Film Fill vs Corrugated Fill
Film Fill vs Corrugated Fill
Film Fill and Corrugated Fill are both widely used in cooling towers to increase the contact area between water and air. However, they are not exactly the same. The main difference is the structure of the fill and the way it distributes water and air through the cooling tower.
1. What Is Film Fill?
Film Fill uses thin plastic sheets to spread water into a thin film. The large wetted surface area increases contact between water and air, helping improve heat transfer efficiency.
Film Fill is commonly used in HVAC and industrial cooling towers where high cooling efficiency is required.
For more information, see our Film Cooling Tower Fill.
2. What Is Corrugated Fill?
Corrugated Fill uses plastic sheets with a corrugated or wave-shaped structure. The corrugated surface helps distribute water across the fill and creates flow channels for air and water.
Depending on the fill design, corrugated structures can also provide a large contact area while maintaining effective airflow.
For different corrugated fill designs, see our Corrugated Tower Fill.
3. Film Fill vs Corrugated Fill
| Feature | Film Fill | Corrugated Fill |
|---|---|---|
| Structure | Thin plastic sheets designed to form a water film | Corrugated or wave-shaped plastic sheets |
| Water Distribution | Forms a thin water film across the sheet surface | Corrugated channels help distribute water |
| Heat Transfer | High efficiency with a large wetted surface area | Efficient water-air contact depending on the corrugated design |
| Airflow | Depends on flute design and spacing | Depends on corrugation structure and channel design |
| Typical Applications | HVAC and industrial cooling towers | Industrial and cooling tower replacement applications |
4. How to Choose the Right Fill?
The right choice depends on the cooling tower design, water quality, operating temperature and cooling requirements. In many cases, the terms Film Fill and Corrugated Fill may also overlap because some film fills use corrugated sheet structures.
If you are replacing existing fill, check the existing fill structure and dimensions carefully. Providing photos, drawings or samples can help identify a suitable replacement.
For customized replacement projects, our Corrugated Film Fill can be manufactured according to your existing cooling tower fill specifications.
