. The company cites 100,000+ installations worldwide, 4,000+ completed industrial projects, a presence in 60 countries, 10+ production sites, and 7 manufacturing plants across 6 countries. In 2024, Jeremias expanded into adjacent HVAC and renewable-energy markets through the acquisition of Baetulenn and opened a new Marietta manufacturing facility to deepen North American self-sufficiency, while continuing to invest in specification-side tools (VentBOM, System Registration, Jeremias University training) to embed its products in engineer and contractor workflows. The company is privately held by the founding family and operates without external private equity or venture capital ownership.
