eco friendly solution to hard water

Vulcan is an eco-friendly water treatment system that prevents limescale built-up and rust. The Vulcan-Impulse-Technology works on the principle of physical water treatment. Electronic impulses modifies the crystallization process of the liquid calcium, so the hard limescale loses its adhesiveness. The technology works only with capacitive electric impulses.

    The Vulcan full acrylic cast

    The acrylic cast ensures that the circuit board is protected. The parts are fully covered in acrylic. Therefore the parts can not move and are fixed in place. This guarantees a high life expectancy.

    The full body acrylic cast protects from dust and dirt e.g. when installed in a basement. The full body acrylic cast protects against heat and protects against coldness as acrylic is a perfect isolating material. E.g. when installed in extremely hot areas with outdoor temperature up to 50°C ( 122 °F) or in very cold temperatures down to -25°C (-13°F).

    The acrylic cast ensures a very long product life. The most common cause of a malfunction in electronic devices is that they “blow” when the electricity heats up too much. The thick acrylic covering together with the vacuum prevents heat production. This “cooling” of the unit ensures a long life.

    Ten reasons to use the Vulcan descaling solution for hard water

    1. German 24 Volt Impulse-Technology to control limescale in an eco-friendly “green” way.
    2. The Vulcan impulse bands transfers the impulses into the water, what improves the transmission up to 40%.
    3. The Vulcan acrylic cast offers maximum protection and keeps all parts secure.
    4. Vulcan is not magnetic and operates independent of the velocity and constantly provides reliable impulses.
    5. Material-matching programs: Vulcan treats any pipe material.
    6. When a power failure comes up, Vulcan automatically resets back the last active program.
    7. Vulcan has certifications by numerous institutions: TÜV, CE, UL, etc.
    8. Vulcan needs little electrical power. The running costs are approx. USD 3-7 (~3-6 EUR) per year.
    9. Vulcan is a high quality Made in Germany product that has been manufactured by Christiani Wassertechnik in Germany.
    10. 10 years warranty: The high quality gives Vulcan a life expectancy of 30 years and more.

    Frequently Asked Questions

    How does Vulcan Technology work?

    Vulcan is a physical water treatment system that does NOT use chemicals or salt. It does not change the chemical composition of the water. Instead, it changes the physical characteristics of the limescale crystals in a way that the limescale particles lose their adhesive power. Vulcan does not need to have direct contact with the water and sits outside of the pipe.

    It treats the water with electric impulses which are generated in the electronic unit and are controlled by a computerized micro-chip. The signal-frequencies are transmitted via the Vulcan-impulse-bands that are wrapped around the pipe. The bands interact as pairs and form a frequency-field that changes the crystals in the water as it flows by.


    What sort of problems does Limescale cause?

    • Blocked piping systems
    • Dull surfaces and malfunctioning machinery
    • High costs for heating
    • High expenses for cleaning
    • Rust accumulation in the pipe that leads to corrosion
    • Bacterial growth in drinking water carrying pipes
    • Decrease in productivity
    • and many more …


    How does Vulcan help to solve these problems?

    1. Vulcan reduces scaling in pipes and appliances

    Without the Vulcan water treatment, the limescale particles in the water form sticky crystals that then build solid deposits. The patented Vulcan-Impulse-Technology modifies the crystallization of calcium and magnesium using the natural process of electrophoresis. The crystals become smoother and rod-shaped and can no longer attach to each other. Limescale is now washed away in the water as a fine powder. The formation of new deposits is stopped. The more rod-shaped crystals that are created, the stronger the positive effect of limescale-prevention.

    Mono crystals as a result of the Vulcan water treatment

    When mono-crystals are created by the impulse variation, it is important that they grow as long as possible before they start their way through the piping system. The larger the crystals, the longer it takes until the crystals fall apart again and eventually “die”. In warm water, these crystals grow faster and therefore are 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 (approx. two days).

    2. Vulcan gently sanitizes the piping system

    Two simultaneous processes take place in untreated, hard water:
    a. In the first process, limescale deposits result from calcium crystals adhering to each other which then adhere to surfaces. This first process produces carbonic acid (H2CO3) as a side product.
    b. During a second process, the carbonic acid simultaneously breaks down the existing limescale deposits. This is referred to as the “natural resolving process”. Because the build-up process takes place much faster than the natural resolving process the pipes’ diameter constantly decreases.

    Ca(HCO3)2 + Vulcan -> CaCo3 + CO2 + H2O

    The Vulcan water treatment changes the balance between the scaling process and natural resolving process. The mono crystals can no longer form deposits, therefore the limescale build-up of the first process is reduced. The natural limescale-resolving-process now needs only to deal with existing deposits and can effectively combat them. Thus limescale is removed faster than it forms. The natural surplus of carbonic acid dissolves the limescale from the limescale. Gradually and carefully, the deposits in the pipes will be removed.

    The reduction of scale = the reduction of rust

    As soon as limescale deposits have built up, iron particles imbed into it. Thus, the limescale and the rust blend into one material that are seen as red-colored deposits in the pipe. When the Vulcan treatment dismantles the scale, it simultaneously reduces also rust with it.

    Clearing out the deposits is a gentle process where limescale is brought back into solution and washed out in the water as: calcium, magnesium and iron. It is absolutely save to drink as these are all healthy minerals.

    The reduction of scale = the reduction of bacteria

    We know that limescale acts as a breeding ground for bacteria and other unwanted substances. As soon as Vulcan is installed and the scale is reduced, the bacteria breeding ground is also reduced. This way, bacterial contamination is greatly reduced or even fully removed.

    3. Vulcan protects against rust damage and perforation

    Copper and/or iron oxidation occurs in all metal pipes through contact with calciferous (hard) water. These oxides seriously affect the pipe surfaces and may lead to corrosion.

    The Vulcan-impulse-technology generates an electrophoresis-effect which produces a protective metal-carbonate layer. According to the material of the pipe, this layer consists of copper-carbonate, iron-carbonate or zinc-carbonate and settles on all shiny metal surfaces. It protects the pipe from aggressive substances which could lead to corrosion.

    The Vulcan impulse bands

    Vulcan operates with customized isolated copper impulse bands that are designed to firmly connect to the pipe. They are extremely thin and flexible with minimized isolation. This way, they achieve minimal spacing loss and maximize the direct-contact-ratio to 97.5%. Their special copper material with a high alloy purity degree guarantees the best possible transfer output. The copper treatment bands are a crucial factor to the performance of the water treatment.

    The pipe diameter/treatment area ratio
    The impulse bands cover the surface area that is vital for the treatment. The surface of the pipe that is covered by the impulse band is the “treatment area”. This area needs to be large enough to ensure that the impulses are transmitted through the pipe.
