Yes. Plastic and copper pipes are also susceptible to calcification.
The smoother a surface is, the longer it can resist the calcification process.
It may take longer for an initial layer of limescale to form on plastic or copper. However, once that initial layer has formed, the calcification process progresses just as quickly as on any other surface or material.

Limescale deposits also provide an ideal breeding ground for bacteria, algae and other undesirable microorganisms. Because the deposits have an uneven, rough surface, these small caves provide ideal nesting areas for bacteria and algae.
Whether you use cold or warm water, you will notice an increased number of potentially dangerous substances deposited on limescale.
Vulcan removes these limescale deposits and thus reduces the proliferation of microorganisms.

Vulcan gently removes limescale and rust without negatively affecting the pipes.
Depending on how much limescale is present in the pipes, the removal will take a few weeks or months.

No, the lime is slowly dissolved again and is washed away with the water as a fine powder or small pieces.

When single crystals are created by the pulse variant, it is important that they grow for as long as possible before they make their way through the pipe system.
The larger the crystals, the longer it takes for the crystals to break apart and eventually “die”. In warm water, these crystals grow faster and are therefore stronger and live longer.
This explains why the Vulcan effect lasts the longest in warm water (up to seven days) and shorter in cold water (about two days).

Green colored copper pipes are an indication of oxidized copper or copper rust, similar to rust on iron pipes.
When treated with Vulcan, hydrogen dioxide (H2O2) is produced,

The vulcan effects begin immediately after installation.

Vulcan works in a high-performance frequency range and is the only device with 36 volt technology.
It can therefore be used successfully to solve problems with very high water hardness.
Vulcan can treat water with a hardness of more than 100 dH and more.

In contrast to chemical water treatment systems (e.g. a water softener that uses salt), water treated with Vulcan does not lose minerals such as calcium and magnesium.
The natural composition of the elements in the water remains the same.
The change in the lime crystals changes the surface tension of the water. Your skin feels noticeably softer.
You will feel this effect when you shower or even just wash your hands. The saponification is much stronger, more foam develops. On a chemical level, the water has the same hardness before and after the treatment.

The Vulcan device and the pulse bands are located outside the pipe. The pipe does not need to be cut open. Installation is very simple and does not take long.

You can also install the small Vulcan devices model 3000 and 5000 yourself. No tools are required.

Vulcan is installed outside the pipe without the need to cut the pipe. It should be installed where the incoming water pipe enters the house so that protection can be provided for all pipes. Most often this is near the water meter.
Many houses have a basement or utility room, so the main water pipe is located somewhere inside the house.

In private homes, one unit is enough to supply the whole house. In larger buildings or industrial plants, it depends.
Typically, a larger unit is installed on the water supply line to the building. If you have a cooling tower or a closed circuit, another unit is mounted there.

Vulcan works with 36 volt pulse technology and is completely maintenance-free.
The energy costs are only 4 – 6 euros per year, depending on the size.

Vulcan works reliably up to 95°C.
In extreme heat, such as with heating elements with more than 95°C on the heating surfaces, the Vulcan treatment can greatly reduce the effect.

However, we also have cases where the effect has produced successful results even at these temperatures.

Basically, the hotter the surface from 95°C, the less effective the effect can be. The only thing that helps here is to try and observe.

If the mono-crystal is exposed to too much heat, it deforms back into its original crystal structure (the encrusted, burdock-like lime).

Heating systems maintain their full performance.

When water is heated in a hot water tank, the hard water always leads to deposits on the heating elements. These deposits inevitably lead to a sharp reduction in heat transfer capacity.

With Vulcan, the deposits are minimized and your heating system works again
at a much higher performance.

A limescale deposit of just 2 mm can lead to an energy loss of more than 15%. The extension of the heating time leads to a huge increase in your electricity consumption.

The maintenance intervals are extended. In general, the bills for hot water heating are reduced.

In water heaters, hard water always leads to deposits on the heating elements. These deposits inevitably lead to a sharp reduction in heat transfer capacity.

When Vulcan is installed before a reverse osmosis system, it helps with:

1. Because the calcium crystals are smoother after the Vulcan treatment, deposits on the delicate filter membranes are reduced.
The osmosis system runs longer and more effectively.

2. The residual water is difficult to handle because it is precipitated after filtration

There are similar looking products like Vulcan on the market that claim to do the job but don’t.

Almost all other products on the market work with inductive (electro-magnetic) technologies.

You can easily identify them by their brackets or cables.

These cables run in a loop from the electronic unit to the pipe and back into the unit (picture 1)

In comparison, Vulcan works exclusively with capacitive pulses,
which guarantee stable performance. Its pulse bands end at the pipes, similar to antennas.

In addition, Vulcan works independently of inductive or capacitive pulses. Vulcan uses much wider frequencies of 3,000 – 32,000 Hz (= 3-32 kHz) and works with energy levels of 36 V.

Christiani Wassertechnik (CWT) is the oldest German manufacturer of physical water treatment equipment. Their product specialization in this field began in 1977 and since then they have been constantly developing new technologies.

Vulcan is an environmentally friendly water treatment system based on electronic (capacitive) impulses.

Salt-based water softeners (so-called ion exchangers) use salt and chemicals to treat the water. They are installed in the pipe system and should only be fitted by a professional installer.
They replace the minerals (calcium and magnesium ions) with twice as many sodium (salt) ions.
By removing calcium and magnesium, the water is softened. In this way, softeners significantly increase the sodium content of the water,
which brings with it significant health risks and environmental impacts.

High costs: Conventional water softeners are not only expensive to buy, but also require a specialist to install. Once the water softener is installed, you will need to keep refilling it with salt.

Endless maintenance:
Maintenance involves constant refilling with salt, washing the granules and checking valves and the measuring station.
Water softeners involve a lot of effort as they must be constantly adjusted and checked.
Human errors can prevent the device from working properly.

You protect the environment!
The environment and water resources are a valuable asset.
We need large amounts of fresh water, but only 2.5% of the earth’s water content is fresh, and more than two-thirds of it is frozen in glaciers and ice caps.
The use of water softeners contributes to a reduction in the available fresh water on our planet.
It is therefore important to use environmentally friendly technologies and regulate environmental pollution.

Magnetic physical water treatment devices produce electrical impulses by induction.
This means that the magnet(ism) together with the water flowing through it should generate complex electrical impulses.
This is sometimes achieved.
However, the following problems regarding magnetism should not be ignored:
> Since the magnet cannot penetrate metal pipes well, many distributors recommend that their systems only be installed on plastic pipes.
> Flow velocity of the water:
A complex electrical impulse field can only be built up if the water flows through the magnetic field at high speed (= speed/ flow rate) with a minimum of about one meter per second.
When this happens, the impulse can be generated. However, if the flow rate is not high enough, the impulses are not generated efficiently enough.

Everyone also knows that magnets attract metal objects, no matter how small they are. This in turn creates a big problem when magnets are used on or in a pipe system.
The area in which electromagnetic systems or permanent magnets are mounted is of course also magnetic. Magnetic particles in the water tend to stick to the inside of the pipe. This happens to metal and plastic pipes alike.
After just a short time, the inside of the pipe can be covered with a layer of metal, dirt and particles, which in the worst case creates an ideal breeding ground (biofilm) for bacteria or other undesirable substances.
Many manufacturers of magnetic devices therefore recommend turning off the device and “flushing” the pipes every six months.

By using the environmentally friendly Vulcan water treatment, you save time and money from day one.
It is a solid investment for your home that quickly pays for itself:
It protects the entire piping system in your home
It reduces existing deposits
It helps protect appliances such as washing machines, dishwashers, water heaters, heating systems, etc.
You save on maintenance costs and repairs
Filters, shower heads, fittings and tiles stay clean
Vulcan saves on detergents, additives and fabric softeners.

Vulcan improves the performance and efficiency of many machines that use water. Using Vulcan saves you time and money from day one of installation.

Six typical areas of savings:

1. Calcification within the machine is minimized.

2. When additives are used, they are often more effective and last longer.

3. The machine can run longer before it needs servicing again.

Cleaning the parts is often much easier.

4. Fewer repairs and less need to replace individual parts.

5. Tanks that hold water or other liquids require less maintenance and cleaning. Most of the time it is much easier and quicker. This reduced maintenance time results in less production interruption.

6. Less biofilm and bacterial growth allows for a reduction in control measures and chemicals to control.

A single green light indicates correct power supply.
If it is off, there is no active power supply and Vulcan cannot operate. This may be caused by a power plug malfunction. Please check that the power plug is properly connected to the power source. Please also check that the pulse bands are undamaged. If both are OK, there may be a power supply malfunction.

The flashing of the red indicator lights indicates that the pulse generation is working correctly. If the red indicator lights do not light up even though the power supply is active, the pulse generation may not be working properly. In this case, please contact us.

Although the green lamp is off, indicating the lack of power, the red lamps confirm the correct pulse generation. In this case, the green lamp is simply out of order due to a lamp malfunction.

This is a completely normal effect if old limescale deposits have existed.
The first layer of limescale deposits in the pipe is quite loose and crumbles away easily. It is typical to find them within the first few weeks after commissioning. After this first loose layer has broken down, you will normally no longer notice any of the deposits as the limescale dissolves in the water and is washed away.

Because the water in the house has been standing in the pipes for a few days or weeks, it has absorbed the rusty color of the deposits. The red color can then be seen until all the water in the pipes has been flushed out and then new water is pumped through.
This is by no means due to Vulcan. Rather, the presence of red water in such a case simply proves that there are rusty deposits in the pipe system. Vulcan will slowly dissolve these completely.

There are several possible reasons for discoloration of the acrylic surface.
The Vulcan surface should only be cleaned with a damp cloth and without cleaning additives. A common mistake is the use of
a glass cleaner (e.g. Windex), which attacks the material.
Another possible reason is direct exposure to sunlight. This can also lead to discoloration of the surface. However, this is a cosmetic problem and does not affect the effectiveness of the treatment. We offer a re-polishing service in such cases for a small fee.
