Dr. Küke GmbH

Dr. Küke GmbH, headquartered in Wedemark, Germany, is a specialized biocide manufacturer and the self-described source for chlorine dioxide, covering the entire chlorine dioxide value chain from sodium chlorite feedstock through generation systems to finished solutions. The company holds ISO 9001 certification and operates its own in-house research department with close academic ties, converting scientific developments into market-ready products. Their core product line is the DK-DOX® system, a family of high-performance chlorine dioxide generation systems that have been in operation for over ten years, based on patented technology. Dr. Küke offers multiple chlorine dioxide production pathways — including 1-component and 2-component in-situ generation systems and ready-to-use ex-situ solutions — alongside sodium chlorite solutions packaged to DIN EN 938 standards. The company also produces QUANTOFIX® Chlorine Dioxide 3000 DK test strips (manufactured by Macherey-Nagel) for monitoring chlorine dioxide concentrations. Application areas include drinking water disinfection, hygiene in veterinary settings, food and feed industry sanitation, slime control, and protective treatment of liquids. Dr. Küke provides private-label manufacturing services, allowing customers to market DK-DOX®-based products under their own brands, and offers commissioning, remote access, telephone support, and annual maintenance for their generation systems.
