Film Packing (Film Fill) in Cooling TowersFilm packing (or film fill) is a high-efficiency cooling tower fill media designed to maximize heat transfer by spreading hot water into a thin film over a large surface area

enhancing evaporation and cooling. It is the most common and thermally efficient fill type used in modern cooling towers.

How Film Packing Works

1. Water Distribution: Hot water is evenly sprayed over the top of the film fill.
2. Film Formation: Water flows down corrugated PVC or PP sheets, forming a thin, turbulent film.
3. Air Contact: Cooling air passes vertically (counterflow) or horizontally (crossflow), absorbing heat from the water film.
4. Cooled Water Collection: The chilled water collects in the basin for recirculation.

Key Features of Film Fill

 Material: Made of PVC, polypropylene (PP), or advanced plastics (corrosion-resistant).
 Design:

• Corrugated sheets with small, engineered channels.
• Vertical (counterflow towers) or horizontal (crossflow towers) orientation.
   Surface Area: Provides 3–10× more contact area than splash fill.

Advantages of Film Fill  Highest Thermal Efficiency: Ideal for precision cooling (e.g., HVAC, data centers).
 Compact Design: Requires less space than splash fill for the same cooling capacity.
 Energy Savings: Reduces fan and pump power due to optimized airflow.

 Low Water Consumption: Enhances evaporation rates, saving makeup water.

Disadvantages of Film Fill

 Clogging Risk: Susceptible to fouling from debris, algae, or scale (needs clean water).
 Higher Maintenance: Requires regular cleaning and water treatment.
 Fragility: Thin sheets can degrade under UV exposure or harsh chemicals.

Where is Film Fill Used?

• HVAC systems (office buildings, hospitals).
• Power plants (closed-loop cooling).
• Food & beverage industry (clean water applications).
• Petrochemical plants (with proper water treatment).
