Introduction

Selecting the correct material for cooling tower fill is essential for long‑term durability and stable cooling tower performance.

Common Cooling Tower Fill Materials

PVC Cooling Tower Fill

PVC is widely used because of its corrosion resistance, lightweight structure, and cost efficiency.

PP Cooling Tower Fill

PP fill media offers higher heat resistance, making it suitable for systems with elevated water temperatures.

Wood Cooling Tower Fill

Older cooling towers sometimes used wooden splash bars. While durable, they require more maintenance and are less common today.

Material Comparison

• PVC – cost effective
• PP – high temperature resistance
• Wood – traditional but less efficient

Conclusion

Material selection should be based on operating conditions, water chemistry, and system design.
