Cooling towers

Torraval Cooling cooling towers are efficient and reliable equipment for cooling all types of industrial or air conditioning processes. With more than 60 years of experience as manufacturers of cooling towers tailored to the needs of each client and adapted to the most demanding conditions, at Torraval we design open and closed towers, induced and forced draught, factory-assembled or on-site and for all types of flow rates.

At Torraval we have the right tower for each cooling process. We also offer a wide range of after-sales services for the maintenance of cooling equipment and any other equipment on the market: spare parts, technical inspections, revamping and retrofitting.


Open circuit cooling towers, also known as evaporative cooling towers, the hot water to be cooled is pumped to the top of the tower, where it is distributed over the fill. Air is driven upward through the fill by fans, which causes some of the water to evaporate rapidly. The cooled water is collected at the bottom of the tower and recirculated in the process.

In closed cooling towers, also known as dry coolers, instead of the filler for temperature transfer, we will find a coil. The fluid to be cooled flows inside the coil of the tower, while, on the outside, water is sprayed over the coil to cool it, the evaporation of the water cools the remaining fluid without losing it, resulting in lower water consumption and lower maintenance costs. The installation of closed-loop towers is widely used in power plants, refineries, chemical and food industries.

Cooling towers are installations that use the principle of water evaporation.

This process involves the evaporation of a small portion of the water volume. By changing state to steam, this evaporation extracts energy from the non-evaporated water flow, thus providing an efficient cooling solution for various industrial processes and air-conditioning systems.

In modern cooling towers, the heat exchange between water and air is optimized by efficient components. To understand this process, it is crucial to understand two concepts: sensible heat and latent heat. Sensible heat refers to the energy required to change the temperature of a physical element, while latent heat involves the change of state of a substance due to the absorption or release of heat.

For a cooling tower to operate effectively, it must provide ample surface area contact between water and air. This is achieved by a specially designed fill to maximize heat exchange. This surface area must be selected according to the quality of the water to be cooled, the possible liquids in suspension, its efficiency and the ease of subsequent maintenance.

There are several types of cooling towers that can be classified and grouped according to different characteristics.


In evaporative cooling towers, part of the fluid evaporates when it comes into contact with the air, thus cooling the rest of the fluid. This evaporation process is essential for its operation.

In non-evaporative cooling towers, the evaporation process does not occur for cooling. A different mechanism is used.

Water and air contact:

In open circuit towers the water is in direct contact with the air, allowing heat to dissipate. The contact surface between water and air is crucial to the cooling capacity of the tower.

In closed circuit towers the water and air have no direct contact. A coil in the center of the tower allows the water to circulate, while the air, from the outside, steals heat by wetting the tubes, thus cooling the fluid.

Air draft:

Natural draft cooling towers are large structures where air moves by density difference, without the need for additional energy. They are safe and efficient for large water flows, but their size and cost can be limiting.

In the case of mechanical draft cooling towers, they use fans to drive air through the fill.

Induced draft towers have fans at the top that draw air, while forced draft towers have fans at the bottom that push air upward.

In addition to these towers, there are other cooling solutions, such as adiabatic systems or hybrid towers, which offer alternatives for various industrial applications and sectors.

Main structure: provides containment and support for the cooling tower.

Fill or heat exchange pack: present in open circuit towers, this component facilitates heat exchange between water and air.

Axial or centrifugal fan: the only mechanical device in motion, this fan drives the evaporation of the water necessary for the cooling process.

Water distribution system: usually consisting of a series of pipes and nozzles, this system ensures uniform water distribution throughout the tower.

Droplet separator: located just upstream of the fan, its function is to retain water droplets that would otherwise be carried away by the airflow from the fan.

The nature of the water to be cooled significantly affects both the choice of construction materials to be used and the most suitable type of filler. In the presence of particularly aggressive or acidic water, stainless materials or fiberglass, intrinsically insensitive to most chemical agents, should be preferred.

Cooling towers need a regular maintenance program and, in case of problems, additional attention. Although their construction is simple, keeping them in optimal condition involves following some essential guidelines to ensure safety and efficiency and maximizing their service life:

Periodic inspections: inspect the tower for damage or wear.

Cleaning: cleaning the tower regularly is important to remove dust, dirt and algae.

Water treatment: the water should be treated to prevent scaling and corrosion. It is crucial to control and condition the water to prevent physical and chemical deterioration. A clean and well-treated cooling tower ensures maximum performance with minimum consumption of electricity and evaporated water.

Preventive maintenance: perform regular preventive maintenance to identify, prevent and solve potential problems.

Cooling towers find a wide range of applications, mainly in the industrial field, but they can also be used in civil applications, such as public or commercial buildings.

In the industrial sector, both open-circuit and closed-circuit cooling towers are used. These towers are used in evaporation systems for a variety of applications, including:

Industrial refrigeration: widely used in various industries, such as food and beverage, to optimize efficiency and resources (water and energy) in food production and storage lines.

Commercial refrigeration: present in commercial establishments and supermarkets to maintain proper temperature conditions.

HVAC (Heating, Ventilation and Air Conditioning): integrated in air conditioning systems for commercial and industrial buildings.

Industrial processes: essential in a variety of industrial processes requiring temperature control, such as in oil and gas plants, as well as in the tire, paper and biomass industries. This last area represents one of the most important applications for cooling towers.

Efficiency: cooling towers are an efficient way to cool water and other liquids.

Ecology: these types of solutions do not use chemical refrigerants, which makes them more environmentally friendly than other cooling systems.
