Closed Circuit Cooling Towers keep the process fluid clean and contaminant free in a closed loop. This creates 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 circuit, in which the process fluid to be cooled circulates inside the coil.

During operation, heat is transferred from the warm fluid in the coil to the spray water, and then to the atmosphere as a portion of the water evaporates.  In addition to chiller application and industrial process cooling, Closed Circuit Cooling Towers are often used in heat pump loops, where closed loop cooling is preferred.
