Cooling tower

Cooling tower

A cooling tower is a structure used to cool the air and keep indoor environments cool and comfortable. Cooling towers are usually very tall and have a large surface area to provide maximum cooling effect. They can be either free standing or built into a building.

Most cooling towers have a compressor that uses electricity to pump the refrigerant through the system. The cooling medium circulates through the cooling tower and absorbs heat from the air passing through it. This hot air is then blown out through a fan at the top of the cooling tower.

To keep the air cool and fresh, it is important that the cooling towers are regularly cleaned and maintained. This may include replacing filters and making sure the compressor and other parts of the system are working properly.

Cooling towers are widely used in large commercial and public buildings, such as office complexes, shopping malls and airports, where they are important tools for keeping the temperature comfortable for people and other living creatures indoors.

They are also common in various types of industries, where it is important to keep products cool and store them at the right temperature. Cooling towers are also an important tool for keeping temperatures comfortable for people and other living creatures indoors.

Great need and extremely important to clean cooling towers

Cooling towers get dirty because they are exposed to airborne pollutants, such as dust, dirt, pollen and other particles. These contaminants stick to the surface of the cooling tower and can cause it to become less efficient and can even damage the system.

In addition, moisture and humidity can accumulate on the surface of the cooling tower, which can lead to mould and mildew growth. This can make the cooling tower less efficient and can also be a health risk for people who breathe in mould spores.

Legionella and cooling towers

Another major risk factor around dirty cooling towers is legionella. Legionella is present in the water distribution network and in water heaters, but can also be present and spread from humidification systems, air conditioning, cooling towers, biogas plants and scrubbers for the treatment of flue gases or process air. Legionnaires’ disease and Pontiac fever are transmitted by inhaling water aerosols containing legionella bacteria. The growth of legionella is facilitated if it grows together with other microorganisms and is therefore often found in accumulations of, for example, bacteria and algae, biofilm. It can also multiply inside amoebae and other protozoa, making the bacterium both difficult to detect and remove. The biofilm protects against both disinfectants and temporary increases in water temperature.

Cleaning the cooling tower regularly is important to prevent it from getting dirty and to make sure it works optimally. This may include removing dust and dirt from the surface, cleaning the filters and checking that all parts of the system are working properly. Keeping the cooling tower clean and well maintained can prevent it from becoming less efficient and can also reduce the risk of health problems caused by mould and other contaminants.

Why conventional methods such as pressure washing are not appropriate

It is not advisable to use high-pressure washing to clean cooling towers, as it can damage the surface of the cooling tower and make it less efficient. This is because high-pressure washing can cause cracks and microdamage to the surface of the cooling tower, especially if it is used at too high a pressure or if it is directed at angles and edge lines. This damage can reduce the efficiency of the cooling tower and can also shorten its life.

In addition, pressure washing is not always the most effective method for removing adhering contaminants, such as mould, algae and other dirt. These contaminants can be difficult to remove with a pressure washer and may require more extensive cleaning methods to remove.

Thus, care should be taken when using pressure washing to clean cooling towers, as it can damage the surface and make the cooling tower less efficient. Therefore, it is better to use other methods.

NEO method and cleaning of cooling towers

Nordic Energy Optimization uses its proprietary and innovative method, the NEO method, which is a combination of dry ice and special equipment for effective cleaning. The Neo method involves using liquid carbon dioxide ice to push dirt, contaminants and other substances off the surface of the cooling tower. This is an effective method for removing even the most stubborn contaminants, such as mould, algae and other dirt.

The NEO method also works well against legionella in cooling towers as it is an effective method to remove legionella bacteria. The method involves a temperature of minus -80 degrees Celsius, which freezes the legionella bacteria and ultimately kills them and prevents them from spreading.

Thus, the NEO method is a good method to use to control legionella in cooling towers, as it is effective, gentle and easy to use.

One of the main advantages of the NEO method is that it is a gentle method that does not damage the surface of the cooling tower. This is important because cooling towers have a very large surface area and are exposed to a lot of contamination, so using a method that does not damage the surface is important to preserve its life and efficiency.

In addition, the NEO method is a quick and easy method to use. It is also very environmentally friendly as carbon dioxide is a naturally occurring gas and does not release any harmful substances into the air.

In conclusion, the NEO method is the best method to clean cooling towers because it is effective, gentle and environmentally friendly.
