JUDO Wasseraufbereitung

What JUDO Wasseraufbereitung does

JUDO Wasseraufbereitung GmbH is a privately held German manufacturer of water treatment equipment and systems, founded in 1936 and headquartered in Winnenden, Germany. The company designs, produces, and distributes a broad portfolio spanning protective backwash sediment filters, ion-exchange water softeners (i-soft, SOFTwell), alternative lime protection systems (i-balance, Bio-balance, BIOSTAT), dosing pumps, leakage protection devices (ZEWA i-SAFE, HOME GUARD), reverse osmosis units (Bioquell-PURE), UV disinfection, heating protection systems (HEIFI, i-fill), and industrial systems including electrodeionization and pre-engineered green-hydrogen water treatment (CONTIPURE). It operates from seven German locations and serves international markets through country-specific websites and distributor networks in France, Italy, Spain, Canada, Austria, Switzerland, China, and Poland. The company is self-described as one of the largest manufacturers of water treatment systems in Germany and is a certified VDI partner (VDI 4704, 6023, 2047), with products certified to VDI 2035, VDI 3803, DIN EN 1717, DIN EN 285, and other German and European standards.

JUDO's business model is predominantly hardware sales of physical water treatment equipment, supplemented by professional services including VDI-certified training seminars, water analysis, and building services consulting, plus recurring sales of conditioning chemicals such as JUL mineral tablets and JKL scale stabilization products. The company employs a product-led go-to-market motion: a multilingual website with product finders, downloadable catalogs, CAD/BIM data, and user manuals drives demand to a professional installer network of plumbers, building services consultants, and engineers. International visibility is reinforced through trade show participation (Aquatech Amsterdam, Interclima Paris 2026, GET Nord 2026, INSTALACJE Poland) and a 'WunschWasser On Tour' roadshow. Customer segments span residential homeowners, professional installers, industrial and commercial operations (including hospitals, data centers, and printing facilities), and building developers requiring centralized multi-unit softening.

Revenue is not publicly disclosed. JUDO is owned and operated by authorized representatives Hartmut J. Dopslaff and Kathrin Reggi-Dopslaff, with no disclosed institutional investors, parent company, or external capital. The firm has invested in a connected-device platform via the JU-Control app, Amazon Alexa voice integration, a WLAN Connectivity Module, and a published smart-home API, while maintaining compliance with the German Supply Chain Due Diligence Act (LkSG) and WEEE electronic equipment disposal registration.
