Water is the synonym of life and is used in every industry for various purposes. Apart from being a part of the basic manufacturing process, water is also an integral part of the cooling process in the domestic and commercial spaces to cool down the elevating temperature. Cooling towers were in use for a long time but it had numerous disadvantages. It offered cooling effect in exchange for a huge noise that was capable of affecting the regular activity of the daily life. There are numerous sizes of water cooling towers in India and in order to get the most of it, you must select a suitable size. Only a size and specification compatible cooling tower will be able to produce the desired result.
Why Cooling Tower? In the industrial plants like nuclear, thermal power, petrochemical, petroleum refineries, HVAC systems, food processing, etc. a huge amount of heat is produced that need controlling in order to avoid any catastrophe. Cooling towers can eliminate the heat generated in a reliable, silent, and cost-effective way, which must be chosen smartly in order to get the effective result. Cooling Tower Size and Importance The size of the cooling towers matters the most when the efficiency is concerned. If a cooling tower with smaller than the required size is installed in a plant, it will not be able to cool the process efficiently. This will demand a huge expense for remodeling of the tower. On the other hand, it might also damage the different machinery products due to less cooling effect. Benefits of Cooling Towers Cooling towers are not only used to cater the cooling needs, but also to offer numerous other benefits like:
Cooling towers are an essential attachment of any industry that saves almost all the machinery and manpower from any heat-related mishap. It not only cools the heat of the system, but also saves the process from getting affected due to the natural or chemical agents. In order to get the best results of a cooling tower, it is suggested to get the site inspected by an expert, who will be able to specify the exact size and functionality of the tower in the most cost-effective, noise-less, and fruitful manner.

Cooling towers play crucial role in many chemical factories. The major task of cooling tower is to remove heat and release it into atmosphere. Cooling tower manufacturers design inexpensive models, which are used for removing low-grade heat from cooling water. They use make-up water to replenish water lost to evaporation. Manufacturers are intending many models. Cooling towers are categorized into two designs – natural draft and mechanical draft. Natural draft models have large fans that force or suck air through circulated water. The water falls down on the fill surface that helps in increasing contact time between the air and water through which heat transfer between the two gets maximize. Cooling rates of mechanical draft tower relies on their fan diameter and operation speed. The mechanical draft tower is more used by industries and so we will talk about it. You can get mechanical draft towers in following airflow arrangements from manufacturers –
Frame and casing – Most cooling towers are designed with structural frames that support the casings, fans, motors, and other components. Fill – In most of the models, they use fills that are made of wood or plastic to initiate heat transfer by maximizing air contact and water. Manufacturers use either splash type of fill or film type of fill in the cooling tower. Cold water basin – It is located at or near the tower bottom. Cold water basin receives the cooled water that flows down across the fill and tower. Drift eliminators – These drift eliminators catch water droplets entrapped inside the air stream that would be lost to the environment. Louvers – Cross flow cooling towers contain inlet louvers. These components are used to equalize air flow inside the fill and retain the water within the tower. There are many counter flow cooling towers that don’t need louvers. Air Inlet – This is the entry point for the air. Air enters to the tower through air inlet. Nozzles – Nozzles offer water sprays to wet the fill. These parts can be fixed in place and have square or round spray patterns or can be fixed to the rotating assembly as found in some circular cross-section towers. Cooling tower manufacturers design these components with premium grade raw materials for best and efficient performance. If you have any query, write to experts and wait for their response.

However, you have to perform it to ensure optimized thermal performance and to revoke the growth of biofilm and harmful bacteria, including legionella. Manufacturers always provide proper guidelines to their customers about cleaning and maintenance of the cooling towers. It is suggested cooling towers and evaporative condensers should be cleaned and disinfected at least once a year. If the bacterial growth is high, cleaning should be performed more frequently. Though cleaning of cooling tower is not a substitute for water treatment, but it is a part of entire programme for effective bacteriological control. How cleaning is done?
Here is the step-by-step guide that manufacturers and experts perform to clean and disinfect the cooling tower inside surface.
Why it is important to perform these steps? Cleaning and disinfection of the cooling tower unit is important to prevent the growth of bacteria legionella. The process is performed in accordance with regulatory or site specific safety and health requirements. Each maintenance visit includes a detailed report that tells the condition of the equipment and suggestions for further refurbishment and repair. For any assistance regarding cooling tower maintenance and cleaning, you should always call professionals. They are experienced and qualified and can provide best services at competitive prices. You must remember to call them at least once a year to perform cleaning and disinfecting of the unit.

Suppliers of cooling towers India introduce new cooling method that people can use for supercomputers. The system built by the experts is named as thermosyphon cooler hybrid system that cools like a refrigerator without the expense and energy requirements of a compressor. At present, several data centers are using water to eliminate waste heat from servers. The warmed water is sent to cooling towers through pipe, where a separate water stream is turned to mist and evaporates. Just like when our body temperature rises, it sweats and this sweat evaporates from the body. This process removes heat from the piped water, which returns to cool down the installation. However, the large-scale replenishment of the evaporated water is required throughout the world to eliminate heat from the increasing number of data centers, which are day-by-day increasing in size as more users store data into the cloud. Earlier it was a mere joke for the people that water can directly cool supercomputers. They believed that they need air for the same. But this new approach of using water to directly cool the temperature of supercomputers really worked. So now most data centers use water to cool themselves and in future, refrigerant cooling coming in for half the data centers running in the US. The prototype technique uses a liquid refrigerant and not water to eliminate heat. The system operates like-
Warm water is pumped inside the closed system into proximity with another system that has its own refrigerant. This refrigerant absorbs heat from the water, so that the cooled water can re-circulate to cool the system again. Simultaneously, heated refrigerant vaporizes and rises within its closed system to release heat in the atmosphere. When heat is eliminated from the refrigerant, it condenses and sinks to soak more heat, and this cycle repeats. There is no water loss because a cooling tower relies on evaporation. Experts don’t need to add chemicals like biocides and this save their expenses. This prototype system doesn’t use a compressor, which would incur more costs. The system uses refrigerant that is phase-changing and needs outside air only to absorb the heat. For more details on the system, contact as suppliers of cooling towers India. You can even make comments below. Poor maintenance of equipment can make people sick. The best cleaning efforts and proper maintenance of cooling towers are necessary to avoid bacteria growth inside equipment. One of the popular bacteria is Legionella that is taken seriously to take various lives and it may sick people badly.
Manufacturers intend induced cooling towers with specialized technology that let these towers to perform as heat exchangers in which air and water are brought into direct contact with each other to lower the temperature of water. An evaporative cooling tower cools down water to approx 85 degrees Fahrenheit and can reach at minimum level of 65 degrees Fahrenheit. You can think about evaporative cooling tower systems for cooling large amount of water. It has a fan motor that uses minimum energy and efficient methods to cool the water. How It Works? These towers allow evaporation of little amount of water. The moving air steam will offer significant cooling to the remaining water stream. The evaporating water absorbs the heat from remaining water, which helps in lowering the temperature of the tower. The air should have ability to absorb water. Air will absorb lesser water and less cooling effect will be done when the level of humidity is higher. |
