Hard water causes scale to build up in pipes, washing machines and hot water systems. Showerheads become blocked and scale forms on baths, basins and taps. Once installed, the Scalewatcher will remove existing scale and prevents futher build up.

Scale
watcher´s patented technology works by producing a complex frequency modulated waveform. Reacting to the varying applied field the Scalewatcher creates an induced electric field inside the pipe whereby the crystal growth of scaling minerals in the water is promoted. Crystals remain suspended in solution and no longer contribute to the build-up of hard pipe wall deposits. Existing scale layers are softened and loosened scale crystals are removed from the system by the waterflow.

The so-called Lorenz Force decribes the total force on charged particles and ions in a magnetic and/or electric field:
F = q . E + q . v x B N
Where F is the Lorenz Force expressed in Newton, q the charge of a particle or ion expressed in Coulomb, E the electric field strength in Volt/meter, v the velocity of the particle or ion expressed in meter/second and B the magnetic induction expressed in Tesla. F, E, v and B are all vectors. So the incoming particles and ions in the water are subject to this Lorenz Force.
