Water Distribution System in Cooling Tower Process

Distribution of water within the circuit of cooling tower is responsibility of tower manufacturer. The

magnitude and routing of the circulating water lines between the heat source and the tower location are usually dictated by the type of tower, typography and site layout.

Crossflow tower configuration permits the use of a gravity-flow distribution system wherein the supply of water is elevated to hot water distribution basins above the fill, from which it flows over the fill through metering orifices located in the distribution basin floor.

Gravity systems are readily inspected, cleaned and maintained and easily balanced but contribute negligibly to overall heat transfer, tend to require a higher pump head in larger towers and may promote the formation of algae unless the open basins are covered.
