Cooling Tower Management And Maintenance – Cooling towers are a prominent feature of the landscape of many industrialized countries across the world. Although commonly associated with large factories, nuclear plants, and power stations, they are actually present in most business properties, including office buildings, and can range in size from small roof-top fixings to giant structures exceeding 200 meters.
But why are they so important to commercial properties? In essence, they help maintain the temperature in a work environment. Cooling systems ensure that excess heat escapes from the workplace, helping to maximize productivity.
Cooling Tower Management And Maintenance –
How do cooling towers work?
These towers can work in two ways: by evaporation or by using air. The latter method is an open circuit system, in which the water is pumped to the top of the cooling tower and redirected through an artery that helps to transform the water into drops. These drops are exposed to an air passage that cools them as it passes. This cooled air is collected at the bottom of the structure, where it is transmitted to the production process.
On the other hand, the evaporation method exposes the water to the external atmosphere to allow the natural evaporation process to take place. The greater the temperature difference between water and outside air, the faster the cooling effect. This type of cooling system is more suitable for dry climates than humid or tropical environments and can form a closed or open circuit.
How to Keep a Safe Cooling Tower
When determining which waste management and maintenance technology will be used, it is important to first determine where the waste comes from. If the source of waste is water (for example, sediments, lakes or river algae or water with a high content of dissolved solids), water filtration in combination with a good water treatment program is usually the best solution and this will protect the chiller and heat exchanger from escaping and getting dirty.
If, on the other hand, the source of waste is air-related (poplar seeds, insects, leaves, pine needles, paper, birds and droppings, harvest straw, construction debris, etc.), the water filtration systems do not prevent debris in the cooling tower (especially the filling).
For problems with air debris, the best solution is to prevent waste from entering the system using the air intake filter technology that filters the air when it enters the system. Air intake filtering in combination with a good water treatment program is extremely effective in stopping the type of debris that clogs up filters, valves, filters, refrigerators, and heat exchangers – in short, air intake filtering effectively protects the entire system. In extreme cases where water and air residues are problematic, air-water filtration and water filtration in combination with a good water treatment program may be necessary to keep the cooling tower safe and functionally efficient.
It is recommended for the cooling tower to be checked regularly and immediate action was taken in case of any problems found. These will help to reduce more damage to the cooling tower as well as maintain the safety of all the clients.
Regardless of the procedures adopted to maintain the cooling towers, personal safety measures must be an integral part of the maintenance methods. Good practices necessitate workers to wear protective clothing, respirators, and gloves to reduce exposure to bacteria, such as Legionella. Its good to remember that cooling water may be dangerous even if it does not look dirty- just because the water is transparent does not mean it is bacteria-free or clean – Each cooling tower system can hold bacteria. Always take precautionary measures because, unless the water is routinely tested for Legionella and other bacteria, the bacteria will never announce their presence until it is too late.
Back up plans and disaster recovery cooling systems
Both air cooling and evaporation depend on several cooling towers in operation. Even in small commercial properties, cooling towers generally work in pairs, with each structure independent of the other. This ensures that if one tower fails, the other will be able to provide backup.
In some cases, such as sudden heat waves or prolonged periods of hot weather, a company’s existing infrastructure is insufficient to maintain a productive temperature. In such cases, contractors should consider renting cooling towers to enlarge the capacity and make sure that the work environment temperature is not interrupted.
It is also important for companies to have a comprehensive disaster recovery plan in case an existing system is completely damaged due to technical problems or a major natural event. When looking for an emergency cooling tower service provider, think carefully about the benefits they offer. Indispensable benefits include 24-hour availability, high capacity cooling tower towers, and long experience in the industry.
