Concrete cooling towers have been ruling the roost since a long time. Many of them are still in operation in different regions of the world due to their intrinsic efficiency and durability. Every country has its own penchant for cooling tower material. A concrete cooling tower is made out of 100 percent material that is corrosion free. This is because the manufacturers agree on the fact that even the best of the stainless steel used in the cooling tower has been known to get oxidized, turns brown, and requires regular cleaning. If the walls of the FRP cooling tower are doubled, its life span may be increased to match that made of concrete. When manufactured by a company of repute and maintained properly, concrete cooling towers emerge as clear winners among all material. They can be expected to last for over 50 years without suffering break-downs.
Concrete cooling towers create a lower level of noise than conventional FRP towers. This occurs due to the natural properties of concrete. Towers made of concrete are usually constructed as an ordinary part of the architectural design and, thus, have a pleasing appeal. The towers turn out to be considerably more flexible, where space is concerned. The client can allocate separate area where the concrete tower manufacturer can erect the tower as a substitute for having them installed in separate plant rooms which might be tight on space. The client is only required to work alongside the architect and have the concrete cooling towers constructed in tandem with the other structures of the plant.
Concrete cooling towers are mostly found in industries of petro-chemicals, energy, crude oil processing, and metallurgy. The fundamental parts of the tower comprise of its concrete skeleton, diffuser, axial ventilator, eliminators, spraying jets, and fillers. A thorough understanding of the working of the cooling tower is needed in order to the construct them. The structure, as well as, the foundation has to be designed so that they can withstand vibrations from the fan, motor, gear-box, etc, strong winds, and seismic movements over a long span of time. Continuous contact with water makes these towers susceptible to attacks by fungi, algae, decay, and deposits left by water of inferior quality.
