Teething Technique

What Teething Technique does

Zahnen Technik GmbH is a privately held, family-run German engineering company founded in 1958 in Arzfeld (Eifel region) and operating today with 51-100 employees across its Arzfeld headquarters, an InnovationLab in Üttfeld, a Cologne business address, and acquired operations in Jüterbog and Rödermark. The company specializes in holistic "Water Engineering Performance" — the integrated delivery of water and wastewater treatment plants combining electrical engineering, mechanical engineering, process engineering, standardization and digitalization under one roof, typically acting as general contractor on municipal tenders.

Its core product platform comprises ISO by zahnen (also branded Wave Cloud), a digital engineering platform with an embedded "Water Engineer" AI assistant for planning, design, sales and quotation preparation through to the digital twin; Control Cloud by zahnen, an AI-supported 24/7 process-control and early-warning system with a Gewässermonitoring (water-level monitoring) module; Pure Water by zahnen / Pure Water by zahnenSE, a modular wastewater-treatment solution including the 4th purification stage for trace-substance removal piloted at the Speyer WWTP to address the EU KARL municipal wastewater directive; and the Flexbed Filter by zahnen, an innovative filter system for the 4th purification stage. The portfolio is completed by Service by zahnen (consulting, maintenance, retrofit, 24/7 emergency hotline) and the in-house InnovationLab for training and R&D.

Zahnen's business model combines one-time, project-based revenue from plant construction (Anlagenbau / Factory Engineering) with hardware sales of proprietary products, recurring revenue from annual service and maintenance contracts, professional services / consulting, and subscription-style revenue from Control Cloud monitoring. Customers are primarily German municipal water and wastewater utilities (Stadtwerke, Verbandsgemeinde, Entsorgungsbetriebe), public-sector climate-neutrality programs (e.g., Kleve, Speyer), cross-border utilities in Belgium and Luxembourg, and Smart Cities / flood-management authorities. Pricing is quote-based and tender-driven, with no public price list. The company executes go-to-market through direct enterprise field sales, an inside-sales tender-response team (Kalkulation), and co-marketing alliances with Siemens, FlowChief, Nivus, EPLAN, Sülzle Klein and Pyreg.

Core offering

Zahnen Technik GmbH designs, builds, automates and services water and wastewater treatment plants as a holistic general contractor, combining in-house electrical, mechanical and process engineering with proprietary digital products. Its portfolio includes the ISO by zahnen (Wave Cloud) engineering platform with AI "Water Engineer" assistant, the Control Cloud AI-supported 24/7 monitoring and early warning system, Pure Water by zahnenSE modular wastewater treatment with 4th purification stage, the Flexbed Filter, and recurring service and maintenance contracts including a 24/7 emergency hotline.

Product overview

Zahnen Technik offers a platform-plus-modules architecture built around the holistic "zahnen Water Engineering Performance" approach, combining factory engineering (Anlagenbau/Factory Engineering by zahnen) with a family of branded digital and physical products. The digital backbone is the ISO by zahnen engineering platform (also referred to as Wave Cloud), whose "Water Engineer" digital assistant standardises pre-planning, engineering, sales and quotation preparation through to the digital twin. Live plant operation is delivered through Control Cloud by zahnen, an AI-supported 24/7 process control and early warning system that incorporates the Gewässermonitoring (water monitoring) module for flood protection. On the physical/water-treatment side, the portfolio includes Pure Water by zahnen (modular wastewater treatment, with the Pure Water by zahnenSE variant delivering the 4th purification stage) and the Flexbed Filter by zahnen. These are complemented by Service by zahnen (consulting, maintenance, retrofit, 24/7 emergency service, automation, DGUV V3 inspection) and supported by the InnovationLab in Üttfeld for training and R&D. Together, these products allow Zahnen Technik to deliver end-to-end water and wastewater solutions — from digital engineering and AI-supported monitoring to modular treatment hardware and lifecycle service — under one roof.
