Principle of operation  Closed-Circuit cooling towers or fluid coolers operate just like the open type, but dissipate the process fluid heat load into the ambient air via a closed-circuit heat exchanger. This isolates the process fluid from the outside air, keeping it clean and free of contamination in a closed loop and creating 2 separate...
