What is the effect if there is scale in the cooler?

Limescale effects:
Magnesium ions and acid carbonate. There is formation of carbonates. In addition, rust is formed. Due to the generation of rust, the heat exchange effect is reduced. Make the heat exchange effect useless. Save energy and prolong the service life of equipment.

Affect performance:
(1) The impact of the compressor unit: due to the poor quality of the cooling water, the dirt formed in the cooler has a large thermal resistance, which makes the cooler unable to operate normally, resulting in the deviation of the inlet and outlet parameters of each stage in the compressor, which affects the relationship between the stage and the compressor. The matching performance between the stages reduces the efficiency of the compressor, reduces the processing gas volume, increases the energy consumption of the unit, and reduces the overall performance of the unit. Finally, the output of the air separation unit will decrease, the energy consumption will increase, the operation cycle will be shortened, and the adjustment range of variable working conditions will be reduced.
(2) The influence of the refrigerator: The dirt formed by the cooling water has a large thermal resistance, which makes the condenser in the refrigerator unable to operate normally. The condensing pressure and temperature of the refrigerant increase, which reduces the cooling capacity of the refrigerator, which leads to an increase in the temperature of the air leaving the air cooling tower and entering the molecular sieve purifier, which reduces the adsorption capacity of the molecular sieve, which will also shorten the operating cycle of the air separation unit.
(3) Impact on the pre-cooling system: For the air pre-cooling system, when the water quality is poor, dirt will also form on the components in the air cooling tower (such as sieve plates, packing), thus reducing the replacement of the cooling tower. The thermal efficiency increases the air temperature and also affects the adsorption capacity of the molecular sieve, resulting in a shortened operating cycle of the air separation unit.

Prevention of Effects:
To prevent the generation of cooler scale, it should be controlled from the source, which can ensure the good operation of the system and reduce losses to the greatest extent. In addition, you can also use an electronic descaling instrument, such as the Dekele electronic descaling instrument. Its principle is to use comprehensive radio waves to change the physical structure of calcium and magnesium ions in the water to become new crystals that are insoluble in water, and they will be suspended. In the water, it will not adhere to the pipe wall to prevent the formation of scale. Due to the precipitation of calcium and magnesium plasma from the water, the water returns to a highly soluble state. Water itself is a highly soluble liquid, but it will become saturated due to the absorption of other substances. When the water returned to a highly soluble state flows through the scaled pipes, it will be able to Scale dissolves and absorbs, and is discharged when draining. Therefore, in addition to preventing scale formation, this product can also effectively remove old scale.
