Factory Assembled Cooling Towers (FAP), also called Package Cooling Towers, are completely manufactured, assembled, and tested at the factory before being shipped as one or several modular units to the installation site.
What Defines an FAP Cooling Tower?
Complete Factory Assembly: All components (structure, fill, fans, basins) are assembled at the factory.
Modular Shipping: Transported as whole units or in large sections (e.g., single-cell or multi-cell modules).
Limited Field Work: Requires only connection to piping, electrical, and placement on a foundation.
Standardized Design: Built to standard capacities and configurations (though some customization is possible).
Common Construction & Materials
Component
Typical Material
Casing/Structure
Galvanized steel, stainless steel, fiberglass (FRP), or thermoplastic (PVC)
Fill Media
PVC (film or splash type), sometimes polypropylene
Cold Water Basin
Molded plastic (HDPE), stainless steel, or coated steel
Fans
Axial (FRP or aluminum), centrifugal for smaller units
Drift Eliminators
PVC cellular-style blades
Distribution System
PVC piping with ABS nozzles (Counter Flow ) or gravity basins (Cross Flow)
Standard Configurations
1. By Airflow & Design
Induced Draft, Cross Flow: Most common commercial type.
Induced Draft, Counter Flow : More compact, higher efficiency.
Forced Draft: Less common, used for specific applications.
