Scalewatcher® is a unique, efficient, energy-saving device designed to eliminate the problems of hard water, while retaining the natural benefits. This is achieved by changing the size of the particles of precipitated compounds, by aiding the ability of crystals to form their shape, and by altering the solubility of compounds within liquid.
Scalewatcher® takes the process of induced ionisation to its ultimate stage. The principles of Magnetohydrodynamics (MHD) is a science discovered in1832 by famous English physicist and chemist, Michael Faraday that has since been applied to many areas such as the nuclear and metallurgy industries. This science is applied by passing Scalewatcher®'s patented signal through a coil wrapped around the pipe to be treated. The signal consists of a frequency modulated (FM) wave form within the audio frequency (AF) bandwidth. This inaudible sonic frequency signal sets up a dynamic field around and through the coil, pipe and water, and modifies the calcium carbonate crystal nuclei.
Magnetohydrodynamics involves magnetic fields (magneto) and fluids (hydro) that conduct electricity and interact (dynamics).MHD technology is based on a fundamental law of electromagnetism: When a magnetic field and an electric current intersect in a liquid, their repulsive intersection propels the liquid in a direction perpendicular to both the field and the current.
The nuclei upon which the crystals start growing are minute in size and have charged surfaces in their natural condition within the water. When they pass through the field, these naturally charged nuclei encounter considerable forces as the field interacts with them. The field acts at the surfaces of the nuclei and modifies the nature of the electrical charges and this ionisation effect thus alters the growth rate and pattern of the crystals in general and on specific planes.
These crystals are harmless, neutral, heat resistant, and completely stable and will not attach to any surfaces like your pipes and heaters to cause lime deposits. When the crystals reach a size in the range of nano-meters (one billionth the size of a meter) they detach and are carried away by the water flow. These nano-crystals are relatively insoluble, effectively isolating hardness up to 25 grains/gal. (420 mg/L) from the water chemistry.
