Wooden Cooling Tower Manufacturer inOman

In wooden cooling towers, splash bars are typically made from naturally durable, rot-resistant wood or (in modern retrofits) alternative materials. Here’s a detailed breakdown of the types used:

1. Traditional Wooden Splash Bars

(Most Common in Legacy Towers)

Materials:

• Redwood (Sequoia sempervirens)
  • Why? Naturally resistant to decay, insects, and water absorption.
  • Lifespan: 20–30 years with maintenance.
• Western Red Cedar (Thuja plicata)
  • Why? Lightweight and contains natural oils that repel moisture.
  • Lifespan: 15–25 years.
• Cypress (Cupressus spp.)
  • Why? Performs well in humid climates.
  • Lifespan: 15–20 years.
• Treated Southern Yellow Pine (Pressure-treated with ACQ/CCA)
  • Why? Low-cost alternative but requires chemical preservatives.
  • Lifespan: 10–15 years (shorter than redwood/cedar).

Design:

• Shape: Flat or slightly curved slats (1″–2″ thick, 3″–6″ wide).
• Arrangement: Stacked in grids or lattice patterns to maximize water breakup.

Pros:
Naturally corrosion-resistant (no rust).
Biodegradable and sustainable.

Cons:
Requires regular maintenance (fungicide/algae control).
Prone to scaling/mineral buildup over time.

. Modern Retrofit Splash Bars

(Used to Replace Worn-Out Wooden Bars)

Materials:

• PVC (Polyvinyl Chloride)
  • Why? Immune to rot, lightweight, and low-maintenance.
  • Lifespan: 15–20 years.
• PP (Polypropylene)
  • Why? Chemical-resistant for harsh water conditions.
  • Lifespan: 20+ years.
• Stainless Steel (Rare)
  • Why? Used in extreme chemical environments.
  • Lifespan: 25+ years.

Design:

• Shape: Molded plastic grids or corrugated sheets.
• Advantage: Higher thermal efficiency than wood.

Pros:
Zero maintenance (no rot/scaling).
Improved cooling efficiency.

Cons:
Higher upfront cost.
Not biodegradable.

3. Hybrid Splash Bars

• Wood + Plastic Composites:
  • Example: Wood core with PVC coating.
  • Balances natural durability with modern efficiency.

Comparison: Wood vs. Modern Splash Bars

Feature	Wooden Splash Bars	PVC/PP Splash Bars
Material	Redwood, cedar, treated pine	Plastic (PVC/PP)
Lifespan	15–30 years (with upkeep)	15–25 years (maintenance-free)
Efficiency	Moderate (droplet-based)	High (film-enhanced)
Maintenance	High (wood rot, algae)	Low (just cleaning)
Cost	Lower upfront	Higher initial cost
Eco-Friendliness	Biodegradable	Plastic waste

Key Takeaways

1. Traditional wooden towers use redwood or cedar splash bars for natural durability.
2. Modern upgrades often replace wood with PVC/PP bars for better efficiency and less maintenance.

Treated pine is a budget option but has a shorter lifespan
