Elektro Rosler

What Elektro Rosler does

Elektro Rösler GmbH is a privately held German electrical-engineering services provider headquartered in Burghausen, Bavaria, operating since 1953 with approximately 250 employees across four offices in Germany (Burghausen headquarters, Berlin Süd) and Austria (Wels, Gilgenberg via the wholly owned Elektro Rösler Austria GmbH subsidiary). The company delivers a full-service portfolio organized across seven divisions: Gebäudetechnik (building technology including power supply, data/network, security, fire protection, building management, and medium voltage up to 30 kV), Industrietechnik (industrial technology covering measurement and control, automation, and EMR engineering with ATEX/SIL expertise), Analysentechnik (process analytics including gas chromatography and gas warning systems), Planung (engineering planning per HOAI using Siemens SIMARIS, EPLAN, COMOS, Revit, and other CAD/BIM platforms), Schaltanlagenbau (custom switchgear manufacturing up to 1,600 A), Wartung (maintenance contracts and 24/7 emergency service), and the Rösler Regenerativ sub-brand for renewable energy (photovoltaic, storage, heat pumps, Agri-PV, and ChargePoint e-charging infrastructure). Operations hold ISO 9001, ISO 14001, SCC (20+ years for petrochemistry), WHG, and DIN 14675 certifications, enabling service to regulated industries.

The company's revenue model is project-based, professional-services oriented, with three identifiable streams: (1) electrical installation services for industrial and commercial clients won through competitive bidding and direct engagement; (2) recurring maintenance and 24/7 emergency service contracts with established accounts in petrochemistry and logistics; and (3) hardware-attached renewable energy system sales under the Rösler Regenerativ sub-brand. Go-to-market is direct field sales via decentralized regional teams deployed at client sites, with no platform/digital-channel-led model and no public pricing.

Customer base is enterprise and industrial B2B, anchored by German Mittelstand and blue-chip industrial names including Wacker Chemie, OMV Deutschland, Segro, Hermes, HEAD, Berchtesgadener Land, Lambertz Solutions, Infraserv Höchst, Borealis AG, and Zeppelin GmbH, with a primary vertical emphasis on the chemical/petrochemical sector located in the Bavarian Chemical Triangle. Leadership comprises sole managing director Wolfgang Straubinger (since 2020), commercial director/CFO Walter Pötzinger, and functional heads for industrial technology, switchgear, planning, solar/Agri-PV, and Austria operations. The company has no external investors, no disclosed funding rounds, no M&A history, and no revenue disclosure in the input data; growth is internally funded and reinvested, with active emphasis on Austria expansion and the renewables product line.
