Design & Material Considerations for Drift Eliminator in Cooling tower
- Blade Geometry: The shape (chevron, wave, honeycomb) and spacing are optimized for the specific air velocity and droplet size.
- Material: Must be durable, corrosion-resistant, and fire-retardant. PVC is most common due to its excellent wetting characteristics, light weight, and cost.
- Modularity: They are typically installed in modular sections for easy maintenance and replacement.
What Happens Without Drift Eliminators (or with Failed Ones)?
- Visible plumes of mist downwind, even in dry weather.
- White salt stains on buildings, cars, and pavement near the tower.
- Dead or damaged vegetation from chemical and salt deposition.
- Rapid, uncontrolled water loss, increasing chemical and water costs.
- Potential corrosion of nearby structural steel and equipment.
