Good to Know
What is a cooling tower?
A cooling tower is a piece of equipment that dissipates excess heat from industrial processes or power plants into the environment. This is achieved through evaporative cooling, in which water comes into contact with air and the heat is released into the atmosphere in the form of steam. Cooling towers are used in various sectors, such as power generation, the chemical industry, and building air conditioning.

Cooling Towers: Questions and Answers
How does a cooling tower work?
A cooling tower dissipates excess waste heat into the environment if it cannot be utilized (e.g., for district heating). Thermal power plants, in particular, are often equipped with a cooling tower.
An overview of how a cooling tower works:
| PROCESS | Description of How It Works | Advantages | Disadvantages |
|---|---|---|---|
| Waste Heat Removal | Cools excess waste heat and dissipates it into the environment. | Effective for dissipating excess heat | No direct use of the waste heat |
| Evaporative cooling | Water is distributed over the fill media via nozzles and transfers heat to the air. | High efficiency in heat dissipation | Relatively high water consumption |
| Fan assistance | Fans generate an artificial airflow to enhance heat removal. | Enhanced cooling capacity | Increases energy consumption |
| Water losses | Evaporation of water leads to losses that must be replenished in the system. | Need to replenish water | Water losses due to evaporation |
| Evaporation process | Water evaporation increases the cooling tower’s efficiency. The vapor condenses above the tower. | No vapor forms in the surrounding area; instead, “mists” are produced | Potentially visible wisps of vapor |
What types of cooling systems are used in cooling towers?
Wet cooling
Water evaporates, and heat is transferred to the rising air.
Advantages:
- High efficiency
- Suitable for situations with high thermal loads
Disadvantages:
- High water consumption
- Mist formation
- Risk of Legionella
Direct Dry Cooling
Fans cool the medium in finned tubes using ambient air.
Advantages:
- No steam formation
- No risk of germ spread
Disadvantages:
- Lower efficiency
- Requires a lot of space
- High investment costs
Hybrid / Adiabatic Cooling
A combination of wet and dry cooling.
Advantages:
- Low water consumption
- Less steam formation
- High efficiency
Disadvantages:
- Higher investment costs
- Energy consumption due to fans
What materials are cooling towers made of?
Cooling towers can be made from various materials, depending on the type of cooling tower and the requirements for maintenance, efficiency, and cost. Generally, a distinction must be made between the two types of cooling towers - natural draft cooling towers and mechanical draft cooling towers:
- Due to their size, natural draft cooling towers are constructed from reinforced concrete and wood. Smaller cooling towers of this type may also consist of a wood or steel structure clad with sheet metal.
- Mechanical draft cooling towers are made of either sheet steel or glass-fiber reinforced plastic (GRP). When it comes to sheet steel, a further distinction is made between stainless steel and coated thin-gauge sheet metal.
| MATERIAL | ADVANTAGES | DRAWBACKS |
|---|---|---|
| Stainless steel |
|
|
| Coated thin sheet metal |
|
|
| Glass-fiber reinforced plastic (GRP) |

Cooling towers are primarily used in thermal power plants to dissipate excess waste heat and create the temperature difference needed for electricity generation. They play an important role in reconditioning exhaust steam from turbines and can cool up to 100,000 m³ of water per hour.
In addition to power plants, cooling towers are also used in the chemical and steel industries, as well as in shopping centers and sports arenas for cooling purposes.
The cost of a cooling tower depends on its cooling capacity, design (open or closed), and technology (e.g., EC fans). Other factors, such as water consumption, height, and additional features like silencers, also play a role. A cooling tower with higher capacity and special requirements, such as hybrid technology, is more expensive than standard models.
Operating costs mainly include energy consumption for fans and pumps, water consumption, and maintenance costs. Hybrid cooling towers tend to have lower operating costs due to their lower water consumption, but they have higher energy consumption because of the additional fans.
A cooling tower should be serviced at least once a year to maintain efficiency and prevent contamination. More frequent servicing is recommended in cases of heavy use or special requirements (such as Legionella prevention).
Legionella can be prevented through regular water treatment, chemical treatment, and cooling tower maintenance. A well-maintained water distribution system and controlled temperature help minimize Legionella growth.
VDI 2047 is a guideline for water treatment and hygiene in cooling towers. It establishes standards to ensure safe operation and control microorganisms.
We offer comprehensive services for cooling towers, including installation, maintenance, repair, and hygiene solutions. This also includes testing for Legionella and optimizing cooling performance to ensure a long service life and high efficiency for your cooling towers. Upon request, we can design and build a cooling tower exactly according to your specifications - custom-made and tailored to your needs.
A well-maintained cooling tower can last 20 to 30 years. However, its service life depends on various factors, such as its design, operating conditions, and regular maintenance. Regular maintenance and timely repairs extend the cooling tower’s service life and optimize its efficiency.
A cooling tower differs from other cooling systems in its ability to efficiently transfer excess heat to the environment through evaporation. Compared to air conditioners or air coolers, which often rely on artificial cooling, the cooling tower uses a natural process (evaporation), making it particularly energy-efficient and environmentally friendly.
