Typical Applications of Field-Erected Cooling Towers

  • Electric Power Generation (Nuclear, Fossil, Geothermal)
  • Heavy Industrial & Chemical Processing Plants
  • Hydrocarbon/Petrochemical Refineries
  • Large HVAC Systems for District Cooling, Campuses, or Major Data Centers
  • Steel Mills & Manufacturing Facilities

Advantages vs. Factory-Assembled Towers

Advantages of FEPDisadvantages of FEP
Customization: Tailored to exact site/process needs.Longer Installation Time: Significant on-site labor and construction schedule.
High Capacity & Scalability: Virtually no upper size limit.Higher Initial Cost: More engineering and field labor required.
Superior Durability & Longevity: Industrial-grade materials.Site Dependency: Weather and site logistics can impact cost/schedule.
Maintainability: Designed for component-by-component access and repair.Complex Logistics: Coordinating delivery and storage of many components.
Long-Term Efficiency: Often achieves closer approach temperatures.Requires Heavy Equipment: Cranes, lifts, etc., needed for assembly.

Key Selection & Specification Considerations

  1. Heat Load & Approach Temperature: The core thermal performance requirements.
  2. Site Space & Layout: Footprint and height restrictions, proximity to other structures.
  3. Water Quality: Determines fill type (e.g., film fill may foul with poor water treatment).
  4. Environmental Factors: Wind, seismic zone, ambient wet-bulb temperature, plume visibility, and sound level limits.
  5. Life-Cycle Costing: Evaluating initial capital cost versus long-term operational efficiency and maintenance costs.

In summary, Field-Erected Cooling Towers are the industrial workhorses of heat rejection. They represent a major capital investment but are chosen when reliability, customization, massive capacity, and decades of service are required for critical industrial processes.
