Today, radio frequency converters of the Rapresol series are widespread, which are active in struggle with hardness salts. They can prevent scale inside the pipelines, and are also able to protect heat -reproductive, boiler rooms, technological equipment from the appearance of scale. The appearance of scale on the walls of the pipes entails an additional energy consumption. Locked 1 mm thick, settled on the walls of the pipes, can reduce heat transfer to 10%. This entails an increase in energy consumption. The presence of scale affects the increase in the cost of maintenance, repair of thermal equipment, sometimes an excessive number of scraps disables some sections of thermal systems. Therefore, the appearance of scale must be prevented, and it is not worth delaying this. The absence of scale will save your money, the energy consumption of the energy resource will decrease significantly.
