A pultruded cooling tower is made from fiber-reinforced polymer (FRP) components manufactured using the pultrusion process, offering high strength, corrosion resistance, and lightweight properties. Below is a detailed list of parts used in a pultruded cooling tower:
1. Structural Components
- Pultruded FRP Columns – Vertical load-bearing members.
- Pultruded Beams & Braces – Provide structural support and rigidity.
- FRP Grids/Platforms – Walkways and maintenance platforms.
- Base Frame/Support Structure – Typically FRP or galvanized steel for stability.
2. Heat Transfer Components
- FRP Fill Media (Film or Splash Type) – Increases water-air contact for efficient cooling.
- Drift Eliminators – Reduces water droplet carryover (drift loss).
- Water Distribution System
- FRP Nozzles – Spray water evenly over fill media.
- PVC/FRP Distribution Pipes – Carry water to nozzles.
3. Fan & Drive Assembly
- FRP Fan Cylinder (Fan Stack) – Houses the fan and directs airflow.
- FRP Fan Blades – Lightweight, corrosion-resistant.
- Motor & Gearbox (if applicable) – Mounted on FRP supports.
4. Water Containment System
- FRP Cold Water Basin – Collects cooled water (often integrated into the structure).
- FRP Louvers – Controls airflow and prevents sunlight/algae growth.
5. Miscellaneous Components
- FRP Casing/Panels – Encloses the cooling tower.
- FRP Access Doors – For inspection and maintenance.
- FRP Fasteners & Connectors – Corrosion-resistant bolts, nuts, and clips.
- FRP Mist Eliminators – Further reduces water loss.
Advantages of Pultruded FRP in Cooling Towers:
◉ Corrosion-resistant (ideal for harsh environments).
◉ Lightweight (easier installation & reduced structural load).
◉ High strength-to-weight ratio (durable with minimal maintenance).
◉ Long lifespan compared to wood or metal.
