What are Industrial Cooling Towers

industrial cooling towers are tall, open-topped, cylindrical concrete towers that are used for cooling water or condensing steam from an industrial process. They are an important factor of many chemical plants. The basic task of a cooling tower is to transfer heat out into the atmosphere. They are an inexpensive way of removing low-grade heat from cooling water. In addition, they are used to cool circulating water that is used in oil refineries, thermal power stations, chemical plants and HVAC systems to cool buildings.

How do they work?


The first step in the tower process is to replace leaked and evaporated water from the cooling tower; water that is drawn from city water, raw water well water or other surface water source. At this point in the process, treatment may or may not be needed. Then, the cooling tower water is run through some type of filtration to remove suspended particles. If there is a high amount of hardness found in the makeup water, treatment may be given to remove the hardness.

The next step is a treatment process to remove the hardness. A softening resin may be used instead of lime. The next step is the use of chemicals such as corrosion inhibitors, biocides and scale inhibitors. In addition, if the cooling tower water is recirculated throughout the system, a side-stream filtration will be used to remove contaminants. The last part of the treatment is the blowdown or bleed from the tower.


Why are towers important?


cooling towers are important because they reject and push out heat into the atmosphere. In addition, the make-up water source is used to replenish water that is lost to evaporation. Then, the water comes out the cooling tower and is sent back to the exchangers for further cooling. Cooling towers are an inexpensive and dependable way to remove low-grade heat from cooling water. Other important factors are revitalizing equipment, a reduction in maintenance needed for clean water and an improvement in microbiological control. Most importantly, these towers prevent contaminants in the water that can cause harmful, environmental waterside problems.


To conclude, industrial cooling towers are tall, open-topped, cylindrical concrete towers that are used for cooling water or condensing steam from an industrial process. They are an important factor of many chemical plants and oil refineries. Find more information about industrial towers from a cooling tower company today.
