How do Cooling Towers work?
Cooling towers are effectively an organic heat exchanger. Warm or hot water from a process is cooled by passing it through the tower and back out again into the process.
A cooling tower enables the water to meet the air so that some of the water evaporates, lowering the overall water temperature.
Water is pumped – usually from either the basin of the tower or a sump tank below the cooling tower – through pipework to the process. This then returns to the cooling tower. The water is either sprayed by nozzles onto the fill media (counterflow) or returns to a top tank to gravity drain onto the fill media. This part of the process maximises air to water contact. The water flows over the fill media – or packing – meeting the air which is pulled (induced draft) or pushed through (forced draft) by a fan. This is referred to as evaporative cooling.

Cooling Tower Design Options
Aqua can supply cooling towers in a variety of materials, the most common being galvanised, stainless steel (304 or 316) and glass-reinforced plastic (GRP).
Galvanised stainless steel is the most popular option as it is the most cost-effective. Yet in environments that might be corrosive, we’d recommend stainless steel and glass-reinforced plastic cooling towers as a better option.
Aqua Cooling can also create low-profile cooling towers, which are best suited for city centres and rooftop applications. We can add centrifugal fans and silencers to reduce noise pollution wherever needed, because we don’t just sell cooling towers. Our expert team have the knowledge and skill to customise and build a cooling tower for any business in the UK.
Regular Maintenance Options
Water treatment & regular maintenance are key to keeping a cooling tower operating safely and efficiently. The correct treatment plan will protect against scale build up, corrosion, fouling and microbiological contamination, including Legionella. Please note, good care of a cooling tower is a legislative requirement. Our Service team can give you full support here – call 0333 004 4433 for free, no-obligation advice.

Closed Circuit
A closed-circuit cooling tower includes a heat exchanger. The process water is separated from the ambient air so quality, and cleanliness is maintained. However, the heat exchanger adds to the size of the tower and can impact on cost.
Open Circuit
With open circuit, process water comes directly into contact with the external air stream. Disadvantages with the open design is that any contaminate within the air is passed into the water. Over time, because the water is treated and softened, these substances can build up within the system.
Crossflow
The air and water flow effectively cross each other, the air flows horizontally and the water drops vertically through the fill media. This enables variable flow in addition to lower water noise, when compared to a counterflow tower.
Counterflow
Air is pushed up vertically, counter to the water which is flowing downwards under gravity. Because it’s not possible to take advantage of the gravity flow, pressurised spray systems are used to spray the water onto the fill media. The spray system maximises heat transfer and this design is less likely to freeze in low ambient conditions. Counterflow towers tend to be more efficient and have smaller footprints, so better suited if space is restricted. This style of cooling tower often uses a more powerful fan, so sound attenuation packages can be added if the location is noise sensitive.

Frequently
asked questions
Cooling towers are used to reject heat from processes, HVAC systems, refrigeration plant and power generation. They work by evaporating a small portion of the circulating water into a moving air stream to cool the remainder. They are common in large manufacturing, chemical, pharmaceutical and data centre applications.
Cooling towers do present a legionella risk because they use warm water in contact with air which are conditions that can support bacterial growth. Managing this risk through a water treatment and inspection programme as required by ACOP L8 legislation is essential. Aqua can support you with a full water treatment and compliance service.
Cooling towers lose water through evaporation, drift, and blowdown. The exact usage depends on the size of the system and the heat load. Aqua can estimate water consumption for a proposed system and also advise on water saving measures such as drift eliminators and chemical programme optimisation.
The main alternatives are adiabatic coolers and dry air coolers. Both avoid the legionella management requirements of a cooling tower and use less water. However cooling towers can achieve lower fluid temperatures in high ambient conditions. Aqua will help you compare the options for your application.
Yes. Aqua’s Sales and Installation teams can design, supply, and install a new cooling tower as part of a complete temperature control system. We also offer ongoing service, water treatment, and maintenance support once your tower is operational.

Keeping the World’s Data Cool
4D Data Centres is a UK-based colocation provider offering ultra-fast connectivity, cloud, and cyber solutions worldwide. Data centres power nearly all online technologies but require significant energy for both operation and cooling. When 4D acquired a Gatwick facility, Aqua upgraded its live chiller-based system with an intelligent, energy-efficient cooling solution—significantly reducing mechanical cooling needs and introducing fresh air free cooling.
