During the operation of the heat exchanger, a huge amount of coolant passes through the system, which may contain various kinds of pollutants such as sand, silt, salts, various microorganisms, metal oxides and corrosion products... Settling on the technological surfaces of the equipment, they cause an increase in hydraulic resistance and deterioration of the thermal conductivity of the system, which will lead to a decrease in thermal efficiency, a decrease in service life, an increase in energy consumption to maintain the specified parameters.
The only sufficient measure that can eliminate unforeseen additional costs, untimely repair or replacement of heat exchangers is their regular cleaning.
