Frequently Asked Questions

What is DECSA and what does the company specialise in?

DECSA is an Italian company specialising in industrial cooling solutions, including open and closed-circuit cooling towers, evaporative condensers, and cooling solutions, and is part of the Cofinair Group.

The company is based in Voghera (Italy), in the Lombardy region of northern Italy (Province of Pavia), where its headquarters and main operations are located.

It operates on a global scale and has installed its cooling systems in over 100 countries worldwide, supplying solutions for industrial and HVAC applications across Europe and international markets.

The cooling tower works as a water-to-air heat exchanger in which the water mass is cooled by exchange with the ambient air.

In the case of cooling towers at open circuit, the direct encounter of air with process water allows a small amount of water to evaporate, and the remaining part to cool to a lower temperature, which will be recirculated in the industrial process.

In closed-circuit cooling towers, while still relying on the principle of evaporative cooling, process water remains inside a heat exchanger without coming into contact with ambient air, thus remaining free from possible contamination.

To prevent Legionella in cooling towers, it is essential to implement a regular and thorough cleaning and maintenance program. The typical conditions within these systems—such as high water temperatures and elevated humidity—can promote the growth and spread of bacteria and other potentially harmful microorganisms. Careful management significantly reduces this risk.

A key aspect is preventing water stagnation in water basins, especially during system shutdown periods. This can be achieved through targeted anti-Legionella water treatments carried out by qualified professionals. These treatments use chemicals that are safe for humans but highly effective against bacteria and microorganisms, while also helping to reduce scale and deposit formation.

In Italy, the prevention of Legionnaires’ disease is governed by specific guidelines. The main references include the “Guidelines for the prevention and control of legionellosis” issued by the Ministry of Health (2015), the “Guidelines to prevent Legionella in cooling towers” developed by ATS Brescia, and, in the Lombardy Region, the introduction of Article 60 bis through Article 36 of Regional Law 33/2019, which established a registry of evaporative cooling towers at the municipal level, strengthening monitoring and control activities.

Choosing original components in cooling towers ensures the proper operation of the equipment over time, while ensuring the thermal performance provided at the design stage. Original spare parts make it possible to:

  • Reducing downtime: Installing non-original spare parts may require the installation of additional components, thus extending the cooling tower downtime. By relying on our original spare parts, you can ensure the correct operation of your equipment and avoid sudden system downtime.
  • Maintaining predetermined performance: Installing non-original spare parts may cause premature damage to the cooling tower. Our spare parts are original and are therefore fully compatible with the equipment, ensuring that the performance specified during the design phase is maintained.
  • Reliability and safety of equipment: The use of components that do not comply with the required safety standards may increase the customer’s exposure to all kinds of risks. The quality of our products guarantees total safety and reliability for the customer, thereby minimising potential risks.
  • Improved performance: Non-genuine spare parts can lead to a decline in the cooling tower’s performance and production efficiency, particularly during periods of peak usage, thereby incurring additional costs and, in the worst-case scenario, causing damage to the machine. Ensure optimum performance with our spare parts.

A word from Decsa’s
Managing Director

Nicola left a deep mark at the company; he was and still is part of it. Under his leadership, the company has undoubtedly embarked on a path that has meant, above all, caring for the environment and people, because, after all, the company is made up of people and foresight.

Joining the company as my first job was a bit like leaving the family that sent me to school and entering another family. If you find a family like I did, everything becomes a little easier.
