Hydreatio

What Hydreatio does

Hydreatio GmbH is a privately held German water technology company headquartered in Grünwald near Munich, organized as a group of three proprietary brands: Aqua Predict (AI-powered water diagnostics and predictive analytics), Rotreat (membrane-based water treatment, including the RCDT 3.0 high-recovery membrane modules), and Voigtlaender (zero-salt electrolysis disinfection systems producing Anolyte/hypochlorous acid). The company sells integrated water treatment, disinfection, and monitoring solutions to enterprise customers across food and beverage, pharmaceutical and healthcare, aviation, hospitality and buildings, agriculture, and industrial manufacturing, with deployments at Fraport (Frankfurt Airport), Macau International Airport, Danone, Merck, Fresenius, and Unilever among others.

The underlying technology stack combines advanced membrane filtration (MF/UF/NF/RO) with Voigtlaender's three-chamber zero-salt electrolysis and an IoT sensor layer that monitors pH, turbidity, temperature, microbial levels, and chemical concentrations in real time. Aqua Predict adds predictive analytics, anomaly detection, and automated dosing/filtration control on top of that sensor stream. The portfolio includes containerized and decentralized units for rapid or off-grid deployment, and systems are certified to UN/WHO, ISO 9001, EU CE, DVGW, ICAO, and TVO standards, supporting sales into regulated end-markets.

Hydreatio monetizes through a mix of project-based hardware sales (€25,000–€170,000 per system), professional services for installation and project execution, and recurring maintenance and monitoring contracts. The go-to-market is enterprise field sales with direct engagement, supplemented by a multi-brand distribution architecture (each brand has its own website and positioning) and content marketing via case studies, a blog, and social channels. The company is managed by Christoph Schwager and Nick Stübbe and is privately held with no disclosed external investors.
