ClearWater Enviro Technologies industrial sized ScaleBlaster descalers handle standard diameters of non-steel pipe from 12 in. to 40 in. and steel pipe from 4 in. to 26 in. Never actually touching water, the units operate by transmitting oscillating low-frequency radio waves through pipes to the moving water stream inside. The waveforms affect limescale-forming calcium and magnesium carbonates so they become non-adhesive. As a result, new scale does not form and existing scale wears away, says the company.
