What Aquabion does

Aquabion (legally NFD sàrl, headquartered in Dudelange, Luxembourg) manufactures and distributes a single product line of ecological anti-limestone water treatment devices based on patented galvanic technology. The system uses a sacrificial zinc anode housed in a brass body, exploiting the natural galvanic effect to release zinc ions that act as nucleation agents, transforming hard, incrusting calcite into soft, non-adherent aragonite that flushes through plumbing without accumulation. Proprietary turbulence chambers (covered by patent N° 1636139) generate swirling flows that maximize water-anode contact and keep the unit self-cleaning, with no electricity, chemicals, salt, or consumables required across the product's lifespan. The technology is validated by independent studies from Singapore Polytechnic, the IWW Water Institute, Maribor University, and Lanxess, and holds DVGW, ACS-FR, WRAS, and OFI certifications.

The company operates a direct, sales-led go-to-market targeting two customer segments: Particuliers (individual residential homeowners) and Professionnels (plumbers, building managers, hotels, and small industrial users) across France, Belgium, and Luxembourg. Each market has a dedicated phone line and local sales presence, with leads generated through the company website (aquabion-distribution.com), verified third-party reviews, video testimonials, and a strategic partnership with Les Compagnons du Devoir that integrates Aquabion into French artisan training. Revenue is generated primarily through one-time hardware sales (models AB-D20, AB-S15, S20, and the AcoMillions professional device) plus associated installation services, with quote-based pricing, a 5-year product warranty, and a 1-year money-back guarantee. Payment terms include 30-day invoicing, prepayment on first orders, and a 50% deposit on custom orders above €3,000.

Aquabion reports over 500,000 cumulative installations since 1992, a 95%+ customer satisfaction rate, and a 4.8/5 verified-review score. The company positions its offering as approximately 70% cheaper over an 8-year horizon than traditional salt-based water softeners, supported by an average observed total cost of ~€3,000 per single-family home. The business is privately held by NFD sàrl under Luxembourg law, with no disclosed outside funding, parent company, or institutional ownership, and is operated by M. C. Gerhardt as the named representative of the legal entity.
