The summer ends and the cooling equipment stops suffering, or at least the eyes of the personnel of production and maintenance of the various industrial plants of the country, stop worrying about them, however despite entering the season of lower environmental temperatures , it is ideal to be able to program the corresponding maintenance for the cooling equipment, such as cooling towers, evaporative condensers, chillers, etc.
Although in many companies there is no policy of preventive maintenance, but rather corrective, it is necessary to take into account that given the conditions in which these equipment operate, it is important to consider a biannual or at least annual maintenance so that their efficiency in the exchange thermal is optimal, and depending on each equipment and treatments received by the water, it is recommended up to quarterly maintenance. Because the cooling towers operate with air extracted from the environment, it is common to carry particulate matter, dirt, paper, bags, insects, etc., which forms a mud that solidifies and ends up clogging the distribution nozzles. of water, fillers or panels, pipes, pumps and valves.
Also the thermodynamic process of heat transfer from the cooling tower to the environment,
It is carried out by evaporation which generates mineral salts that accumulate in all the pieces described above. Although it is true that water treatments are used to reduce the harmful effects of salt scaling and other components, this does not solve the underlying problem,
that the water finally receives more chemical components that sooner or later must precipitate and must be filtered.
Faced with these problems, the temperature changes are added, which when they are very drastic, the evaporative fillings of the cooling towers tend to crystallize.
Therefore, it is highly recommended to clean the fillings and the tower in general, since this could generate savings in maintenance budgets, in the long term. The periodic cleaning of the cooling towers and their panels, prevents companies from having to replace their fillings in the short term, since when the panels are well maintained they can have a useful life greater than 10 years, otherwise and depending on of the processes, they can last 3 months or a year. A company that only performs water treatment will have fillings that can last without problems for more than 4 years, but if from time to time, the total water of the tower is replaced by a new one and if its fillings are washed, it can easily double the useful life of your fillings.
