Closed Circuit Cooling Towers use a clean, closed loop, in a highly efficient evaporative heat transfer process.

Closed Circuit Coolers

Principle Operation

Closed circuit cooling towers operate in a manner similar to open cooling towers, except that the heat load to be rejected is transfered from the process fluid (the fluid being cooled) to the ambient air through a heat exchange coil. The coil serves to isolate the process fluid from the outside air, keeping it clean and contaminate free in a closed loop. This creates two separate fluid circuits:

  1.  an external circuit in which a small amount of spray water circulates over the coil and mixes with the outside air.
  2. an internal circuit in which the process fluid circulates inside the coil.

During operation, heat is transferred from the internal circuit, through the coil to the spray water, and then to the atmosphere as a portion of the water evaporates.

RCF Series

Counterflow Closed Circuit Cooler

RCF Closed Circuit Cooling Towers deliver fully rated thermal performance over a wide range of flow and temperature requirements. The RCF shares the superior and unrivaled features found in the popular PCT range of cooling towers. The Pultruded Composite structure employs the same patented bonded panel to post connection adding rigidity to the structure resulting in superior strength far exceeding that acheived in conventional bolt jointed FRP panels.
