Schrupp Elektroanlagen Kaiserau GmbH

What Schrupp Elektroanlagen Kaiserau GmbH does

Schrupp Elektroanlagen Kaiserau GmbH is a family-owned German electrical engineering services provider headquartered in Marienheide (Bergisches Land), operating since its founding by Helmut Schrupp in May 1967 and reorganized as a GmbH on January 1, 2009. The current owner, Jürgen Schrupp (Dipl.-Ing.), leads the firm alongside managing directors Moritz Schrupp and Lars Sündtgen, with more than 60 electrical professionals in full-time, part-time, and apprenticeship roles. Its core offering spans electrical installation (Elektroinstallation), control system construction (Steuerungsbau) with a specialization in crane controls, PLC programming on Siemens S5/S7 and Allen Bradley platforms, rapid-response industrial assembly (Industriemontagen) deployed globally, custom cable assembly (Kabelkonfektion), lighting technology planning using Relux Professional 2007, E-Check safety inspections, building technology including EIB/KNX and security systems, and in-house metalworking (Schlosserarbeiten) covering turning, milling, grinding, and TIG/MIG welding.

The business operates on a project-based professional services and hardware sales model. Pricing is quote-based for installation and assembly contracts, with a small retail line (e.g., the Geniale Feuertonne fire drum at €17.85 including VAT per unit) for walk-in material purchases at the Leppestraße 191 headquarters. The go-to-market combines enterprise field sales — deploying service teams and apprentices directly to customer sites — with a direct-to-consumer storefront for material sales from warehouse stock. Two primary customer segments are addressed: industrial and commercial enterprises requiring electrical infrastructure, control systems, and rapid-response assembly, and private customers seeking residential installation, building technology, and safety inspections. Revenue streams are diversified across installation services, control system manufacturing (terminal boxes, contactor controls, flexible PLC controls), industrial assembly, material sales, and custom cable assembly.

The company's disclosed commercial anchor is a decade-plus supplier relationship with one of the largest European crane manufacturers for control systems, alongside unnamed automotive manufacturers served through industrial assembly projects. Geographic reach spans Germany, Europe, and worldwide. Distribution relies exclusively on direct channels — field teams for enterprise delivery and on-site retail for material sales — with the corporate website (sek-web.de) functioning as the primary marketing surface. The firm is privately held with no external investors, no subsidiaries, and no public funding history, indicating a self-financed Mittelstand operating model.
