Hydro-Elektrik AS

What Hydro-Elektrik AS does

Hydro-Elektrik AS, operating under the HydroGroup brand, is a private engineering contractor that designs, manufactures, and delivers water treatment, water storage, and process automation systems. Founded in 2004 and headquartered in Bergen, Norway, the group operates through a multi-entity structure spanning Norway (Hydro-Elektrik AS in Nyborg) and Germany (Hydro-Elektrik GmbH in Ravensburg as the operational headquarters, plus RWT GmbH in Gütersloh focused on industrial process water and Küchle GmbH in Tannheim). The company's core technology stack centers on ozone-based oxidation, membrane filtration, and ion exchange processes, anchored by two proprietary assets: the HYDROZON® ozone-bromine process (certified under DIN 19643-5 for chlorine-free swimming pool water treatment) and the patented HG-MFO membrane filtration method with ozone regeneration. The product portfolio spans compact drinking water treatment plants (TWK), swimming pool filter systems (TecBox P30, H30-L, H30-XL), plasma-based ozone generators (POX), industrial softening and reverse osmosis systems, multiple degassing modalities (thermal, vacuum, membrane, chemical), and Hydroxymat oxygen generators.

HydroGroup sells custom-engineered, project-based solutions rather than off-the-shelf products, generating revenue through three streams: one-time equipment sales, system solutions and engineering services, and ongoing service and maintenance (including remote support via TeamViewer). The go-to-market combines direct enterprise field sales targeting municipalities, industrial facilities, and power plants with a certified Premium Partner Network for swimming pool technology distribution. Customer segments are organized vertically — municipal water supply, industrial and power plants, swimming pools and wellness (primary), and trade and commerce (secondary) — with pricing conducted on a project-specific, quote-based basis. The company maintains a modest marketing footprint across LinkedIn, Facebook, YouTube, and Instagram, supplemented by technical content and newsletters on its website. Notable recent signals include the May 2025 commissioning of the Steinatal waterworks (a third surface-water treatment plant in the Harz region) and the Standortoskar 2025 award received by Hydro-Elektrik GmbH for innovation and unique business model. No public listing, external institutional investment, or disclosed revenue figures are present in the source material.
