Pultruded Cooling Tower
A Pultruded Cooling Tower is a cooling tower whose structural framework is made from pultruded FRP (Fiberglass Reinforced Plastic) sections instead of traditional materials like wood, steel, or concrete.
Pultrusion – Quick Note
- Pultrusion = a continuous manufacturing process used to produce fiber-reinforced plastic (FRP) structural sections with high strength and corrosion resistance.
- The process pulls (not pushes) fiberglass strands through a resin bath and then through a heated die to form structural shapes (beams, channels, angles, etc.).
Key Features of Pultruded Cooling Towers
- Material Advantage
- Made from FRP structural members → highly corrosion resistant (ideal for humid, chemical, or saline environments).
- Much lighter than concrete or steel.
- UV resistant and long service life.
- Design & Construction
- Modular design → easy assembly on site.
- Strong enough to replace RCC (reinforced concrete) or timber towers in large industrial applications.
- Can be designed as induced draft counterflow or crossflow type.
- Durability
- Resistant to rust, rot, termites, and algae.
- Excellent for coastal areas, chemical plants, and places with aggressive water quality.
- Maintenance
- Lower maintenance compared to timber or metal towers.
- No periodic painting or anti-corrosion treatment needed.
Applications
- Power plants
- Petrochemical & refinery plants
- Fertilizer plants
- Coastal installations (where sea water is used)
- Chemical processing industries
