Industrial revolution was the starting point for the need of industrial appliances. Electrical products, pressure equipment, manufacturing machines are a few to name. One most common industrial appliance today is cooling tower. It is an inexpensive way of removing heat to the atmosphere through cooling water. History of Cooling Tower Cooling Tower has its history way back in the 19th and 20th century. It is an innovative concept originated out of the development of condenser used in steam engine. A condenser uses cool water to condense the steam coming out of pistons and turbines. However, the mechanism requires considerable amount of cool water supply. To overcome the challenging situation, engineers began to introduce several cooling water recycling methods effective in those areas where there was limited supply of water. During the course of invention and innovation, they came up with quite a few designs. And, of the many outputs, cooling tower of today became the final choice of all. Cooling Towers Today Initially, the cooling tower used to be made up of wood only. But today, the product line includes towers made up of Fiber Reinforced Plastic (FRP) and Reinforced Cement Concrete (RCC). The manufacturing companies use high-end technology and certified techniques to construct each part of the equipment. They have experienced engineers to offer devices of better product life. Today, a cooling tower catalogue includes good number of varieties of industry standards. Some of the most popular forms of towers are mentioned below: • FRP (Rectangle, Round and Square) FRP cooling tower is gaining prominence in the present industrial scenario. The compact designs and light weight features allows easy installation on roof-top or any other specific location as per requirement. Engineers believe that FRP towers give optimum level of performance and help end-users to save considerable power. The kind of device can withstand high velocities and natural shocks without any complications. • Wooden Towers It is manufactured out of the chemically treated timber wood. As of now, the usability of wooden cooling system is facing tough competition over FRP products. Yet, there are good number of steel mills and petrochemical mills using the system as heat removal device. • Concrete Constructed of RCC outer structure, it is a permanent cooling solution for industries. The tower is just an example of the 19th century condenser where water requirement is very high. Concrete cooling system is largely used in fertilizer plants and power stations. • Parabolic Parabolic Cooling Tower has massive structural strength and has high resistance to wind loading. This kind of tower is mostly constructed to perform heavy heat duties in vast industrial areas. The development in cooling mechanism has led HVAC industry to go a long way. Industries have wide options to make their best investment. However, it is always advisable to make thorough research before making any purchasing decision.
