Klotter Elektrotechnik

What Klotter Elektrotechnik does

Klotter Elektrotechnik GmbH is a German specialized electrical engineering company headquartered in Rheinau-Freistett, Germany, founded in 1997 by Werner Klotter and Roswitha Wiegert-Klotter. The company designs, builds, and services transformer stations, switchgear and distribution systems (up to 5000A), industrial automation and control technology, and complete electrical building infrastructure for industrial and commercial construction. It serves customers across at least nine verticals including pharmaceutical, automotive, paper, healthcare, data centers, energy providers, and various manufacturing sub-sectors (sawmills, gravel plants, hydroelectric, aircraft construction), operating as general contractor for end-to-end electrical energy supply projects.

Its technical capabilities rest on proprietary engineering calculations — cross-manufacturer selectivity analysis, Pigler-standard pressure load calculations, and heat requirement calculations — combined with EPlan P8 for control cabinet planning and an in-house workshop certified to DIN EN standards. Components are sourced from premier manufacturers (ABB, Eaton, Schneider Electric, Siemens, Rittal, Hager, Sedotec), enabling flexible best-fit configurations. The company employs approximately 80 staff and provides 24/7 emergency service 365 days per year.

Since 2021, Klotter has operated as the anchor entity of E.GRUPPE GmbH, a Gimv-backed private equity platform that has consolidated six specialist electrical engineering firms. Revenue is generated through custom project-based B2B contracts (no standard pricing tiers) supplemented by recurring service and maintenance revenue, sold via direct enterprise field sales targeting industrial companies, energy providers, and infrastructure operators across Germany.

Core offering

Klotter Elektrotechnik GmbH plans, constructs, and maintains electrical infrastructure for industrial, energy, healthcare, and data center customers in Germany. Core offerings include custom transformer stations, switchgear and distribution boards (up to 5000A), industrial automation and control systems, complete building electrical technology, and 24/7 service and maintenance. The company also operates its own workshop for control cabinet and distribution manufacturing per DIN EN standards.

Product overview

Klotter Elektrotechnik, a member of E.GRUPPE, operates as an electrical engineering company offering comprehensive solutions across five core areas: transformer station construction, switchgear and distribution board manufacturing, control technology and automation, building technology, and service/maintenance. The company functions as a single integrated offering rather than a platform with modules—each service area operates as a distinct practice area that customers engage based on their electrical engineering needs. Products include Trafostationen for custom transformer station planning and construction, Schaltanlagen und Verteiler for standards-compliant switchgear up to 5000A, Steuerungstechnik und Automatisierung for production plant optimization, Gebäudetechnik for complete electrical supply in industrial/commercial construction, and Service und Wartung providing 24/7 emergency service and regulatory testing (DGUV V3).
