A multi-stage distribution and return control system for use in an evaporative cooling system including a drip conductor, a plurality of cooling cells along which water from the drip conductor passes and a gutter therebelow, including a tank, a conduit for conveying fresh water to the tank and a valve for regulating flow therethrough, a pump within the tank, a conduit for conveying water from the pump to the drip conductor, a conduit for conveying water from the gutter to the tank; high, mid and low-level switches and a float for movement between the switches, and a control system which when cooling is desired opens the valve for conveying fresh water to the tank until the float engages the mid-level switch and for starting the pump until the float engages the low-level switch, stopping the pump until water fills the tank again to the level defined by the mid-level switch and, moreover, when enough water is evaporated from the cooling cells, and the water level falls below the mid-level switch opening the valve again filling the tank to the level of the mid-level switch and, moreover, turning off the pump and valve when the temperature reaches the predetermined, desirable low level and, moreover, when water returning from the cooling cells is of sufficient volume to activate the high-level switch starting the pump until the float deactivates the low-level switch at which time the pump is turned off.

[ What is claimed is:] [1.] In an evaporative cooling system including a drip conductor, a plurality of cooling cells along which water from the drip conductor passes and a gutter therebelow, the improvement comprising:a tank,a conduit for conveying fresh water to the tank and a valve for regulating flow therethrough,a pump within the tank,a conduit for conveying water from the pump to the drip conductor,a conduit for conveying water from the gutter to the tank,high, mid and low-level switches associated with the tank and a float for movement between the switches; andmeans, when cooling is desired, for opening the valve for conveying fresh water to the tank and for operating the pump conveying water to the drip conductor until the float engages the low-level switch, stopping the pump until water fills the tank again to the level defined by the mid-level switch and, moreover, when enough water is evaporated from the cooling cells and the water level falls below the mid-level switch at which time the float engages the mid-level switch opening the valve again filling the tank to the level of the mid-level switch and, moreover, turning off the pump and valve when the temperature reaches the predetermined desirable low level and, moreover, when water returning from the cooling cells is of sufficient volume to activate the high-level switch starting the pump until the float deactivates the low-level switch at which time the pump is turned off.
