Here’s a detailed comparison between Wooden Cooling Towers and Fiberglass (FRP) Cooling Towers to help you choose the right type for your industrial application:
1. Material & Construction
| Aspect | Wooden Cooling Tower | Fiberglass (FRP) Cooling Tower |
| Primary Material | Redwood, cedar, or treated pine | Fiberglass-reinforced plastic (FRP) |
| Corrosion Resistance | Naturally resistant to water/chemical corrosion | Highly resistant to rust, chemicals, and UV rays |
| Structural Strength | Moderate (requires sturdy framing) | Lightweight but durable |
| Weight | Heavy (needs strong foundation) | Lightweight (easier to install/relocate) |
2. Performance & Efficiency
| Aspect | Wooden Cooling Tower | Fiberglass (FRP) Cooling Tower |
| Thermal Insulation | Good (wood retains heat longer) | Poorer insulation (conducts heat slightly) |
| Cooling Efficiency | Slightly lower due to older fill designs | Higher (modern PVC fills optimize heat transfer) |
| Airflow Design | Mostly Cross flow (traditional) | Cross flow & counterflow options |
| Drift Loss | Higher (unless fitted with eliminators) | Lower (better drift eliminators) |
3. Lifespan & Durability
| Aspect | Wooden Cooling Tower | Fiberglass (FRP) Cooling Tower |
| Typical Lifespan | 20–30 years (with maintenance) | 15–25 years |
| Decay/Rot Risk | Requires regular treatment | No rot or fungal growth |
| UV Resistance | Poor (needs coatings) | Excellent (UV-stabilized resin) |
| Impact Resistance | Moderate (wood can crack) | High (flexible, crack-resistant) |
4. Maintenance & Upkeep
| Aspect | Wooden Cooling Tower | Fiberglass (FRP) Cooling Tower |
| Maintenance Needs | High (wood checks, treatments) | Low (only periodic cleaning) |
| Repair Complexity | Easy (replace individual wood slats) | Harder (requires FRP patching) |
| Chemical Treatment | Needed to prevent rot/algae | Minimal (only water treatment) |
