Electronic Descalers
For Large-Diameter Industrial Pipe
Seven new industrial models have been added to the manufacturer’s UL-listed ScaleBlaster line of electronic descalers. These models handle standard diameters of nonsteel pipe ranging from 12 in. to 40 in. and of steel pipe from 4 in. to 26 in. Signal coils continuously transmit fluctuating square-wave frequencies through the pipe wall to the moving water stream inside. These microprocessor-controlled frequencies cause calcium carbonates to lose their adhesive, scale-forming properties. ClearWater Enviro Technologies Inc.; 800/756-7946; www.scaleblaster.com
