Many components and elements function together for creating an efficient, operable cooling tower. Most of these components may be required to be replaced or repaired in the life-time of a cooling tower.
The following is a closer look at some such components like gearboxes, nozzles, fill media, fans, cooling tower drift eliminators, etc.
1. Gear Boxes
These are found in several different reduction styles and rates for supporting the variable fan speeds and strengths in cooling towers. The producers of cooling towers usually permit clients to buy fresh gearboxes or use the services of skilled experts to renew or restore a gearbox with OEM (Original Equipment Manufacturer) parts.
2. Drift Eliminators/Reducers
Cooling tower drift eliminators are vital parts of cooling towers that function to get rid of water droplets in the air and recycle the moisture for operational processes. They do this by forcing moist air to move abruptly in another direction, by separating the moisture from the air and redirecting it to another part of the cooling tower.
3. Fill Media
This is a vital component of a cooling tower. The majority of the latest cooling towers efficiently fill media made of plastic for maximum evaporation of water. Water is disseminated via the fill, that flattens away to form a narrow film over a big surface area. Such a procedure enables rapid evaporation of excess heat and moisture.
Fill media are selected based on levels of TSS (Total Suspended Solids), water composition, sensitivity to contamination, and intended use. Types of such media include Splash style and Film style as well as counterflow and crossflow.
These are found mostly in cooling towers of crossflow that exploit the gravitational pull for distributing water. In such systems, there is the lifting of water to reservoirs on top of fill media. The water is then pulled by gravity via fill media via nozzles at the base of reservoirs.
5. Tower Fans
They serve the function of pushing or forcing air, all through the cooling tower. Such fans need to be strong enough to withstand the corrosive atmosphere in which they work. Some models are noisy, while quieter models are also available. Such equipment is found in all cooling towers of the mechanical draft type, including crossflow and counterflow towers.
They are custom made for transferring energy from the outflow shaft of the engine of the cooling tower into the gear reducer’s intake shaft. Such a process results in creating a rotating power which turns the blades of the fan. Driveshafts are found in lengths ranging from 2 feet in small, air-conditioning towers to over 20 ft. in industrial towers of heavy-duty. They are required to have the quality of rustproofing since they function in corrosive environments.
7. Electric Float Valves
These are components needing low maintenance. They maintain the functionality of the cooling tower for a long time. In the majority of cases, kits for electric float valves may contain valves, arms and floats to accommodate a variety of tasks.
8. Air Intake Louvers
Such components stop the rays of the sun from impacting the reservoir of water. This prevents the formation of mould and algae and reduces expenses on chemical treatment. They also stop the water from dashing out of reservoirs. This benefit lowers the quantum of chemicals and water required while rendering the reservoir easier for accessing and removing. Louvers in counterflow towers need proper care, or they may develop scaling.
These are some of the main components of a cooling tower.
