How Digital Water Conditioning Works

The Calmat and Vulcan systems are physical water treatment systems that use mechanics to alter the way hardness scale forms in your water. The device will not soften the water as it doesn’t remove the dissolved minerals. It does however, alter the actual characteristics of the scale crystals so that the particles lose their ability to adhere to pipes, etc. The unit is placed on the outside of the pipe and need not come into direct contact with the water.

How Digital Water Conditioning Works: Electrical Impulses


The water is treated by electric impulses created by the electronic unit and passed into the pipe through the coils provided which are wrapped around the pipe. The coils work in pairs to form a frequency field to affect the crystals in the water flowing through the field.

Problems Caused By Scale


Scale causes many problems:

  • Piping becomes clogged
  • Surfaces lose their sheen and machinery malfunctions
  • Heating and energy costs rise
  • Cleaning expenses are high
  • the first sign of corrosion appear in the pipes in the form of rust
  • Pipes that carry drinking water experience an increase in bacterial growth

How Does Digital Water Conditioning Work To Solve All These Problems?

1. Vulcan Prevents Scale From Building Up In Pipes And Appliances

Water that has not been treated by the system, the scale particles join together to create sticky crystals that create solid deposits. The patented Impulse Technology changes the crystallisation of calcium and magnesium by using the natural process of electrophoresis. The crystalline structure changes into one that is smoother and rod-shaped and unable to adhere to one another. There is no new scale build-up. The more the crystalline structure is changed, the better the effect in terms of prevention of build-up.

It is vital that the mono-crystals formed by the impulse variation are allowed to grow as long as possible before their journey through the pipes begins. Larger crystals mean more time is needed for the crystals to dissolve and “die”. When the water is warm, the growth of the crystals is enhanced and they are therefore stronger and able to survive longer. This is why the longest lasting Vulcan effects (up to seven days) occur in warm water and why cold water shortens the Vulcan-effect (about two days).

2. Vulcan Is A Gentle Way To Disinfect Your Pipes

There are two processes that take place simultaneously in untreated, hard water:

a. The initial process is the build-up of scale deposits as a result of calcium crystals that fix themselves first to one another and then onto surfaces. The end result of this process is that carbonic acid (H2CO3) is produced as a side effect.

b. As part of the other process, the carbonic acid, at the same time, begins breaking down any existing built-up scale. This is what is known as the “natural resolving process”. Build-up is much faster than the natural resolution process and the diameter of the pipe constantly becomes smaller.

The Vulcan water treatment upsets the natural balance between the build-up of scale and the natural resolution process. Deposits cannot be formed by the mono crystals so the scale build-up in the first instance is lessened. This is enough to allow the natural scale-resolving-process to effectively deal with scale deposits. The scale can no longer form faster than it is removed. The increased amount of carbonic acid can dissolve the scale. The scale build-up in the pipes is gently and gradually dissolved away.

Removing scale = removing rust

Iron particles embed themselves into scale build-up as soon as they are formed. The scale and rust, thus amalgamate into one material that appears in the form of red-coloured sediment in the pipe. When the scale is dissolved by the Vulcan treatment, rust is dissolved at the same time.

These deposits are cleared out by a gentle process that sees the scale being dissolved into the water and washed out in its component elements: calcium, magnesium and iron. This water is completely safe to drink as these are naturally occurring minerals.

Remove scale build-up = removes bacteria

Scale deposits create an ideal environment for bacteria and other less desirable items. Once the Vulcan has worked it’s magic and removed the scale, the environment is no longer ideal for bacteria. In this manner, contamination by bacteria is either completely eradicated or, at least, largely reduced.

3. Rust Damage And Perforation Are No Match For Vulcan

Contact with hard or calciferous water is the reason that copper and/ or iron oxidation occurs in metal pipes. The pipe surfaces are badly affected by these oxides and this may cause the pipes to corrode.

The Vulcan-impulse-technology generates an electrophoresis-effect which produces a protective metal-carbonate layer. Depending on what the pipe is made of, a layer forms on all shiny surfaces – this layer consists of copper-carbonate, iron-carbonate or zinc-carbonate – and acts as a protective barrier against elements in the water that could corrode the pipe.
