How many years of warranty does Vulcan have?

Vulcan has a total warranty of 25 years, plus a service life of 30+ years.
It is certified and marked by TÜV (Germany), CE, UL. Your Vulcan unit is 100% covered in almost all circumstances. The unit, covered with a waterproof acrylic moulding, has a service life of more than 30 years. By purchasing from the manufacturer or from our listed distributors, your warranty will be absolutely secure. German quality standards and excellence in customer service have been our priority for more than 60 years.

What certifications does the equipment have?

Quality indicators – 12 reasons for Vulcan quality

Vulcan has numerous certifications from renowned international institutions: the German TÜV and CE, the

German TÜV and CE, UL approval for adapters, etc.
Vulcan clearly stands out thanks to its quality and performance.

We suggest that you compare Vulcan with other products by combining some quality indicators:
German 36 Volt Impulse Technology (capacitive): the water is treated with electrical impulses that regulate limescale deposits in a “green”, environmentally friendly way.
It is an electrical system that does not work with magnetism.

Vulcan operates in a frequency range of 3-32 kHz with different frequency peaks (oscillating distribution). The secret of a good performance of the physical water treatment lies in the composition of these pulses. CWT has been developing and fine-tuning them for more than 30 years.

Vulcan uses customised, insulated copper impulse bands. The way the impulses are transferred to the water is critical. The belts have a design that increases the surface area that carries the pulses. This increases transmission by up to 40%.

The original acrylic moulding is a unique feature of the Vulcan product line. It offers maximum protection against water, heat, dirt, cold and humidity and keeps all parts securely sealed in place.

Vulcan includes UL and TÜV certified external electronic adapters. The adapters operate on a very low power consumption of 100-240V and can level out any electrical instabilities.

Vulcan does not operate with magnetism. Therefore, it operates 100% independent of the velocity (flow rate of the water) in the pipe, constantly providing reliable pulses that guarantee correct signal output at all times.

Adaptive programmes for different materials: Vulcan can treat any material. There is no need to buy a different product for metal, PVC, plastic, etc.
The automatic memory program guarantees the correct operation of Vulcan.
In the unlikely event of a power failure, Vulcan automatically reverts to its last setting once power is restored.

Vulcan has numerous certifications from renowned international institutions: the German TÜV and CE bodies, UL approval for adapters, etc.
Vulcan requires very little electrical power and is therefore very economical. The Vulcan unit operates between 1.75 and a maximum of 3.25 Watts. The running costs are approx. 3 to 7 $ (~3 to 6 €) per year.

Made in Germany: Vulcan is a German quality product manufactured since 1991 in Berlin by the family-owned company Christiani Wassertechnik.
All Vulcan units come with a 25-year international warranty.

Due to their unique acrylic protection, these units remain in operation with a life expectancy of more than 30 to 40 years.

How much electricity does Vulcan consume?

The electronic unit consumes only 36 Volts, so the electricity consumption is minimal.

With which water hardness can I use Vulcan?

Vulcan operates in a high performance frequency range and is the only device with 24 Volt technology. This means that it can be successfully used to solve problems caused by very high water hardness. Vulcan has been successfully used to treat water hardness of 900 ppm (approx. 53 gpg) or more.

What is the maximum temperature Vulcan can handle?

In addition, scale builds up especially when the water temperature in the system rises, as is the case with heating elements and radiators. The higher the surface temperature, the more limescale deposits develop. These problems can be observed
specifically in heating elements, water heaters and 95°C heat exchangers.

Does it work in any flow rate?

There is a recommended flow rate:
Water capacity
The maximum hourly water capacity (l/h, m3/h, gph or gpm) is the flow rate that Vulcan is able to treat in one hour. This capacity is largely determined by the pipe diameter: the pipe diameter and the maximum water pressure (usually 20 bar) determine the maximum capacity of each specific pipe.

Most of the time – especially in private installations – it is very likely that the customer does not consume the maximum possible capacity (e.g. Vulcan 5000 with a maximum of 8000l/h). However, at peak times, this may be the hourly consumption for a very short period of time. The maximum capacity is reached at times of simultaneous consumption (peak consumption).

For example, peak consumption is reached when the water is running in the kitchen at the same time as someone is taking a shower and the washing machine is running.
As production processes are carefully designed to meet exact needs, it is more frequent in industrial production lines that the maximum capacity of the pipe diameter is consumed over longer periods of time. For example, in industrial settings, a 4″ pipe is more likely to consistently carry the maximum amount of water, for the simple reason that it has been designed exactly for that purpose.

How many Vulcan models are there?

There are 12 Vulcan models designed to protect piping systems, boilers and machinery.
These programmable units allow individual adjustment according to materials and pipe diameter.

There are units for the residential range:
VULCAN residential range.
Commercial range:
VULCAN Commercial Line.
Industrial range:

How does the structure of lime change?

How the structure of lime changes

Vulcan is a physical water treatment system that uses NO chemicals or salts. Nor does it alter the chemical composition of the water. Instead, it changes the physical characteristics of the lime crystals in such a way that the lime particles lose their adhesive capacity. Vulcan does not need to be in direct contact with the water, but is installed outside the pipe.
Vulcan treats the water by means of electrical impulses which are generated in the electronic unit and controlled by a computerised microchip. The signal frequencies are transmitted through the Vulcan impulse bands that surround the pipe. The bands interact in pairs, creating a frequency field that changes the crystals in the water as it flows.

The Vulcan impulse field

The Vulcan impulse bands act in pairs, with a left and a right side. Each side alternately launches a specific signal that is sent 10 times per second into the pipe. The electronic pulse field is generated from frequencies between 3,000 and 32,000 Hz.
Due to the alternation of the signal side – which means that both impulse bands are never active at the same time – the frequencies of the impulse field overlap. This effect multiplies the frequency patterns, which in turn creates specific overtones (harmonics).
Vulcan’s processing is executed with absolute precision, as the one-step pulse generator generates the desired result exactly as desired. It operates completely independently of the flow velocity and as the electricity comes from electrical energy, a continuous flow of pulse field generation is ensured.

Two natural phenomena

Scale deposits build up when the liquid calcium in the water forms crystals that stick together (Fig. 1). Physical treatment of the water creates a different calcium crystal structure that loses its ability to adhere to surfaces and develop deposits.
These new, harmless single crystals (Fig. 2) are the key element of the Vulcan water treatment. Vulcan triggers different processes to produce these single crystals and disinfect the pipes:
a) Separation of the Ca(HCO3)2 through controlled electrophoresis.
The alternating frequencies of the pulse field cause an electronic gradient which manifests its electrical power in the water. This power exerts its influence on the liquid calcium [Ca(HCO3)2], separating its individual components.

This is the origin of the calcium single crystal, which can only develop in two opposite directions and therefore cannot group with other single crystals to form calcareous deposits. Calcium single-crystal formations with a rod shape (Fig. 3) between one (+) and the other (-) end. In this form they lose their ability to stick together and form deposits. During their journey through the pipes they will grow in size.
size. The longer the single crystals are, the better the treatment result.
The separation of the compounds from the water by electrophoresis also changes the balance of calcium and carbonic acid, resulting in a slight surplus of carbonic acid (formula 2). This small increase in free carbonic acid contributes to the cleaning of pre-existing limescale deposits in the pipes.
b) Separation of Ca(HCO3)2 by means of overtone treatment

The Vulcan impulse treatment controls the production of overtones as a result of frequency overlapping. The overtones are programmed to meet the characteristics of a water cluster, which, simply put, is the most basic unit of which water is composed. The extremely short wavelength of the overtone waves is coupled with that of the water clusters so that the two begin to resonate with each other. Just as a high-frequency tone can cause a wine glass to explode when it resonates against the glass, so coinciding the wavelength of the overtone with the water clusters causes the same result: the water clusters explode.
When a water cluster bursts, the same process of separation of Ca(HCO3)2 compounds occurs (compare formula 1). The stronger the effect, the more single crystals will be produced, thus achieving the expected result of dismembering lime and rust.

Single crystals and carbonic acid

Both controlled electrophoresis (a.) and overtone treatment (b.) result in the separation of liquid calcium [Ca(CO3)2] down to its individual components. Thus, Vulcan generates the precious single crystals and the increased level of carbonic acid.
– The single crystals stop the formation of lime deposits on the surfaces.
– Carbonic acid is the key compound for the removal of pre-existing limescale deposits.

Contrary to the typical chaotic cluster form of calcium crystals, the treated crystal develops as a monocrystal.
crystal develops as a well-ordered single crystal (the so-called aragonite form) in the form of a stem running from one end (+) to the other (-).

Where does the lime go?

The lime dissolves slowly and gradually comes out with the water in the form of a fine powder.
in the form of a fine powder.

What effects does Vulcan have on the whole water installation?

1st effect of Vulcan
Vulcan stops limescale deposits in pipes and appliances.
household appliances. Without Vulcan water treatment, the scale particles in the water create sticky crystals that form solid deposits.
Vulcan Impulse Technology modifies the way calcium and magnesium crystallise, using a natural process called electrophoresis. As the crystals become softer and rod-shaped, they can no longer stick together. Thus, the limescale is washed away as a fine powder. The formation of new scale deposits is stopped. The more
The more rod-shaped crystals are created, the more effective the scale prevention effect.
the more effective the scale prevention effect.
Monocrystals – the result of Vulcan water treatment
It is important that the single crystals that are created through pulse variation can grow for as long as possible before they continue their way through the pipes. The larger the single crystals are, the longer it will take them to break up again and eventually dissolve.
In warm water, these crystals grow faster and are therefore stronger and live longer. This explains why the Vulcan effect lasts longer in warm water (up to seven days) and less in cold water (approx. two days).

2nd effect of Vulcan
Vulcan gently disinfects the pipes
Two processes occur simultaneously in untreated hard water:
a. During the first process, calcareous deposits appear as calcium crystals adhere to each other and then adhere to any surface. This first process produces carbonic acid (H2CO3) as a by-product.

b. During the second process, the carbonic acid simultaneously decomposes existing lime deposits.
existing lime deposits simultaneously. This is known as the “natural dissolution process”. As the growth process occurs much faster than the natural dissolution process, the diameter of the pipes is constantly decreasing.
Ca(HCO3)2 + Vulcan CaCo3 + CO2 + H2O
(Calcium hydrogencarbonate+Impulse+Vulcan+Carbon dioxide monocrystals+Water)

The 3 effects of Vulcan
The Vulcan water treatment alters the balance between the scale settling process and the natural dissolution process. The nanocrystals will no longer have the ability to settle and thus the scale formation of the first process is reduced. The natural limescale dissolution process will then only need to treat the already existing deposits and can effectively combat them. In this way it is possible to
reduce limescale faster than it takes to form. The natural excess of carbonic acid dissolves the limescale. The sediment in the pipes will be removed carefully and gradually.

Limescale removal = rust removal

As soon as limescale deposits form, iron particles attach themselves to them. Thus, the scale and the corroded rust merge into a single material, which appears as reddish deposits on the pipes. Once the Vulcan anti-limescale treatment destroys the scale base, all existing rust is removed at the same time.
The removal of the deposits is a gentle process in which the scale is dissolved, which will then flow with the water in the form of calcium, magnesium and iron. There is no risk in ingesting the water, as all these minerals are healthy.
Removal of limescale deposits = removal of bacteria
We know that scale acts as a breeding ground for bacteria and other unwanted micro-organisms. As soon as Vulcan has been installed and the scale has been removed, this breeding ground for bacteria disappears. Thus, bacterial contamination is considerably reduced and can even be completely eliminated.

3rd effect of Vulcan
Vulcan protects against perforations and rust damage
Copper and/or iron oxidation occurs in all types of metal pipes that are in contact with calcareous (hard) water. These oxides seriously affect the entire pipe surface and can cause corrosion.
The Vulcan Impulse Technology creates an electrophoresis effect that
promotes the formation of a protective metal carbonate layer. Depending on the pipe material, this layer can be composed of copper carbonate, iron carbonate or zinc carbonate. This layer is deposited on all shiny metal surfaces and protects the pipes from aggressive substances that could cause rust.

 

Will I have more water pressure after installing Vulcan?

Increased water pressure
Vulcan disinfects pipes, freeing them from scale deposits and even making it possible to completely restore a pipe to its original diameter. The water can flow freely again and you get normal water pressure again.

Will it improve the energy efficiency of my boiler?

Heating
When water is heated by oil, gas, electricity, solar or electrical technologies, limescale tends to settle on the heating elements and heat exchangers. The energy loss in these cases is enormous as a result of less efficient heat transfer. Vulcan helps to reduce scale formation and prolongs cleaning intervals. The water tanks in the primary and secondary circuit will need less care and the frequency of cleaning periods will be extended.
When heating the water in a water heater with or without a tank, hard water always causes
hard water always causes deposits on the heating elements.
heating elements. This limescale coating inevitably results in a considerable reduction of the heat transfer capacity. A scale deposit of only 2 mm can cause an energy loss of more than 15%. The increased heating time results in a significant increase in electricity consumption.

Water heaters
Vulcan permanently controls scale formation in tankless water heaters and reduces the maintenance frequency of the heat exchangers, as less scale deposits occur. Your water heater will run efficiently again and it will be possible to extend the interval until the next service.

Heaters regain full performance
When heating water in a hot water tank, hard water always results in the formation of thick scale deposits on the heaters. This limescale coating inevitably leads to a significant reduction of the heat transfer capacity. With Vulcan, scale deposits are minimised and the heaters operate at full capacity again. Maintenance intervals are extended.
Overall, your water heating bill will be considerably reduced.

Solar water heating
Vulcan prevents scaling in the system, keeps heat exchangers and distribution pipes clean. Vulcan also reduces scale formation in the collectors and protects the hot water tanks and suction pipes, preventing the system from overheating. It eliminates the need for acids in the piping system.
Protection for your solar water heater
Energy savings, which often justify the purchase of a solar water heater, can be drastically reduced by limescale deposits. In this case, a scale layer of only 1 mm (~0.04″) can result in an efficiency loss of up to 40%. With Vulcan you save on energy, cleaning and repairs. This energy loss will have to be compensated through fossil fuels or electrical energy, so your initial saving project will no longer be valid.

Does Vulcan kill bacteria?

Due to their uneven surface, the thick scale deposits are a perfect breeding ground for bacteria.
Once the scale has been removed, the areas where bacteria could nest are also removed.

Does Vulcan work in swimming pools?

As far as the substances in the pool water are concerned, in general there are no limit values that can hinder the treatment of Vulcan water.
However, the pool water needs to be constantly checked and different types of chemicals applied. Vulcan significantly reduces limescale in and around the pool, as well as in the filters, pumps and pipes as a whole.
as a whole. For this reason, once Vulcan is installed frequently, the use of chemicals can be reduced:

Disinfection
Chlorine: The disinfection of the pool water is mainly carried out by treating it with chlorine (Cl). This product is available in granulated, liquid, tablet or stick form. The supply of chlorine can often be reduced by up to 10 to 25%. It is recommended to reduce its use progressively (e.g. starting with a 10% reduction and then increasing).
Active oxygen is used as an alternative disinfection method that does not contain chlorine. The amount of active oxygen can also be reduced. A gradual reduction is recommended.
pH regulating products can either reduce or increase the pH value and control the total alkalinity of the pool water. These products are added to rebalance the pH that has been altered by the use of chlorine or oxygen.
with the use of chlorine or oxygen. Thus, the use of pH regulating products can be reduced in the same proportion that disinfectant products have been reduced. For example, if the chlorine is reduced by 15%,
the pH regulator can also be reduced by 15%.

Pool cleaning
Pool cleaning products are used to combat the development of limescale on the waterline, grids, tiles and surfaces surrounding the pool. Vulcan minimises the formation of limescale,
facilitating the cleaning process and reducing the use of cleaning agents and chemicals by up to 50%.

How does Vulcan improve the irrigation of plants and gardens?

Garden irrigation with sprinklers will be more reliable as the nozzles will remain longer without fouling.
fouling. Plants absorb and process water better when it is treated with Vulcan.
when treated with Vulcan. As the leaves of your plants have less lime scale stains, the plants will look better and will be able to absorb and process the water better.

Can I install Vulcan on any type of pipe?

What kind of pipes can Vulcan treat?
Vulcan works on pipes of all types of material: iron, galvanised iron, copper, steel
galvanised iron, copper, steel, stainless steel, plastic, PVC, PEX, composite pipes
composite pipes (any mixture of materials), etc.

Do I need a plumber to install it?

Most water treatments have to be installed in the pipes and therefore require a professional plumber to install them. Vulcan can be installed in just a few minutes without any help or tools.
This saves money by not having to hire specialist help.

Does the water supply have to be cut off for installation?

Water supply has to be cut off for installation.
No.
As the pipes do not have to be cut to install Vulcan, the water supply does not need to be cut off. The installation of the electronic unit and the impulse bands are wound onto the pipe.

Where is it recommended to install the unit?

Installation in a private home
Traditionally Vulcan should be installed at the point where the main water supply pipe enters the house. In most cases, this point is located near the water meter or the main stopcock. By doing so, Vulcan treatment occurs before the water is distributed into the house.
Often houses in Europe have a basement, where the main water pipe is easily accessible.
The main water pipe is easily accessible. Therefore the installation is uncomplicated. Many other houses in other parts of the world have access to water outside the house. This is usually where the meter is located. CWT also offers a wide range of accessory equipment, such as mounting boxes that protect the unit against theft and weather.

If the house is equipped with a water storage tank (which is often located on the roof), we recommend the installation of Vulcan after the water outlet of the tank. This ensures that the treatment of the water occurs before it starts to circulate through the piping system. If Vulcan is installed before the tank and the water remains there without use for 2 to 7 days, it is possible that the effects of Vulcan will be lost.

Installation in an apartment building
In general, the same procedure applies for installing Vulcan in larger buildings as for private houses: Vulcan should be installed in the pipe segment where the water supply is directed into the building (traditionally this is where the meter is located). Please take other factors into account, such as
the installation plan of the water pipes and the heating system.
If you have an additional heating system, you may need another unit for the hot water circulation pipe. The size of the Vulcan unit must be in accordance with the pipe diameter and the water flow rate.

Installation in business and industry
Due to the varying nature of each production site, no standard installation rules can be established. However, as a general rule, a production plant is made up of a number of individual buildings, so the same treatment can be applied to the main building as to any other large building. We recommend the installation of a large unit to treat the main water intake pipe. This corresponds to the basic treatment. Additional Vulcan units should be installed in those segments upstream of the machinery that cause the worst scale problems (heat exchanger, cooling tower, refrigeration machines, production lines, etc.). Please contact us if you require technical assistance.

Do I need a lot of space to mount it?

There are 12 Vulcan models, depending on the amount of water to be treated.

Each model emits very high frequencies from 3000 to 30000 Hz.
and include impulse bands of different lengths.

So it depends on the model how much space is needed for installation.

What do I have to consider when choosing a Vulcan water softener?

Two factors are important:

The diameter of the pipe.
The water capacity.

For example in a house with up to 3 bathrooms and a pipe size of less than 38mm the correct model would be the Vulcan 3000.
If it is a villa or house, with up to 6 bathrooms and a pipe size of less than 50mm, the correct model would be the Vulcan 5000.

However, we recommend that you consult our technical department to advise you on the correct choice.

What are the installation requirements?

Surface:
The equipment consists of an electronic unit and impulse bands that are wound onto the pipe.

A minimum surface area is required to mount these bands.
There are 12 models, depending on the equipment to be installed. If there is no space, a plumber can add a bypass to the piping system.

Electrical connection: A socket is required to connect the electronic unit which consumes only 36 volts.

Can I install the water softener myself?

Vulcan is specially designed so that the installation does not need to be carried out by a specialised plumber. You can easily install Vulcan in approx. 10 to 15 minutes. The installation requires no tools and there is no need to cut the pipes.

You can see how it is done in the following video:

See training manual 11.4 Basic installation : do-it-yourself installation

Vulcan is specially designed so that the installation does not need to be done by a specialised plumber. You can easily install Vulcan in approx. 10 to 15 minutes. The installation requires no tools and there is no need to cut the pipes.

11.4.1 Installation instructions
1. For effective use Vulcan must be mounted in the area of the water meter, i.e. in the main water pipe.
2. The drive belts can be wound with a distance of 1 cm (1/2″) to the left and right side, as well as underneath the electronic device.
3. Vulcan can be mounted horizontally and vertically in all directions.
4. If space is limited, the coils can be installed on one side in the main tube and on the other side in the distribution tube.
All types of installation mentioned here are possible, as the treatment impulses extend over several metres in all directions of the ducts.

11.4.2 General instructions
1. Protect the socket from moisture and water.
2. Use only the original adapters of the device.
3. Do not cut the drive belts or the 36 V power cable of the power supply unit.
4. Do not remove the covers from the ends of the drive belt insulation.
5. Vulcan operates with an operating temperature of -25°C to 50°C.
6. Clean the device only with a damp cloth.
7. The temperatures in the heat exchanger should not exceed 95°C.

Can Vulcan be installed outdoors?

Vulcan is suitable for outdoor installation. It operates in temperatures between -25°C and +50°C (-4° to 112°F).
We recommend protecting acrylic units installed in any outdoor environment from rain and direct sunlight. Vulcan outdoor covers are available in different sizes and include a cover that can be transparent or opaque. The cover provides extra protection against heat, rain and other external factors. Since the non-transparent cover does not allow the unit to be seen, it makes theft attempts less likely.

My copper pipes have turned green, can Vulcan solve this problem?

When copper pipes show a green colouring it is synonymous with oxidised copper, or copper “rust”, a phenomenon similar to that of copper pipes.
oxidised copper, or copper “rust”, a phenomenon similar to that of iron pipes.
iron pipes. The treatment with Vulcan produces hydrogen dioxide (H2O2)
which protects the copper surfaces against oxidation. In this way
Vulcan reduces the green colouring of the water.

Can the equipment be installed in water from wells, ditches and cisterns?

With wells, water is extracted from deep in the ground, which often results in high levels of calcium, magnesium and other minerals in the water. As a result, the water quality usually ranges from very hard to extremely hard. The Vulcan treatment offers an excellent solution to this. As a rule, the Vulcan unit should be installed upstream of the suction pump, if possible at a distance of about 1.5 m (3.5 ft).
1.5 m (5 ft) from the pump motor. For submersible pumps it is recommended to install Vulcan at the outlet of the hydrophore basin. Water quality: Well water may also contain other substances such as iron or manganese. Check beforehand by water analysis.

How to measure water hardness - Limescale test

Your water company can provide you with detailed information about the chemical composition of your water. This information usually indicates the calcium and magnesium content of the water, as well as the degree of hardness of the water in gpg (grains per gallon) or ppm (parts per million).

Does Vulcan eliminate water hardness?

This treatment does NOT change the hardness of the water. Unlike chemical water treatments (e.g. salt-based water softeners), Vulcan treated water does not lose minerals such as calcium and magnesium.

But above all, the limescale loses its adhesion. However, this treatment does not alter the measurable hardness of the water. This
This means that on a chemical level, you will retain the same water hardness before and after treatment.

If I do a limescale analysis after installing the equipment, will I have less limescale?

If I do a limescale analysis after installation, will I have less limescale?

No. This treatment does not change the hardness of the water. Unlike chemical water treatments (e.g. salt-based water softeners), Vulcan treated water does not lose minerals such as calcium and magnesium.
Therefore, if we analyse the lime content after Vulcan, it will be the same.
This analysis is only useful to know the content of this mineral, but not the structure of the lime crystals, which can only be seen through a microscope.

voltage or contact your local dealer.

How long does Vulcan take to clean the pipes?

Vulcan gently removes limescale and rust without affecting the pipes. The treatment works according to the principles of nature. Thus, the descaling procedure can take as long as it has been necessary for the deposits to become encrusted.

Can descaled limescale clog pipes?

No. The lime dissolves slowly and gradually comes out with the water in the form of a fine powder.
in the form of a fine powder.

Do you need to maintain or change anything periodically?

Once you install the Vulcan unit and its impulse bands on the pipe and plug the unit in. You don’t have to worry about anything else. The unit breaks down the limescale and also cleans the pipes of rust and old limescale.

Will it help me dissolve the old limescale in my pipes?

Two processes occur simultaneously in untreated hard water:
a. During the first process, calcareous deposits appear as calcium crystals adhere to each other and then adhere to any surface. This first process produces carbonic acid (H2CO3 ) as a by-product.

b. During the second process, the carbonic acid simultaneously decomposes the existing lime deposits.
existing lime deposits simultaneously. This is known as the “natural dissolution process”. As the growth process occurs much faster than the natural dissolution process, the diameter of the pipes is constantly decreasing.

Will it help me dissolve the rust in my pipes?

When copper pipes show a green colouring it is synonymous with oxidised copper, or copper “rust”, a phenomenon similar to that of iron pipes. The Vulcan treatment produces hydrogen dioxide (H2 O2) which protects the copper surfaces against oxidation. In this way Vulcan reduces the green colouring of the water.

How will Vulcan protect the pipes?

Vulcan protects against rust and corrosion.
Once in contact with aggressive water, all metal pipes – especially copper, iron and galvanised iron pipes – accumulate copper or iron oxidations. These oxides seriously damage the
and lead to corrosion.
Thanks to its electrophoresis effect, the Vulcan impulse technology promotes the formation of a protective metal carbonate layer.
Depending on the pipe material, this layer will consist of copper, iron or zinc carbonate, which can be found on shiny metal surfaces. In this way Vulcan protects your piping system from rust and corrosion.

Vulcan electronic water softener vs. magnetic system

It works with magnetism

Vulcan is NOT a magnetic system

It works exclusively by impulses. The energy it needs comes simply from a power socket.
It is essential for us to establish a clear distance between our technology and those devices that use magnetic force to treat water.
Why avoid magnetism when treating water Physical water treatment devices that work with magnetism produce electrical impulses by induction. This means
This means that the magnetism must generate complex electrical impulses together with the water that is transported through the pipe. As we will see below, this happens only sometimes. Thus, the following problems related to magnetism cannot be ignored:
Magnetism problem: not all types of pipes can be treated equally effectively Since the magnetic field of the magnet does not easily pass through metal, many distributors prefer to install the device in plastic pipes. If the installation site is a metal pipe, they recommend cutting a segment of the pipe and replacing it with a segment of plastic pipe.
replace it with a segment of plastic pipe.

We consider this to be an unnecessary additional complication. Magnetism shows its limits in water treatment in general, and furthermore, it should be
installed only in plastic pipes. Magnetism problem: magnetism itself Magnetism is in fact a very powerful force. It is recognised as having many positive attributes for the organism. However, we all know that magnets attract metallic objects, no matter how small they are. This brings us to another serious problem linked to the use of magnets in ducting. The area where an electromagnetic system or magnet is permanently installed becomes – of course – magnetic. There, all metallic particles contained in the water will adhere firmly to the inner side of the pipe. The same is true for both plastic and metal pipes. After a short period of time, the inside of the pipe is covered with a dirty film of metal particles (biofilm), which lends itself perfectly to the reproduction of bacteria or other unwanted substances. As a solution to this problem, many manufacturers of magnetic devices suggest deactivating the equipment every six months and “flushing” by circulating water through the ducting.

We believe that the formation of a potentially dangerous biofilm by means of magnetism to treat pipes is not a smart way to solve fouling problems. We also know that cleaning the pipes by flushing or brushing can be avoided. The answer is: no to the use of magnetism.

Magnetism problem: velocity

The creation of a complex electric pulse field is only possible if the water inside the duct flows through the magnetic field at a high velocity (= velocity / flow velocity) of at least one metre per second (~ min. 3.3 ft/sec). If this occurs, then
the pulse will be generated. But if the flow velocity is not adequate (if it is too slow), the pulses will not be generated efficiently.

We believe that a perfect and stable electric pulse field should be generated simply by sending signals through the drive bands. For this reason, Vulcan is
For this reason, Vulcan is a purely electrical technology. Its annual electricity consumption is minimal and amounts to approx. 3 to 5 € (~ 5 to 6 $).

 

Vulcan electronic water softener vs. ion exchanger (with salt)

Vulcan is an electronic (capacitive) impulse based,
eco-friendly water treatment system that solves your
problems with scale and rust. However, there are other
units available that are based on other principles.

Salt-based water softeners (so-called ion-exchangers)
are using salt and chemicals to treat the water. They
are installed into the piping system which should only
be done by a professional plumber. They exchange the
minerals (calcium and magnesium ions) with twice as
much sodium (salt) ions. As calcium and magnesium
gets deleted, the water is softer afterwards. This way
softeners considerably increase the sodium content of the
water which can cause considerable health threats and
certainly is a threat for the environment.
Burning money: Regular water softeners are not only
expensive to purchase but also you will need a specialist
to do the installation. Once in place you will have to
constantly refill it with salt. Never-ending maintenance:
Maintenance includes the constant refilling with salt, the
washing of the granule and the checking of valves and
measuring station.
Wasting resources: Softeners require large amounts of
salt and huge amounts of additional water of up to 30-80
gallons per wash (~110-300 l) to operate.
Water softeners need a lot of manpower as they constantly

need to be fine-tuned and controlled. Especially season-
related changes of the water quality (summer/ winter)

where the programming changes are often simply
forgotten to be considered. The human error factor then
prevents the unit from performing correctly.
Health issues: Babies, children, elderly people, people
with salt restricted diets or anyone who is health-conscious
should consult a physician regarding the sodium intake
increase when using a water softener. The water loses
its natural taste and may even taste salty. Also you may
have to supplement the important minerals calcium and
magnesium in your daily diet.

It is important to note that many of the water softeners
have a bypass feature that will allow you to bypass the
cold water in the kitchen. This will enable you to use
unsoftened water for drinking and cooking. In addition,
bypassing the cold water tap in the kitchen will prevent
minerals from being removed from the water. However,
then only part of your pipes are protected.
Water softeners make your water softer. But
… is that always a good idea?
… is it necessary to have extremely soft water?
The answers are simple: No and No.
Hard water is a real nightmare as long as the scale builds
deposits. The minerals calcium and magnesium in itself
are good substances. Once you minimize the adhesiveness
of the scale, it no longer bothers you as deposits but you
can benefit from the healthy minerals. Very soft water is
also not recommended for pipes as is may cause damage
(soft water is very high in acidity).

There are similar electronic water softeners with other names, are they the same?

I have heard that products of this type are useless, can you clarify this for me?

There are products on the market that look similar to Vulcan and claim to be able to deliver on their promises, but they don’t. The vast majority of similar products work with electromagnetic (inductive) technology. The vast majority of similar products work with electromagnetic (inductive) technology.

They are easily recognisable by their cables: the cables of such equipment exit the electronic equipment, pass through the pipeline and return to the equipment again, forming a closed circuit (Figure 1).

Vulcan, on the other hand, works exclusively with capacitive pulses, which ensure a regular and stable output of these pulses. Its bands terminate in the pipe, fulfilling a function similar to that of an antenna. But regardless of whether the pulses are inductive or capacitive, Vulcan uses much wider frequencies ranging from 3,000 to 32,000 Hz (3 to 32 kHz) and operates at 36V power levels.
