Package type cooling towers are preferred in facilities with a water flow rate between 0-1200m³/hr. Since these cooling towers are produced with Fiberglass Reinforced Polyester (FRP), a material with a longer lifetime than most of its alternatives, they have low operating and maintenance costs. In fact, FRP package type cooling towers are of very high quality. Furthermore, package type cooling towers are portable since they are modular.

Site-erected cooling towers are preferred in facilities with a water flow rate over 200m³/hr. Usually, these are large plants with high water flow rate, such as, power plants, petrochemicals plants, refineries and steel mills. These cooling towers are constructed with a structure of columns and beams. Their parts are assembled on-site. In order to choose the right material for the structure of the cooling tower, its oparational lifetime, investment cost and construction period should be taken into consideration. Impregnated timber, concrete or fiberglass reinforced polyester (FRP) are commonly used material as the structure of site-erected cooling towers. Other parts which are in direct contact with water, such as, drift eliminators, spray nozzles and fill are made of PVC, PP, FRP or stainless steel to prevent corrosion. The cooling tower is placed on a cement structure at the bottom which is also used as a cold water basin.

Wet cooling tower is a heat rejection device that extracts heat from the moving water stream to the atmosphere thereby reducing the water temperature significantly. Type of heat rejection in a cooling tower is termed `evaporative` in that it allows a small portion of the water being cooled to evaporate into a moving air stream to provide significant cooling to the rest of that water stream. Think about something hot being cooled down by pouring water onto it. A wet surface cools down much faster than a dry one. Similarly, evaporative heat rejection devices, such as cooling towers are much more effective than their dry counterparts. Common applications for cooling towers are providing cooled water for air-conditioning, manufacturing and electric power generation.
