Did you know that the world’s tallest cooling tower is the 202 metres tall cooling tower of Kalisindh Thermal Power Plant in Jhalawar, Rajasthan, India? Overall, cooling towers are very important pieces of machinery, used in a variety of different mechanical and industrial applications. If you are wondering what are cooling towers, cooling towers can essentially be described as systems used to cool pieces of machinery. Common applications for cooling towers include cooling the circulating water used in oil refineries, petrochemical and other chemical plants, thermal power stations and HVAC systems for cooling buildings.
However, when it comes to industrial cooling towers it is important to note that there are several different types of industrial cooling towers. For example, wet cooling towers or open circuit cooling towers operate on the principle of evaporative cooling. These kind of industrial cooling towers use the evaporation of water to remove process heat and cool the working fluid to near the wet bulb air temperature. You might also want to look into fluid coolers, also known as closed circuit cooling towers. These kinds of towers are hybrids that pass the working fluid through a tube bundle, upon which clean water is sprayed and a fan induced draft applied. The resulting heat transfer performance is much closer to that of a wet cooling tower. However, it does provide some of the advantages of dry cooler, protecting the working fluid from environmental exposure and contamination. Overall, there are many other types of industrial cooling towers. Therefore, it make take a bit of research to figure out which type of industrial cooling tower is best for a specific situation.
