Good to Know: What Is a Cooling Tower?
A cooling tower is a technical system designed to dissipate excess heat from industrial processes or power plants into the surrounding environment. It operates through evaporative cooling, where water comes into contact with air and releases heat in the form of vapour into the atmosphere. Cooling towers are used across a wide range of applications, including power generation, the chemical industry, and building climate control.
Cooling Towers: Stainless Steel Cooling Technology
At MULTI Kühlsysteme GmbH, we provide:
- Cooling towers that reduce water temperature through the natural principle of evaporative contact with air
- Outstanding performance ratings in accordance with VDI 2047 and CTI standards, reflecting the ratio of heat dissipation to auxiliary energy input — also known as the Energy Efficiency Ratio (EER)
- Comprehensive cooling water hygiene concepts to maintain consistently high system efficiency
Our MC series cooling towers are equipped with highly efficient EC fan technology.
MULTI Kühlsysteme GmbH is your specialist cooling tower supplier, providing cooling towers, heat exchangers, and cooling water hygiene solutions. We deliver highly efficient systems that cool water by harnessing the natural principle of evaporative air contact.
As a dedicated cooling tower manufacturer, we are on hand to support you — whether locally, nationwide, or across the globe.
A cooling tower dissipates excess waste heat into the environment if it cannot be used (e.g., for district heating). Thermal power plants in particular are often equipped with cooling towers.
An overview of how a cooling tower works:
| Process | Description of how it works | Advantages and disadvantages |
| Waste heat dissipation | Cools excess waste heat and releases it into the environment. | ✅ Effective for dissipating excess heat ❌ No direct use of waste heat |
| Evaporative cooling | Water is distributed over nozzles onto filling elements (trickling elements) and releases heat into the air. | ✅ High efficiency in heat dissipation ❌ Relatively high water consumption |
| Fan support | Fans generate artificial air flow to increase heat extraction. | ✅ Increased cooling capacity ❌ Increases energy consumption |
| Water losses | Evaporation of water leads to losses that must be replenished in the cycle. | ✅ Need to replenish water ❌ Water losses due to evaporation |
| Evaporation process | Evaporation of water increases the effectiveness of the cooling tower. The steam condenses above the tower. | ✅ No steam formation in the environment, but "vapor" is produced ❌ Potentially visible steam clouds |
Cooling towers generally fall into three categories: wet cooling, dry cooling, and hybrid cooling.
Cooling Type | How It Works | Advantages | Disadvantages |
Wet Cooling | Water evaporates, transferring heat to the rising air. | ✅ High efficiency ✅ Suitable for high levels of excess energy | ❌ High water consumption ❌ Visible vapour plumes ❌ Legionella risk |
Direct Dry Cooling | Turbine steam is condensed in large air-cooled condensers. | ✅ No plume formation ✅ No risk of microbial spread | ❌ Lower efficiency ❌ High space requirements ❌ High investment costs |
Hybrid / Adiabatic cooling | Combines wet and dry cooling methods. | ✅ Low water consumption ✅ Reduced plume formation ✅ High efficiency | ❌ Higher investment costs ❌ Increased energy demand due to fans |

What Materials Are Cooling Towers Made From?
Cooling towers can be constructed from a variety of materials, depending on the type of tower and the specific requirements in terms of maintenance, efficiency, and cost. In general, a distinction is made between two main types: natural draft cooling towers and mechanically ventilated cooling towers.
- Natural draft cooling towers are typically built from reinforced concrete and wood due to their large structural size. Smaller towers of this type may also use timber or steel frameworks with sheet metal cladding.
- Mechanically ventilated cooling towers are usually made from sheet steel or glass fibre reinforced plastic (GRP). In the case of sheet steel, a further distinction is made between stainless steel and coated thin sheet metal.
Material | Advantages | Disadvantages |
Stainless Steel | ✅ Corrosion-resistant ✅ High-quality, professional appearance ✅ Hydrophobic surface properties inhibit microbial growth ✅ Fully recyclable as a single-grade material with no contamination | ❌ More expensive than other materials ❌ High unladen weight |
Coated Mild Steel | ✅ Custom colour finishes available ✅ Corrosion-resistant (provided the coating remains intact) | ❌ Coating must not be damaged ❌ High unladen weight ❌ Difficult to recycle, as the coating is classified as a contaminant (potentially hazardous waste) |
Glass-fibre Reinforced Plastic (GRP) | ✅ Lighter than steel-built cooling towers ✅ More cost-effective alternative to stainless steel | ❌ Rough interior surfaces can promote bacterial growth ❌ Difficult to dispose of, as GRP is classified as hazardous waste ❌ Material becomes brittle over time due to UV exposure |

Cooling Towers: Questions and Answers
Cooling towers are used primarily in thermal power plants to dissipate excess waste heat and create the temperature differential required for electricity generation. They play a vital role in the re-condensation of exhaust steam from turbines and are capable of cooling up to 100,000 m³ of water per hour.
Beyond power generation, cooling towers are also widely used in the chemical industry, the steel industry, and in commercial buildings such as shopping centres and sports facilities.
The price of a cooling tower depends on its cooling capacity, design type (open or closed), and the technology involved (e.g., EC fans). Additional factors such as water consumption, overall height, and optional features like sound attenuators also play a significant role. The cost for an industrial cooling tower with higher output or specialist requirements such as hybrid technology will naturally be higher than that of a standard model. If you are looking for a cooling tower for sale that balances performance with budget, our team can help identify the right configuration for your needs.
Running costs are primarily made up of energy consumption for fans and pumps, water usage, and maintenance expenditure. Hybrid cooling towers tend to have lower operating costs due to reduced water consumption, though the additional fans do result in a higher energy demand.
A cooling tower should be serviced at least once a year to maintain efficiency and prevent contamination. In cases of intensive use or specific requirements (such as Legionella prevention), more frequent maintenance is recommended.
Legionella can be effectively controlled through regular water treatment, chemical dosing, and routine maintenance of the cooling tower. A well-maintained water distribution system and carefully monitored temperature levels help keep Legionella growth to a minimum.
VDI 2047 is a German engineering guideline covering water treatment and hygiene standards for cooling towers. It establishes requirements for safe operation and the control of microorganisms within cooling water systems.
We provide a comprehensive range of cooling tower services, covering installation, maintenance, repair, and hygiene management. This includes Legionella testing and performance optimisation to ensure a long service life and maximum efficiency. If required, we can also design and build a cooling tower to your exact specifications.
A well-maintained cooling tower can last between 20 and 30 years. Its actual lifespan depends on a number of factors, including the construction type, operating conditions, and how consistently it is serviced. Consistent servicing and timely repairs extend the working life of the tower and keep it running at peak efficiency.
What sets a cooling tower apart from other cooling systems is its ability to efficiently dissipate excess heat into the environment through evaporation. Unlike air conditioning units or air coolers, which typically rely on mechanical refrigeration, a cooling tower harnesses a natural process, making it a particularly energy-efficient and environmentally friendly solution.
