Crossflow is a design in which the airflow is directed perpendicular to the water flow (see diagram at left). Airflow enters one or more vertical faces of the cooling tower to meet the fill material. Water flows (perpendicular to the air) through the fill by gravity. The air continues through the fill and thus past […]

On 16 August 1916,[22] Frederik van Iterson took out the UK patent (108,863) for Improved Construction of Cooling Towers of Reinforced Concrete.[23] The patent was filed on 9 August 1917, and published on 11 April 1918. In 1918, DSM built the first hyperboloid natural-draft cooling tower at the Staatsmijn Emma, to his design. Hyperboloid (sometimes...

In a wet cooling tower (or open circuit cooling tower), the warm water can be cooled to a temperature lower than the ambient air dry-bulb temperature, if the air is relatively dry (see dew point and psychrometrics). As ambient air is drawn past a flow of water, a small portion of the water evaporates, and […]

Wet cooling towers or open-circuit Cooling Tower or evaporative cooling towers operate on the principle of evaporative cooling. The working coolant (usually water) is the evaporated fluid, and is exposed to the elements. Closed circuit cooling towers (also called fluid coolers) pass the working coolant through a large heat exchanger, usually a...

Industrial cooling towers Industrial cooling towers for a power plant Industrial cooling towers for fruit processing Industrial cooling towers can be used to remove heat from various sources such as machinery or heated process material. The primary use of large, industrial cooling towers is to remove the heat absorbed in the circulating cooling...
