The DRAG'EAU range · EF-i · DS-i
Two devices, one physical method, zero maintenance.
EF-i removes the harmful effects of limescale. DS-i completely removes sludge from closed circuits. Two physical devices, each machined from 316L stainless steel, warranted for a decade.
No consumables · No maintenance · No chemicals
Two lines
For each problem, a solution.
Limescale encrusts. Sludge corrodes. DRAG'EAU answers each one with a dedicated line · the same physics, two missions.
Limescale, neutralised for life.
It reshapes how limescale crystallises so it stops encrusting, and clears what's already there. Your minerals stay intact.
- From the home tap to industry
- No salt, no softeners
- Zero maintenance, forever
Circuits free of sludge and rust.
It puts sludge back into circulation, passivates the metal and halts corrosion in closed heating and cooling circuits.
- Closed circuits protected
- No purges, no consumables
- More thermal efficiency
The mechanism
See the water from inside.
No electronics. No chemicals. Just geometry, steel and water in motion. Scroll and travel through the device.
Scroll to travel through the device
Water enters and spins.
The internal geometry creates a vortex that multiplies the water's kinetic energy and dissolving power.
It narrows. It accelerates.
The Venturi effect speeds up the flow and sets the stainless-steel core vibrating at the heart of the device.
The waves are born.
Low-frequency, high-intensity vibrations break calcite into a fine powder that no longer encrusts.
Water comes out pure.
Limescale changes form, deposits dissolve and your minerals stay intact. For good.
Physics. Not chemistry.
And it all happens inside a single piece of steel, with nothing to maintain.
The steel
316L Stainless Steel
Every device is machined from a single piece of 316L stainless steel · the surgical, food-grade alloy demanded by the most exacting industries. Polished, sealed and proven to last for decades.
- 0L
- Stainless steel, solid body
- 0 bar
- Working pressure

- Years building the range
Patented technology, recognised worldwide. 99% of the device is 316L stainless steel; the rest, food-grade seals built to last.
Find your device
It is chosen by your flow rate or your pipe diameter.
Ten standard sizes, from a home's service connection to an industrial plant. Pick the model and check its technical specifications.
EF-i Anti-limescale

Select the nominal diameter
The size is determined by the installation's estimated flow rate or, failing that, by the pipe diameter.
Which product do I need?Sizes above the range shown can also be manufactured, as bespoke units made to order.
The proof
We don't promise it. We prove it.
Limescale crystals under the microscope, bench tests and thousands of installations. Physics is measurable.
