Advanced Fill Technologies
High-Efficiency/Low-Clog Film Fill
- Special surface textures
- Larger water passages
- Anti-fouling coatings
Zero Drift Fills
- Integrated drift elimination
- Reduced plume potential
Fire-Retardant Fills
- Special PVC formulations
- Required for certain locations/industries
Installation Considerations
- Module size: Typically 2′ × 4′ or 1m × 1m modules
- Support systems: Grids, beams, or cables
- Stacking pattern: Staggered for optimal flow
- Expansion/contraction: Allowance for thermal movement
Economic Impact
Fill represents 15-25% of tower cost but determines 60-80% of cooling performance
- Good fill selection: Can reduce tower size by 30-40%
- Poor maintenance: Can increase energy consumption by 15-25%
Industry Trends
- Higher surface area densities (up to 250 m²/m³)
- Sustainable materials (recyclable PVC)
- Digital monitoring for fill condition
- Anti-microbial coatings
- Modular designs for easier replacement
