Cooling Tower

Cooling-water is a common utility in chemical process and energy industries. It picks up heat from various heat exchange processes. For circulating it back to the processes, it’s temperature has to be brought back to it’s original temperature. This is done by a ‘cooling-tower’. Here, the cooling-water is brought in intimate contact with ambient air.

Cooling towers are a special type of heat exchanger that allows water and air to come in contact with each other to lower the temperature of the water. During this process, small volumes of water evaporate, lowering the temperature of the water that is being circulated throughout the cooling tower.

Cooling tower nozzles are used to spray the water onto to the “fill media”, which slows the water flow down and exposes the maximum amount of water surface area possible for the best air-water contact. The air is being pulled / forced by a “cooling tower fan”.
