Abstract

An evaporative fluid cooling apparatus includes a cooling housing, at least two fluid coils, an air movement apparatus, and one or more spray apparatuses. The cooling housing defines a cooling chamber with an air housing input and an air housing output. The fluid coils are positioned in and extend across at least a portion of the cooling chamber in a spaced apart stacked arrangement. One of the fluid coils is positioned closer to the air housing output and has a first fluid input configured to be coupled to a fluid return from one or more air handler devices and a first fluid output coupled to a second fluid input to the other fluid coil. The other fluid coil is positioned closer to the air housing input and has a second fluid output configured to be coupled to a fluid supply to the air handler devices.
