Key Decision for Selection of Closed-circuit cooling tower
- Fluid Cleanliness is Critical: If scaling or contamination would damage sensitive equipment or halt production.
- Process Fluid is Expensive or Treated: If the loop contains high-cost corrosion inhibitors or specialized fluids.
- Freeze Protection is Needed: In environments with sub-zero temperatures.
- Installation Location is Constrained: When the tower must be placed indoors, on a rooftop with weight limits, or in a dirty environment.
- Life-Cycle Cost Focus: Higher initial cost is justified by lower water treatment expenses, reduced maintenance on process equipment, and higher system reliability over 15-20 years.
In summary, Closed Circuit Cooling Towers are applied wherever the reliability, purity, and precise control of the cooling fluid are as important as the cooling capacity itself. They are the engineering
solution for marrying the high efficiency of evaporative cooling with the protection of a closed hydraulic system
