Cooling Towers Guide
A reference for open and closed-circuit heat-rejection equipment used with water-cooled HVAC plants.
Where this equipment is used
Cooling towers reject heat from condenser-water or closed fluid loops serving chillers and some process or hybrid systems.
Major components and connected systems
Typical elements include basin, fill or coil, fans, motors, drives, nozzles, distribution, louvers, drift eliminators, makeup and float, strainers, heaters, pumps, treatment, controls, structure, and piping.
Common operating concerns
The same symptom can come from equipment, controls, distribution, load, utilities, or connected systems. Qualified diagnosis uses documentation and measurements.
- Scale, corrosion, fouling, leakage, vibration, drift, or poor approach
- Fan, motor, drive, fill, nozzle, basin, float, or control failure
- Water-treatment, freeze, structure, access, noise, or plume considerations
Maintenance priorities
Coordinate safe cleaning, treatment, basin and fill condition, strainers, nozzles, fans, drives, vibration, controls, winter protection, and measured performance.
Repair, retrofit, and replacement decisions
Capacity, condition, materials, treatment, structure, drift, noise, efficiency, plant downtime, access, code, and connected chiller requirements guide repair or replacement.
