Drift Eliminator
A reliable component for dependable cooling-tower and condenser operation
HACST cooling-system components are selected to support efficient, serviceable operation in cooling towers and evaporative condensers. Material compatibility, operating conditions, system interfaces and maintenance access should be reviewed as part of the complete equipment design.
Specified around operating conditions and site requirements
The component specification should be considered with the equipment model, process medium, operating environment, system duty and planned maintenance routine.
- Application-led selection: the configuration begins with the actual operating duty and project objective.
- Practical integration: installation footprint, access, controls and service requirements are considered early.
- Long-term operation: material, water, airflow and maintenance considerations are reviewed for the operating environment.
Configuration and performance considerations
Overview
A drift eliminator is a critical component that prevents water droplets from escaping the cooling tower with exhaust air. It ensures water conservation, reduces chemical loss, and protects the environment.
Function in Cooling Towers
As fans drive large volumes of air through the cooling tower, small droplets can be carried upward. The drift eliminator forces the air to change direction multiple times, causing droplets to collide with surfaces and fall back into the basin.
Design & Performance
- Cellular Type: Uses honeycomb-like channels for high efficiency and compact size.
- Blade Type: Curved blades deflect air paths; suitable for large industrial towers.
High-quality drift eliminators reduce water losses to less than 0.001% of circulating flow.
Applications
Drift eliminators are used in open cooling towers, evaporative condensers, and hybrid towers to minimize visible plumes, water losses, and chemical discharge.
How to Select
- For compact factory-assembled towers → Cellular profiles are preferred.
- For large field-erected towers → Blade-type designs handle higher airflow rates.
- Material choice (PVC, PP, FRP) depends on temperature and chemical exposure.
