Schlentzek & Kühn GmbH

What Schlentzek & Kühn GmbH does

Schlentzek & Kühn GmbH is a Berlin-based, family-owned provider of certified fire protection (vorbeugender Brandschutz) and security technology solutions serving industry, commerce, and public-sector clients across Berlin-Brandenburg and Central Germany. Founded in 1995 by Frank Schlentzek and Christian Kühn, the company employs more than 40 staff and apprentices across headquarters in Berlin-Bohnsdorf and a branch in Teutschenthal opened in 2019 to extend coverage to Saxony-Anhalt, Thuringia, and Saxony.

The company's core offering is anlagentechnischer Brandschutz (plant-based fire protection), spanning Brandmeldeanlagen (BMA) for early fire detection, Sprachalarmanlagen (SAA) for voice evacuation, Rauch- und Wärmeabzugsanlagen (RWA) and Rauchschutz-Druckanlagen (RDA) for smoke and heat extraction, and Löschzentralen (SLZ) for extinguishing control. These systems are integrated via the Winguard manufacturer-independent hazard management platform supporting LON, KNX, IP, and Bacnet protocols for smart building interoperability. Adjacent security offerings include Einbruchmeldeanlagen (EMA), video surveillance, Hausmeldeanlagen, and natural ventilation systems. The company holds DIN 14675 certification across all phases, DIN EN 16763, VdS, ISO 9001, and is a founding member of the ZVEI Working Group of Installers and Planners, with active participation in DIN and DKE standards committees. Marquee reference clients include the German Federal Chancellery (Bundeskanzleramt), Vattenfall Europe AG, Allianz Treptowers, the Haus der Bundespressekonferenz, B.E.S. Brandenburger Elektrostahlwerke, and Berlin Brandenburg Airport Terminal 1.

Revenue is generated through three streams: project-based one-time installation revenue for new construction and modernization; recurring maintenance and service contracts including 24/7 emergency response; and managed remote services covering remote diagnostics, control, and dashboard-based monitoring of distributed RWA/RDA systems via the Kingspan STG-Beikirch RMS platform. Pricing is not publicly disclosed and is delivered through individualized, consultative project quotes. Go-to-market is direct enterprise field sales supported by referral-driven growth from existing marquee clients, complemented by content marketing, social media, the Sibra newsletter, and a free Brandrisiko-Check demand-generation tool. The firm operates as an owner-managed GmbH with no external investors, parent company, or public listing.
