Closed-loop cooling and dry coolers
Closed-loop cooling circulates the same water or water-glycol mix through a sealed system instead of evaporating it, so ongoing water consumption is low. A dry cooler is the outdoor heat exchanger that rejects that heat to ambient air with fans, without evaporation. The tradeoff is higher fan or chiller energy on hot days, so climate, power availability and water scarcity drive the choice.
