Product Description
drift eliminators are vital components in cooling towers and other evaporative cooling systems. They are constructed from inert polyvinyl chloride (PVC) plastic material, which effectively eliminates corrosion of these critical components. Drift eliminators are assembled in sections, facilitating easy removal for inspection and maintenance of the water distribution system. They also incorporate UV inhibitors to resist cracking and degradation due to sunlight.

4.5. Chevron Drift Eliminators
Chevron drift eliminators, also known as wave drift eliminators, have a wavy structure that forces the airflow to change direction multiple times.
Characteristics:
High Separation Efficiency: The wave-like structure increases the likelihood of droplet capture.
Moderate Airflow Resistance: Balances efficient droplet capture with maintaining reasonable airflow resistance.
Applications:
Used in various industrial cooling towers where a balance between efficiency and airflow resistance is needed.
4.6. Tri-Pass Drift Eliminators
Tri-pass drift eliminators force the airflow to change direction three times, significantly increasing droplet capture efficiency.
Characteristics:
Triple Direction Change: The three directional changes maximize droplet capture.
High Efficiency: Particularly effective in high-performance cooling tower applications.
Applications:
Ideal for high-efficiency cooling towers in industries with stringent water conservation requirements.
Conclusion
Drift eliminators are crucial in reducing water droplet emissions from cooling towers, conserving water, and minimizing environmental impact. The choice of drift eliminator type depends on specific application needs, with options ranging from cellular and blade designs to more specialized S-shape, V-shape, Chevron, and Tri-pass configurations. Each type offers distinct advantages, ensuring that there is a suitable solution for every industrial requirement. By selecting the appropriate drift eliminator, industries can achieve maximum operational safety, legal compliance, and energy savings, while also contributing to environmental sustainability.
