When should I rent a dry cooler instead of a cooling tower?

A dry cooler uses ambient air to remove heat from a closed-loop cooling system, while a cooling tower relies on evaporative cooling. The most suitable solution depends on factors such as required water temperatures, operating conditions, water consumption, and site-specific requirements.

Can a dry cooler be used as a temporary backup cooling solution?

Yes. Dry coolers are commonly used as temporary backup cooling solutions to maintain critical cooling-water circuits during planned shutdowns, maintenance, repairs, or unexpected equipment failures. They help minimise downtime, reduce operational risk, and keep essential processes running while permanent systems are serviced or restored.

Can multiple dry coolers be combined for additional cooling capacity?

Yes. Dry cooler rental solutions can often be scaled to meet larger cooling demands. Our experts can advise on the best configuration.

A dry cooler is typically the best option when your process can be cooled using ambient air and does not require chilled water temperatures. If the required water temperature is lower or tightly controlled, a chiller may be the better solution.

The cooling capacity you require will depend on your specific application. To size a dry cooler correctly, we typically need details such as process water flow rate, inlet and outlet temperatures, ambient conditions, fluid type, and the amount of heat that needs to be removed.

Coolworld experts will identify the right dry cooler solution for your operation.

What is a dry cooler?

A dry cooler is a heat rejection system that removes excess heat from a cooling-water circuit and transfers it to ambient air. In a cooling-water loop, a dry cooler system cools circulating water before it returns to production equipment and process systems, helping maintain safe and efficient dry cooler operation. Coolworld offers temporary dry cooler rental solutions for planned maintenance and emergency cooling needs, providing a flexible alternative to the capital investment associated with a permanent installation and the long-term dry cooler price.

Where and why is a dry cooler needed?

A dry cooler is used across manufacturing, plastics processing, chemical and petrochemical operations, food and beverage production, pharmaceutical facilities, data centres, and technical buildings.

A dry cooler system is often needed for emergency cooling following equipment failure, planned maintenance or repairs, temporary capacity increases during peak demand, seasonal temperature spikes, plant expansions, commissioning projects, and delayed delivery of permanent equipment. Dry coolers can also be integrated with associated process cooling equipment, including chillers and cold air dryers, where reliable temperature control is essential.
