The Eco-Friendly Anti-Scale System

Vulcan is an eco-friendly water treatment system that prevents limescale depositis and rust in your piping system and appliances. The Vulcan-Impulse-Technology is based on the principle of physical water treatment. Special electronic impulses change the crystallization process of the liquid calcium. This way the hard limescale loses its adhesive power. The technology works exclusively with capacitive electric impulses:

The 3 Vulcan Effects

1. Vulcan Effect

1. Vulcan reduces scaling on surfaces

Vulcan modifies the crystallization of the calcium. The limescale loses its adhesive power and is washed away with the water as a fine powder.

2. Vulcan Effect

2. Vulcan sanitizes the piping system

Vulcan carefully dissolves existing incrustations in the piping system. Only a thin protective layer remains in the pipe.

3. Vulcan Effect

3. Vulcan protects against rust and corrosion

Vulcan generates a controlled electrophoresis process, which produces a protective metal-carbonate layer. It acts as protection against rust and corrosion.

10 Reasons for Vulcan

blankGerman 36 Volt Impulse-Technology to control scale in an eco-friendly “green” way. . … more

blankThe Vulcan impulse bands transfers the impulses into the water. Improved transmission up to 40%. … more

blankThe original Vulcan acrylic cast offers maximum protection and keeps all parts secure.

blankVulcan is not magnetic and operates independent of the velocity and constantly provides reliable impulses.

blankMaterial-matching programs: Vulcan treats any pipe material – metal, PVC, plastic, compound pipes, etc.

blankIn case of a power failure Vulcan automatically resets back to the last active program.

blankVulcan holds certifications by numerous institutions: the German TÜV, the German CE, the UL-approval, etc.

blankVulcan requires very little electrical power. The running costs are approx. USD 3-7 (~3-6 EUR) per year.

blankVulcan is a Made in Germany product that has been manufactured by the Christiani Wassertechnik GmbH.

blank 25-year international warranty: The high quality gives Vulcan a life expectancy of 30 years and more.

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.
