How does MEDIAGON, the salt-free limescale solution, work?
MEDIAGON addresses limescale build-up without removing calcium and magnesium from the water and without the operating constraints of a salt softener.

Water passes through the active zone
MEDIAGON relies on a static physical action around the pipe as water flows through it.
No injection · no electricity03
Crystallisation is directed differently
The technology is designed to influence nucleation and crystallisation of carbonates present in the water.
Minerals remain in the water04
Hard, adherent deposits no longer form
Directed crystallisation changes the behaviour of carbonates in the water. They remain in a non-adherent form, preventing lasting build-up on pipes and equipment.
Surfaces protected over timeThe competitive advantage
Two very different ways of managing limescale
A softener changes water hardness and requires recurring operating logistics. MEDIAGON acts on scaling with much simpler operation.

Inside MEDIAGON: the physical mechanism
How MEDIAGON works
MEDIAGON is fitted around the pipe: water continues to flow through the existing pipe without passing through an added in-line device.
Its principle is based on specific alloys and static fields, with the aim of promoting mineral crystallisation within the water rather than adherent deposits on surfaces.
Calcium and magnesium remain in the water. MEDIAGON targets scaling; it is not designed to reduce water hardness.
The patented alloy: the passive generator
The system requires no electrical connection.
Its technological core uses a precision alloy of aluminium, copper and silicon. During manufacturing, heat treatment and molecular pressing permanently fix polarised micro-domains.
The housing therefore acts as a continuous emitter of multipolar static fields, using only its own surface potential.
Dielectric induction: contact-free action
The device is fitted directly around the incoming water pipe, without cutting the pipework or altering the plumbing.
Static field lines pass through the pipe wall by induction. Millimetre adjustment of the two half-shells eliminates air gaps and ensures optimal energy transfer to the moving fluid.
Whether the pipe is copper, steel, stainless steel or a polymer material such as multilayer pipe or PEX.
Homogeneous nucleation: the active field
In conventional hard water, calcium and carbonate ions are isolated by a thin protective water layer and can precipitate rapidly under thermal shock to form adherent calcite.
As the water passes through the device's static field, this barrier is subjected to an electrostatic force that weakens it.
Once released, the ions combine directly within the water flow, without contacting the pipe walls.
Transformation: from calcite to aragonite
Forced to combine in a moving flow under kinetic disturbance, the atoms do not have time to form compact calcite. They stabilise in a metastable state: aragonite.
This crystalline structure appears as friable microscopic needles.
Unable to agglomerate, this microscopic powder remains suspended and leaves naturally with the water. Plate heat exchanger performance is therefore preserved.
Curative effect: passive disaggregation
The treatment also has a curative action on installations that are already scaled.
First, the gentle mechanical erosion of aragonite micro-needles helps sweep existing scale.
Second, the altered crystalline balance of the water flow weakens old calcite. It loses adhesion, cracks and is progressively removed without releasing CO₂ microbubbles (pH unchanged).

Understand what MEDIAGON changes — and what it is not designed to change
MEDIAGON is not a salt softener. Its role is to change limescale behaviour to protect the installation while keeping naturally occurring minerals in the water.
Calcium and magnesium remain present. If the objective is softened water, that is a different treatment requirement.
MEDIAGON agit sur l’entartrage, pas sur la dureté mesurée.Minerals remain in the water, so a white trace may still appear on a surface after drying.
La différence recherchée est un résidu non adhérent, plus facile à éliminer.Pipe diameter, material, temperature, flow rate and use determine the correct model and installation position.

Frequently asked questions about MEDIAGON
Does MEDIAGON remove calcium and magnesium?
No. The minerals remain in the water. MEDIAGON targets scaling; it does not produce softened water.
Does MEDIAGON reduce water hardness?
No. Hardness is not reduced as it is with an ion-exchange softener.
Does the pipe need to be cut to install MEDIAGON?
The device is installed around the pipe. Feasibility and the appropriate model are checked according to pipe diameter and configuration.
Does MEDIAGON require salt, refills or electricity?
MEDIAGON operates without salt, without consumable refills and without an electrical supply.
What is the difference from a salt softener?
A softener reduces hardness by ion exchange. MEDIAGON keeps the minerals in the water and acts on their crystallisation to prevent lasting adhesion to surfaces.
