What Exactly Is a Cooling Tower?

Water cooling towers

A cooling tower is a heat rejection device, which extracts waste heat to the atmosphere though the cooling of a water stream to a lower temperature. Evaporative heat rejection devices such as evaporative cooling towers, water cooling towers and aeration tower systems are commonly used to provide significantly lower water temperatures than achievable with “air cooled” or “dry” heat rejection devices, like the radiator in a car, thereby achieving more cost effective and energy efficient operation of systems in need of cooling.

There are two main configurations of factory assembled cooling towers: crossflow and counterflow. In crossflow cooling towers, the water flows vertically down the fill as air flows horizontally across. In counterflow cooling towers, the water flows vertically down the fill as air flows vertically up.

If you are looking to purchase entire towers or need cooling tower replacements, you have access to dozens of reputable suppliers and manufacturers at your finger tips. When evaluating the cost of a cooling tower, analyze the cost of energy to power the fans, water lost to evaporation, chemicals, maintenance and repairs. Do not be afraid to shop around with several manufacturers. You will find one that offers the best towers for your needs and budget. Helpful links.
