Components & Features of Induced Draft Cross Flow Cooling Tower

1. Top-Mounted Fan (Induced Draft):
   1. Positioned at the air discharge point
   1. Creates negative pressure throughout the tower
   1. Handles saturated air (requires corrosion-resistant materials like fiberglass or alloys)
2. Open Gravity Distribution System:
   1. No pressure nozzles (minimal clogging)
   1. Basins have metering orifices or weirs
   1. Easy visual inspection and cleaning

1. Vertical Fill Arrangement:
   1. Typically splash-type fills (bars, grids)
   1. Arranged in vertical banks
   1. Creates multiple water breakup points
2. Peripheral Air Inlet Louvers:
   1. Large openings on tower sides
   1. Often angled to prevent water splash-out
   1. Provide uniform air distribution
3. Drift Eliminators Above Fill:
   1. Capture water droplets before air exits
   1. Reduce water loss to 0.001-0.005% of circulation
