2.Quality and Reliability:
The quality and reliability of a cooling tower should never be overlooked. Cooling towers are long-term investments, and their durability and reliability are paramount. Assessing the material quality, manufacturing processes, and reliability of components is essential. Additionally, researching the reputation and experience of the manufacturer is advisable. Choosing a high-quality cooling tower from a reliable manufacturer reduces the risk of failures, extends equipment lifespan, and minimizes maintenance and replacement costs.

3.Maintenance and Upkeep:
Maintenance and upkeep are important considerations when purchasing a cooling tower. Regular cleaning, repairs, and preventive maintenance are necessary to ensure optimal performance. Understanding the maintenance requirements, workload, and associated costs is crucial. Seeking advice from the manufacturer or other users regarding maintenance plans and best practices is recommended. Opting for a cooling tower with user-friendly designs and comprehensive maintenance support can lower maintenance costs, downtime, and keep the equipment operating at its best.

4.Energy Efficiency and Environmental Impact:
Energy efficiency and environmental impact are increasingly important considerations for buyers. Inquiring about energy consumption, energy-saving measures, emission standards, and sustainability aspects of the cooling tower is essential. Choosing a cooling tower that meets energy efficiency standards not only reduces operational costs but also minimizes environmental footprint. Prioritizing energy-efficient and environmentally friendly cooling towers aligns with sustainable practices and demonstrates social responsibility.

5.Cost and Price:
Cost and price are significant factors when purchasing a cooling tower. Evaluating the price, operational costs, maintenance expenses, and making comparisons with competing products is necessary. It's important to strike a balance between performance, quality, and affordability. While high-quality and reliable cooling towers may have a higher initial investment, they may offer lower overall costs in the long run by requiring less frequent repairs and component replacements.

When purchasing a cooling tower, a comprehensive approach that considers efficiency, performance, quality, maintenance, energy efficiency, and cost is crucial. Engaging in dialogue and seeking advice from manufacturers, suppliers, and other users is recommended. Only by thoroughly understanding and weighing all these factors, can an informed decision be made. By selecting the most suitable cooling tower that aligns with specific needs and industry requirements, one can ensure efficient and reliable operation, resulting in long-term benefits for their business.
Cooling towers are widely used by many industries to deal with excess heat that is produced by manufacturing processes and other industrial activities. Put simply, a cooling tower is a device that works to lower the temperature of a water stream. This is done so that the hot water in circulation is cooled enough to be used again in the boiler. Most cooling towers rely on using evaporation to lower the temperature of the circulating water.

Cooling towers can differ significantly based on size, build, materials used and mechanisms of operation. Understanding the differences between various cooling tower types is essential for choosing the right one for your needs.
Below we answer some important questions you might wish to ask before deciding which cooling tower would be best for you.
How is airflow generated in cooling towers?
Cooling towers operate by using constant and reliable airflow which can be produced and maintained in a variety of ways.
A cooling tower can operate using:
- Natural draft. Such cooling towers are constructed in ways that utilise the design of the tower to move the air up by using fans.
- Mechanical draft. These rely on a centrifugal fan or propeller pulling the air from the bottom. The fan is usually placed at the top of the tower and blows warm air out of the tower while also sucking in the cool and dry outside air.
Natural draft cooling towers – best uses
Cooling towers that use natural airflow are usually located outside, which allows them to release warm air directly into the environment. This is why these are normally used in industrial settings – such as power plants located near the load centres and away from the fuel source point. In such cases, using a natural draft cooling tower allows saving on the costs of power that would otherwise be needed to operate cooling fans.
Mechanical draft cooling towers – best uses
These cooling towers tend to be significantly smaller than natural draft towers, which makes them suitable for use inside the plants and other facilities. As you are also able to monitor and control the speed of the cooling fans, mechanical draft towers are preferred where capability control is important.
Also, as these towers use power to operate the cooling fans, they are widely used where cheaper power is accessible – for example, at power plants located close to the fuel source.
Climate conditions also need to be taken into consideration, as natural draft towers are not well suited for areas with long, hot, dry summers. In such cases, the air density difference that is needed for an efficient operation of natural draft towers is hard to achieve, so mechanical draft towers are preferred.
How is heat transferred in cooling towers?
Cooling towers can use dry heat or wet heat transfer methods.
Dry cooling towers – best uses
A dry cooling tower simply transfers heat through a surface separating hot water from the air. As no water evaporation occurs, no additional water is needed. Hot water from the condenser just keeps circulating through the tubes exposed to ambient air that absorbs its heat, cooling it down. Sometimes, fans are installed to improve the airflow.
As this type of heat transfer is quite inefficient and involves high energy usage, it is reserved for situations where water supply is limited – or where regulations specifically disallow any plume.
Wet cooling towers – best uses
Also known as open circuit cooling towers, these towers use the natural process of water evaporation as a cooling method. What is emitted as a result is just heated water droplets that cause no harm to the environment.
Wet cooling towers are very popular because of their cost-efficiency and use of renewable resources (water). They are most likely to be your first choice if you have access to an adequate water supply.
How are cooling towers constructed?
Depending on your needs, you can have your cooling tower field erected – or you may decide to go for a package type tower.
Field erected cooling towers – best uses
These are large non-transportable towers that weigh over 1,500 tonnes per cell and have a significant cooling capacity. Because of their size, they need to be assembled on site. These towers are also often built to custom specifications.
Power plants, oil refineries, petroleum sites and steel processing plants often use field erected cooling towers.
Package type cooling towers – best uses
These towers are smaller in size than field erected towers – so they are assembled at a factory and then can be easily transported to the usage site.
Facilities with comparatively low heat rejection requirements – such as office buildings, hospitals and shopping centres – normally use cooling towers of this type.
