An environmentally friendly product, the ScaleBlaster eliminates formation of limescale deposits in pipes, cooling towers, boilers, and other applications. The equipment is comprised of a computerized control box and a signal cable that is wrapped around the outside of the pipe. The integrated circuitry system produces a complex modulating frequency waveform that hits the resonant frequency of the calcium molecules, causing them to lose their adhesive properties. Existing scale is removed and never forms again without the need of chemicals, salt, or maintenance. It can be used in residential, commercial, and industrial installations.
