How It Works

Vulcan is a physical water treatment system that does NOT use chemicals or salt. It does not change the chemical mixture of the water. Instead, it changes the physical characteristics of the scale crystals in a way that the scale 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.
