What Knill Gruppe does

Knill Gruppe is a privately held Austrian industrial group founded in 1712 and now in its 12th generation of family ownership, headquartered in Weiz, Austria. The group operates two legally independent divisions: Knill Energy Holding GmbH, which provides infrastructure products for power transmission and distribution (overhead line fittings up to 1,200 kV, vibration damping systems, high-voltage substation components, and polyester/aluminum cabinet systems), and Rosendahl Nextrom GmbH, which produces specialized manufacturing machinery for battery, cable, wire, and optical fiber production. Following the 2026 acquisitions of TBS Engineering and the Windak Group, Rosendahl Nextrom claims global market leadership in battery manufacturing solutions, while Nextrom is described as the world leader in optical fiber production systems. The Energy division serves utility grid operators and railway/tram operators through brands including Mosdorfer, Damp, Lorünser, Elsta Mosdorfer, EBG electro, Almatec, and Mosdorfer Rail.

The group's revenue model is anchored in B2B hardware sales of engineered components and capital equipment, supplemented by aftermarket services, commissioning, and maintenance. GTM motion is decentralized enterprise field sales: each of the 12 retained sub-brands maintains its own sales directors and managing directors, supported by 38+ localized subsidiaries across 19 countries. Pricing is not publicly disclosed and operates via enterprise contracts. Customers include energy utilities, railway and tram operators, battery manufacturers, cable and wire producers, fiber optic manufacturers, telecom operators, and industrial manufacturers. Notable proprietary technologies include the patented Tensorex C+ spring tensioning system, ROEX extruder series, RIO modular line control system, BMR 15X TT (world's fastest single-pocket battery machine), RoCOS X1, and fiber draw tower systems.

In 2026, Knill Gruppe has executed an aggressive acquisition-led growth strategy, adding TBS Engineering (battery equipment, from Marmon Group) and the Windak Group (cable packaging automation) to Rosendahl Nextrom, and acquiring a one-third stake in Pankl Racing Systems AG as a strategic diversification into high-performance automotive and aviation components. Group revenue is disclosed at €603 million across 3,000 employees globally. The company is entirely family-controlled by Christian and Georg Knill, with no external institutional investors or public market listing.

Direct peers

• Sovema Group: Italian supplier of battery production equipment and automated lines for lead-acid and lithium-ion cells. Direct competitor to BM-Rosendahl in the same battery-making equipment niche.
• Manz AG: Germany-listed supplier of automation, assembly and production equipment for lithium-ion batteries, electronics and solar. Overlaps with Rosendahl Nextrom's battery machinery business and with parts of its cable/capacitor automation footprint.
• PFISTERER Group: German-headquartered manufacturer of fittings, insulators and substation components for power transmission and railway catenary systems. Direct overlap with Mosdorfer overhead line fittings and Lorünser substation hardware; Knill notably acquired PFISTERER's rail division in 2022 to form Mosdorfer Rail.
• Maillefer (Nexans): Finland-headquartered manufacturer of cable production equipment, including extrusion, drawing and compounding lines for power, telecom and fiber optic cables. The closest direct competitor to Rosendahl in cable and wire manufacturing machinery.
• Ensto Oy: Finnish manufacturer of overhead line hardware, cable accessories and enclosures for power distribution. Comparable to Mosdorfer fittings and Elsta Mosdorfer/EBG cabinet systems across Northern and Central Europe.
• Preformed Line Products (PLP): US-headquartered specialist in overhead conductor hardware, spacers, dampers and cable accessories for transmission, distribution and rail electrification. Closely comparable to Mosdorfer and Damp within the energy division.
