What DeWiTec does

DeWiTec GmbH is a Dortmund, Germany-based manufacturer of aviation lighting and safety equipment, founded in 2002 as a privately held GmbH with no external equity investors. The company operates from a headquarters located at Flugplatz (airfield) 7-9, Dortmund, and is managed by Geschäftsführer (Managing Directors) Peter Dettweiler and Maximilian Dettweiler, suggesting a family-operated Mittelstand business. Its product portfolio is organized into three divisions: Hindernisbefeuerung (obstruction lighting for towers, wind turbines, and cranes), Heliportausrüstung (heliport lighting and equipment for hospital and air rescue bases), and Flughafenausrüstung/Airport Technology (runway, taxiway, signage, and beacon systems for airfields). Supporting offerings include the proprietary DALMAS mobile photometric airfield lighting analysis system, the Cryonom cryogenic cleaning system for inset lights, constant current regulators, and GPS-synchronized controlled/monitored systems. All products are certified to ICAO Annex 14, FAA, CE, and German BMVBS standards.

DeWiTec's customer base is concentrated in Germany and selected European markets (Austria, Switzerland), serving two primary verticals: hospital heliports and medical air rescue operations (e.g., University Hospital Aachen, Cologne-Merheim, Heidelberg, ADAC Christophorus bases) and commercial/regional airports (Frankfurt, Hamburg, Cologne/Bonn, Düsseldorf, Nuremberg, Airport Niederrhein), with a secondary vertical in infrastructure obstruction lighting for wind farms and telecom towers. The company operates a direct sales model with no third-party distribution partners, leveraging a quote-based inquiry system, direct phone/email channels, and trade show presence at InterAirport (2023) and Light & Building (2022).

Revenue is generated through hardware sales complemented by professional services including project planning, installation, maintenance, photometric analysis, winter service, and training. Pricing is not publicly disclosed and varies by product configuration (voltage options, GPS modules, twilight switches, mounting accessories). The company has no disclosed funding rounds, no parent company, and no M&A activity in the source material, indicating organic growth funded internally.
