An evaporative cooler includes an arrangement of a combination of fluid components including flow control valves, spray bars, spray bar orifices, spray bar distribution channels, and distribution caps that produce a water application profile on the media that is adjusted to match the heat load introduced to the media by the air to be evaporatively cooled. The water evaporation rate is a direct function of this heat load profile. Applying water in this profile takes advantage of the wicking rate and flow through time constant of evaporative cooling media to effectively distribute the water through the media. This results in a once through system that allows the volume of water being applied be the lowered such that water not evaporated and exiting the media is limited and does so at very high cycles of concentration while maintaining high levels of cooling effectiveness and scale free media.
