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 heat exchange coil. This isolates the process fluid from the outside air, keeping it clean and free of contamination in a closed loop and creating two separate fluid circuits:

  1. An external circuit, in which spray water circulates over the coil and mixes with the outside air.
  2. An internal closed loop circuit, in which the process fluid circulates inside the coil.

Key benefits of Closed Circuit Cooling

  • Contaminant-free cooling circuit

  • Reduced system maintenance

  • Lower overall system costs due to year-round savings on maintenance, water and water treatment
