What Venturetec Rotating Systems does

Venturetec Rotating Systems GmbH is a German specialist manufacturer of slip rings (Schleifringe) and rotary unions (Drehübertrager), headquartered in Kaufbeuren, Bavaria, and operating as a wholly-owned subsidiary of Austrian industrial group Berndorf AG since 2017. The company was founded in 2008 by Kurt Dollhofer as Venturetec Mechatronics GmbH, acquired KGM in 2009, was taken over by Berndorf AG in stages between 2014 and 2017, and was rebranded to its current name in 2020 alongside a move to a new 1,400 m² facility. Its core technology is the design, engineering, and assembly of customer-specific rotating interfaces that transmit power, electrical signals, data (including fiber optic via FORJ), and media (gas/liquid) through a rotating joint, combining contacting (brush-type), capacitive (contactless), FORJ, and media feed-through technologies within a single integrated unit. Standardized multi-channel products range from 12-way pancake slip rings to 215-way high-capacity units used in industrial, defense, and medical applications.

Venturetec serves six primary end markets: medical technology (CT, PET-CT, 3D cardiac imaging with up to 6.25 Gbit/s data rates), defense (air defense radar, RCWS/CROWS, naval optoelectronic masts, flight simulators, high-G centrifuges, satellite communications, reconnaissance gimbals), surveillance (radar, HD-SDI cameras, FLIR gimbals, satcom terminals), propulsion (private yachts, cruise ships), industrial automation (food, machine tools, special machinery), and entertainment (theater stages, amusement rides, simulators). The go-to-market is sales-led and project-based: dedicated in-house sales staff (Thomas Einsle, Rainer Fasel) handle direct engagement from the Kaufbeuren HQ, a wholly-owned US subsidiary in Maryland covers North America, and five commercial agencies represent the company in France, Israel, Spain, Italy, and Sweden. Revenue is generated from custom one-off hardware sales, multi-year service contracts (diagnosis, repair, maintenance, spare parts across all slip ring brands), and modular upgrades that modernize installed units. Demand generation relies on defense trade fairs (DSEI, Eurosatory, IDEB, IDET) and industrial events (SPS Nuremberg) rather than e-commerce or marketplace channels.

The company holds ISO 9001:2015 certification (since 2018), implemented ISO 27001/NIS2 IT security processes in 2025, and qualified for the Cyber Trust Europe label in 2026, with manufacturing done exclusively in Germany. It employs approximately 60 people and is led by CEO Stephan Neubauer (since 2015). Disclosed end-customers include AMST (Austrian Maritime Systems Technologies) for human training centrifuges, German Navy programs (Fregatte Sachsen), space-debris laser detection programs, and pilot disorientation trainer integrators. The Berndorf AG group parent provides access to a network of 60+ companies across 20+ countries, supporting cross-border manufacturing and market reach.

Revenue model

1. Custom Slip Ring and Rotary Union Sales: Venturetec generates revenue through the design, development, and sale of customer-specific slip rings and rotary joints. Each product is tailored to the customer's application requirements, typically involving project-based sales with custom pricing. Revenue is primarily one-time hardware sale driven, with potential for follow-on spare parts, upgrades, and after-sales service.
2. After-Sales Service, Maintenance & Spare Parts: Ongoing revenue from after-sales support including diagnostics, repair, maintenance, and supply of wear and spare parts for slip rings regardless of original manufacturer. Service contracts and spare part supply generate recurring revenue from the installed base.
3. Upgrades and Modernization: Modular upgrade services that extend the capabilities of existing slip ring installations, enabling customers to meet new technical requirements without full replacement. This provides a cost-efficient revenue stream and strengthens customer retention.
