What DRAG'EAU does

DRAG'EAU (legally Drag'eau SARL) is a French private limited company founded in 2011 by Giovanni Drago and headquartered in Ensisheim, Alsace. The company designs, manufactures, and distributes physical water treatment devices for two principal applications: prevention and removal of limescale in sanitary installations (Anticalcaire EFi series, previously Eficalk) and autonomous desludging of heating and cooling networks (Désemboueur DSi series, previously Efibou). Both product families are built in 316L stainless steel and rely on a patented combination of vortex effect, Venturi-accelerated flow, and low-frequency sound waves generated by integrated ceramic elements, with no chemicals, consumables, or maintenance required.

The company serves three horizontal segments: residential homeowners (individual property owners), collective/tertiary buildings (maintenance providers, social housing operators, property managers), and industrial facilities with process-water and cooling-loop requirements. Distribution is executed through an independent distributor network across France, international distributors in 24 countries (with Italy via MY ACQUA Srl and a stated priority focus on Germany and Austria), and an internal sales team for key accounts and specification-driven project sales. The company transitioned from pure distribution to in-house manufacturing in 2019, holds multiple international certifications (ACS, TÜV, DVGW, NSF, OFI, QAI), and offers a 10-year product warranty. DRAG'EAU remains family-owned, operated by Giovanni Drago and his daughter Pamela Imbach-Drago (co-gérante) alongside partner-associates leading French, German, and Austrian operations, and reports over 100,000 customers worldwide without disclosing revenue.

Revenue model

1. Water Treatment Device Sales: DRAG'EAU generates revenue through the sale of physical water treatment devices (antiscale and desludger systems) sold directly to customers and through a network of distributors. Products are available in various sizes (from EF-i15/DS-i20 to EF-i200/DS-i200) for different applications. The company transitioned from distributor to manufacturer in 2019.
2. Distribution of Third-Party Products: Initially, the company started as a distributor of English and then German products for water treatment before developing its own patented products.

Core offering

DRAG'EAU designs, manufactures, and sells physical water treatment devices that prevent limescale buildup and remove sludge from heating, cooling, and sanitary water networks. The product portfolio centers on two stainless-steel (316L) lines: the Anticalcaire (EFi series) for antiscale protection of sanitary installations and the Désemboueur (DS-i series) for autonomous desludging of closed heating and cooling networks. The technology uses a combination of Vortex Effect, Venturi effect, and low-frequency sound waves generated by integrated ceramic components, and is sold via a quote-based model through French and international distributors plus direct key-account sales, with a 10-year warranty.

Product overview

DRAG'EAU offers two core product lines for physical, ecological water treatment: the Anticalcaire (EFi series) for limescale prevention and removal, and the Désemboueur (DS-i series) for sludge removal in heating and cooling systems. Both product families employ proprietary technology combining Vortex Effect, Venturi effect, and low-frequency sound waves generated by ceramic components, all housed in 316L stainless steel. The products require no consumables, no maintenance, and have no impact on water quality. They are offered in various sizes (indicated by model numbers from 15 to 200) to accommodate residential, collective/tertiary, and industrial installations. All products carry a 10-year warranty (2 years legal plus 8 years extended upon registration).

• DSi (Désemboueur): Self-sufficient desludging device for heating and cooling networks using Vortex Effect and Sound Wave technology. Product range includes DSi20, DSi25, DSi32, DSi40, DSi50, DSi50b, DSi65, DSi80, DSi100, DSi150, DSi200 models.
• EFi (Anticalcaire)

Products and services

• Anticalcaire EFi Series (EFi15 to EFi200) Physical antiscale device for sanitary installations that treats limescale in water pipes using Vortex Effect, Venturi effect, and low-frequency sound waves to dissolve existing scale and prevent new deposits through micro-crystallization. Available in 12 sizes (EFi15 to EFi200) for residential, collective, and industrial applications, and built in 316L stainless steel.
• Désemboueur DS-i Series (DS-i20 to DS-i200) Physical desludger device for autonomous cleaning of heating and cooling networks that neutralizes corrosion and removes sludge using Vortex Effect and low-frequency sound waves, with bacteriostatic action that prevents bacterial proliferation and forms a protective passivation layer on pipe walls. Available in 10 sizes (DS-i20 to DS-i200), built in 316L stainless steel.

Direct peers

• Scalewatcher: Manufacturer of electronic/induction-based limescale treatment devices installed on heating, cooling, and process water systems. Competes with DRAG'EAU on chemical-free, no-maintenance antiscale positioning across residential and industrial users.
• ClearWave (WaterMax / Clear Water Technology): US-based vendor of salt-free electronic water conditioning and scale-prevention devices marketed at residential and light commercial applications. Comparable to DRAG'EAU on the 'no chemicals, no maintenance' antiscale product proposition.
• Hydroflow UK: Provider of Hydropath/Hydroflow physical water conditioners marketed for limescale prevention in heating and cooling networks. Overlaps directly with DRAG'EAU on physical antiscale mechanisms and the same multi-segment customer base (residential to industrial).
• Christiani Wassertechnik (Vulcan): German manufacturer of Vulcan electronic water treatment systems for scale and rust, installed in residential and commercial heating/cooling pipes. Highly comparable to DRAG'EAU on physical water treatment technology and on its core German-speaking market focus.
• Hydropath Technology: UK-based pioneer of physical/electronic water treatment (Hydroflow/Hydropath units) targeting limescale and biofilm in heating, cooling, and plumbing systems. Closest direct competitor to DRAG'EAU on vortex/sound-wave antiscale technology and identical target customers (residential, commercial, industrial).

Broad incumbents

• Pentair: Large global water treatment and flow solutions company with industrial, commercial, and residential offerings including filtration, softening and scale-prevention equipment. Competes with DRAG'EAU in industrial and commercial water treatment via a broader, mostly chemistry- and membrane-based product portfolio.
• BWT (Best Water Technology): European leader in water treatment technologies including softening, filtration and antiscale solutions, with strong distribution in DACH and across Europe. Overlaps directly with DRAG'EAU in physical/chemical antiscale for residential, hospitality, and industrial clients in the same European geographies.
• Watts Water Technologies: US/EU-listed manufacturer of water treatment, plumbing, and heating equipment serving residential, commercial and industrial markets. Comparable to DRAG'EAU on the heating/plumbing installation and water quality value chain, but operating as a broad incumbent with multiple product families beyond scale control.
• Culligan International: Global incumbent in water treatment and conditioning including antiscale, softening, and filtration products for residential, commercial and industrial customers. Overlaps with DRAG'EAU in residential antiscale and broader water quality, but via a much broader portfolio including chemical and salt-based solutions.

Regional players

• Caleffi International: Italian manufacturer of components and water treatment devices for hydronic and sanitary systems, with deep presence in Italy and broader EU markets. Comparable to DRAG'EAU on the heating/sanitary-network plumbing channel, though it is primarily an Italian-rooted supplier rather than a pan-European brand.
