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.
