Cross Flow Cooling Tower

In crossflow cooling towers, the water flows freely into the distribution basin (hot water basin) located in the upper part of the tower. At the bottom of the distribution basin are holes wherein nozzles are installed that distribute the water onto the fill located beneath them. The water flows onto the fill and is cooled by the surrounding air, which is forced by the fan into the tower itself. The air, as aforementioned, flows horizontally, perpendicular to the cooled water. The fill type, its depth, and its height determine the degree to which the water is cooled.

The fan in the crossflow tower can be of forced type (located on the side of the tower) or induced type (located atop the tower). The tower can operate with a single distribution basin, called a single-side tower; or two distribution basins with an inducing fan between them, called a dual-side tower.
