How can water use be reduced in evaporative and adiabatic cooling systems?

Modern evaporative coolers use automatic blowdown systems controlled by conductivity sensors, partial recovery of discharge water, and optimized make-up strategies. Adiabatic systems, on the other hand—with the proper use of sensors and PLC-based parameter settings—use water only during periods of maximum thermal load, reducing overall consumption compared to traditional cooling towers (though with some loss of efficiency). The adoption of recovery circuits also allows part of the water to be reused in any cooling system that relies on this resource.

Configuration software used by some cooling-technology manufacturers selects systems based on water availability and cost in the installation area. The goal is to balance cost, cooling efficiency, and sustainability.
