Industrial Cooling Tower
Industrial cooling towers can be used to remove heat from various sources such as machinery or heated process material. The primary use of large, industrial cooling towers is to remove the heat absorbed in the circulating systems used in power plants, petroleum refineries, petrochemical plants, natural gas processing plants, food processing plants, semi-conductor plants, and for other industrial facilities such as in condensers of distillation columns, for cooling liquid in crystallization, etc
What is Cooling Tower
Cooling towers are a special type of heat exchanger that allows water and air to come in contact with each other to lower the temperature of the hot water. During the cooling tower working process, small volumes of water evaporate, lowering the temperature of the water that’s being circulated throughout the cooling tower.
In a short summary, the purpose of a cooling tower is to cool down water that gets heated up by industrial equipment and processes. Water comes in the cooling tower hot (from industrial process) and goes out of the cooling tower cold (back into the industrial process). Here we discover cooling tower functions and inner working of cooling towers for different applications.
How do Cooling Tower Works
ooling towers are a special type of heat exchanger that allows water and air to come in contact with each other to lower the temperature of the hot water. During this process, small volumes of water evaporate, lowering the temperature of the water that’s being circulated throughout the cooling tower. In a short summary, a cooling tower cools down water that gets over heated by industrial equipment and processes.
The hot water is usually caused by air conditioning condensers or other industrial processes. That water is pumped through pipes directly into the cooling tower. Cooling tower nozzles are used to spray the water onto to the “fill media”, which slows the water flow down and exposes the maximum amount of water surface area possible for the best air-water contact. The water is exposed to air as it flows throughout the cooling tower. The air is being pulled by an motor-driven electric “cooling tower fan”.
When the air and water come together, a small volume of water evaporates, creating an action of cooling. The colder water gets pumped back to the process/equipment that absorbs heat or the condenser. It repeats the loop over and over again to constantly cool down the heated equipment or condensers.

Types of Cooling Tower Systems
Cooling towers are usually designed for specific purposes. Not all cooling towers work for all applications or industrial processes. Here we help you understand the various types of cooling towers, there advantages/disadvantages and determine which cooling tower type is right for your industrial process. Check out the cooling tower list and parts list that provides an overview of cooling tower types to help you figure out which tower is right for your industrial application and what replacement parts you might need.

- Induced Draft Cross Flow
- Forced Draft
- Natural Draft
Operation Considerations of cooling tower
Cooling tower mass balance gives an indication about make-up water requirement in system. Cooling Tower Makeup is required due to water losses resulting from Drift, Evaporation & Blowdown.
Water make-up (M ) = Total water losses = Drift Losses ( D) + Evaporation Losses (E ) + Blow down Losses (B)
M = D + E + B
M = Make up water Requirement in m3/hr
D = Drift Loss in m3/hr
E = Evaporation Loss in m3/hr
B = Blow Down in m3/hr
