Answers to you questions

Which sectors benefit most from our water treatment solutions?

We support officeshotels and restaurantsyachts, private residences, schools, and industrial facilities. Each environment comes with its own constraints—comfort, sanitary safety, or technical performance—so we tailor our solutions to every situation.

What is the difference between ultrafiltration and reverse osmosis?

Ultrafiltration removes visible particles and some bacteria, but allows nitrates, viruses, endocrine disruptors, and pharmaceutical residues to pass through. Reverse osmosis, on the other hand, removes up to 99.9% of contaminants, including the most microscopic ones.

Which standards guarantee the quality of our installations?

We use only ACS-certified equipment compliant with ISO 9001 (quality) and ISO 14001 (environmental) standards. In medical or food-service environments, we also apply anti-legionella disinfection protocols.

Do you offer solutions adapted to yachts and boats?


Yes. We specialize in marine reverse osmosis systems. Our dual-membrane kits treat dock water or desalinate seawater, ensuring safe drinking water—even after stagnation in tanks. We have been selected by renowned shipyards such as Aventura, Fountaine PajotLagoonExcess, Nautitech, Dufour, and Beneteau to equip their 12–20 m monohulls and multihulls.

How do I choose between purchase and rental?

Purchasing is ideal for long-term autonomy. Rental suits organizations seeking a fully inclusive service: installation, maintenance, filters, and interventions included in a predictable monthly plan with no surprises.

Is filtered water really more environmentally friendly?


Yes. By eliminating plastic bottles, you reduce waste and transportation. Our water dispensers and reverse osmosis systems consume very little energy while providing unlimited access to high-quality water—without unnecessary carbon impact.

Can I connect a reverse osmosis system to a dispenser or a design tap?

Absolutely. The OneZero reverse osmosis system integrates seamlessly with our U4/U5 taps or the Oceane water dispenser. You get chilled, hot, or sparkling water from a single point—without compromising on design or performance.

What water options are available with your dispensers?

Our mains-connected dispensers provide chilled, ambient, hot, and sparkling water. In corporate or hospitality environments, they adapt to all uses: everyday hydration, beverage preparation, or eco-responsible customer service.
