To provide equipment for suppressing the deposition of scale components from circulating water passing a water flow pipe in a water circulating system in a cooling tower, heat exchanger, boiler, etc.

This electrode type scale components deposition suppressing equipment suppresses the deposition of the scale components in the circulating water by arranging a pair of electrodes 2 and 3 apart a spacing disposed therebetween so as to face each other within the water flow pipe 1 connected to the circulating system of the water and impressing an AC voltage between these electrodes 2 and 3. The equipment is provided with a controller 4 for controlling the product (VA value) of the load voltage between a air of the electrodes 2 and 3 and the current value to be measured within a preset range.
