What Kemper does

Kemper (Gebr. Kemper GmbH + Co. KG) is a privately held German industrial manufacturer headquartered in Olpe, operating three business divisions: Building Technology (Gebäudetechnik), Casting Technology (Gusstechnik), and Rolled Products (Walzprodukte). The Building Technology division is the strategic core, focused on drinking water hygiene, safety, and energy efficiency in buildings. Its product architecture rests on two complementary systems — the KHS Hygienesystem, which prevents stagnation and manages temperatures via the proprietary Venturi-Strömungsteiler flow divider, KHS CoolFlow cold-water circulation, and automated hygiene flushing, and the KTS ThermoSystem, which heats water on demand in flow-through fresh-water stations (S/M/L sizes with cascade capability up to 600 l/min). The PRO product layer adds digital intelligence — GLT (building management system) connectivity, Modbus RTU RS485, Kemper Cloud integration via the PRO WaterManager IoT gateway, automatic optimization suggestions, and predictive maintenance analytics. Supporting the systems are FROSTI frost-proof outdoor valves, MULTI-THERM PRO digital circulation control valves, TRESOR water-and-electricity supply stations, and a full portfolio of shut-off, safety, pressure-reduction, control, and measurement valves.

Casting Technology produces lead-free Rotguss (gunmetal) and multi-component bronze cast parts (REACH- and RoHS-compliant); Rolled Products manufactures pure copper, tin bronze, and proprietary KHP-series alloy strips (CuNiSi, CuNi3SiMg, CuSn0.15, CuCrZr, CuFeP). Dendrit STUDIO, a wholly-owned subsidiary acquired in January 2010, provides graphical CAD and hydraulic-calculation software used by 20,000+ sanitary/heating trade professionals and integrated with Kemper sizing tools.

Kemper serves healthcare facilities, hotels, multi-family and single-family residential buildings, public buildings, and industrial manufacturers, reaching end users through a trade-professional channel of installers (Installateure), plumbers (SHK-Fachhandwerk), and building technology planners (Fachplaner). The company generates revenue primarily through hardware sales across the three divisions, supplemented by professional-services revenue from an extensive seminar program (E-, Z-, W-, D-, K-, AT-series held in 15+ German cities) and licensing/royalty revenue from Dendrit STUDIO. Pricing is quote-based and project-specific rather than publicly listed. The company operates across eight European markets (Germany, Austria, Switzerland, UK, Netherlands/Belgium, Czech Republic, Denmark) via country-specific websites and subsidiaries, and holds an extensive stack of regulatory certifications — DVGW, UBA BWGL, WRAS, SVGW, VA, ÜA, DIN EN 1717, DIN 1988-200, REACH, RoHS — that constitute a significant barrier to entry in regulated European drinking-water installations.

Core offering

Kemper manufactures and sells valves and integrated systems for drinking water hygiene in buildings (the KHS Hygiene System and KTS ThermoSystem), shut-off/safety/control valves, frost-proof outdoor fittings, and supply stations. The company also produces lead-free Rotguss (gunmetal) castings and rolled copper and copper alloy strips as industrial input materials, and operates the Dendrit STUDIO planning software subsidiary.

Product overview

Kemper (Gebr. Kemper GmbH + Co. KG) is a German industrial manufacturer operating three business divisions: Gebäudetechnik (Building Technology), Gusstechnik (Casting Technology), and Walzprodukte (Rolled Products). The Gebäudetechnik division is the primary product portfolio, focused on drinking water hygiene — centered on two complementary systems: the KHS Hygienesystem and the KTS ThermoSystem. The KHS system prevents stagnation and manages cold water temperatures through the KHS Venturi-Strömungsteiler (flow divider — the system's core), KHS CoolFlow (active chilled water circulation), KHS Hygienespülungen (automated hygiene flushing), KHS Temperaturmessarmaturen (temperature measurement fittings), and KHS Systemsteuerungen (system controls). The KTS ThermoSystem handles drinking water heating via KTS Frischwasserstationen PRO (sizes S/M/L for different building types, with digital intelligence, GLT connectivity, and cloud integration) and KTS ThermoTank S (buffer storage), supported by the PRO WaterManager IoT gateway and online KTS Auslegungstool (sizing tool). Additional Gebäudetechnik products include FROSTI frost-proof outdoor valves, MULTI-THERM PRO digital circulation control valves, TRESOR supply stations (water and electricity), and full ranges of shut-off, safety, pressure reduction, control, and measurement valves. Digital planning is supported by Dendrit STUDIO (graphical CAD/calculation software, a Kemper subsidiary). The Gusstechnik division produces lead-free Rotguss (gunmetal) cast parts — both raw and machined — in various bronze grades (bleifrei and Mehrstoffbronze). The Walzprodukte division manufactures rolled copper and copper alloy strips across pure coppers, tin bronzes, and the proprietary KHP alloy series.
