The water stored in a commercial cooling tower can also contribute to other potential problems such as bacterial contamination and the accumulation of lime deposits. Similar biological accumulations on a scale can affect the heat transfer to the surface of your tower and reduce your cooling efficiency. In addition, high pressure and water consumption due to lime deposits and other clogging can lead to higher temperatures in your commercial cooling towers.
Treating a cooling tower to supply water for circulation and drainage can lead to several problems, the four most common being corrosion, pollution and biological growth. All of this can negatively affect the success and efficiency of your cooling towers, impact the energy and water consumption of the tower and increase the cost of long-term operation of the tower. In addition, significant contamination of the system can occur in a cooling system, caused by suspended matter produced by the water washing of the cooling tower and the process of leaks that promote microbial activity.
This exchange takes place by forcing the air to cool the fans and the water to come into contact with each other. If the water fails to pass through the filling structure, the air does not cool down. This not only causes unreliable operation, but also endangers the safety and efficiency of the entire cooling process.
The usual pipes and water loops used to heat cooling towers in buildings can be switched off, emptied, made winterproof to prevent freezing and damage to the heat supply, or otherwise (e.g. By separate boilers). Some cooling towers use the evaporation of water to remove and process heat from the coolant (moist light bulbs) and air temperature (in closed cooling towers and dry cooling towers relying on air-cooled working fluid and dry light bulbs, air temperature can be used as a radiator). Flammable gases and combustible liquids can be mixed with the water used for cooling, transported in cooling water recirculation pipes and released into the tower distribution system where they can ignite.
During maintenance of water treatment, cooling systems and cooling towers, the heat exchange surfaces are cleaned in such a way that your commercial HVAC system functions safely and efficiently. Proper treatment of your cooling tower includes water control, occasional cleaning of tower surfaces, lubrication and realignment of moving elements and machinery, and compliance with local regulations and developments related to cooling tower safety. Companies using a step-up plate cooling tower must develop proactive, ongoing maintenance procedures to align efficient waste management technologies, effective water testing and treatment techniques and elemental alignment to ensure safe, healthy, and efficient operation.
Best practices require the wearing of respirators, gloves and protective clothing to prevent exposure to bacteria like legionella. Cooling water may not look dirty or dangerous, but just because it is clear does not mean that it is clean and bacteria-free or that the cooling tower parts aren’t housing it.
Legionella is one of the most pressing problems in cooling towers because it can pose a threat to human health, and many of your most common maintenance tasks involve the control of potential bacteria through water treatment and testing. The decision not to treat the cooling tower water for corrosion-related contamination can be costly and dangerous. Improper maintenance of equipment and appliances, including cooling towers and water heating systems, can result in thousands of dollars in repairs and the loss of efficient energy.
