What KÖHL does

Köhl GmbH is a German building technology specialist founded in 1971 and headquartered in Trier, with an operational branch in Ingelheim am Rhein. The company delivers four interconnected service pillars: (1) Gebäudetechnik — electrical installations, energy distribution, medium- and low-voltage switchgear up to 6300A, transformers, KNX-based smart building control, and the proprietary ARCON arc fault protection system that extinguishes arc faults within ≤2 ms; (2) Gebäudeautomation — measurement, control and regulation technology (MSR) plus process and control engineering for centralized building management, SPS systems, and high-availability remote monitoring; (3) Sicherheits- & Netzwerktechnik — fire alarm systems (Detectomat, Esser/Honeywell, NSC, Luuta, Securiton), hold-open systems (Hekatron), intrusion detection, AI-supported video surveillance (Vimacc, Accellence), electronic access control (SimonsVoss, DOM, Schraner), and structured network infrastructure; and (4) Services — technical building management, CAD-supported project planning, maintenance and repair, electrical safety inspections, and energy controlling. Köhl holds DIN EN ISO 9001:2015 certification across both locations and DIN 14675 certification for fire alarm systems.

The company serves industrial, commercial, public-sector, and office-building clients in the Rhineland-Palatinate region via direct B2B field sales with project-based technical consultation, project planning, execution, and ongoing after-sales maintenance. Revenue is generated through one-time project implementation (electrical installation, switchgear, security system deployment) supplemented by recurring revenue from maintenance contracts and managed technical building management services. The company has been part of HPM DIE HANDWERKSGRUPPE since 2019, a family-owned business group founded in 1989 with 160+ craft businesses across Germany and Austria, providing shared administrative services, compliance, and cross-company networking while Köhl retains operational independence. Headcount stands at over 80 qualified specialists. Marketing is primarily B2B-driven through the corporate website, job portals for recruitment, and the HPM group ecosystem, with no disclosed channel partners or distributors.
