A process coolant Fluid circulating system, having a heat exchanger, and wherein the heat exchanger has a plurality of tubes extending generally parallel to one another, first and second header tanks at opposite ends of the tubes, heat exchange fins mounted on the tubes transversely, an evaporation water tank located below the heat exchanger, and a pump and spray device for spraying evaporation water from the tank, a fan for forcing air through the heat exchanger so that the air evaporates at least some of the evaporation water so as to cool the air and remove heat from the process coolant fluid within the heat exchanger, a vent for venting air and vaporized water to atmosphere, and an ozone generator associated with the tank, for transferring ozone-rich gases to the tank from the ozone generator so as to reduce bacterial growth in the evaporation water in the tank.
