The main function of the cooling tower drift eliminator (also known as a water remover or water stopper) is to reduce water droplets drifting out of the tower with the airflow (water loss), while ensuring ventilation efficiency. Its typical characteristics can be seen from three aspects: performance, structure, and materials:
Functional Features
1.Efficient water collection (good defogging performance)
It can effectively capture water droplets carried away by the airflow, reducing the float rate to ≤ 0.001% to 0.01%, significantly saving water replenishment.
2.Reduce water consumption and operating costs
Reduce cooling water loss, lower water replenishment, chemical consumption, and sewage discharge costs.
3.Improving Environmental Impact
To prevent the occurrence of "white mist" and "water mist dispersion" outside the tower, and to avoid corrosion of surrounding equipment, slippery ground, or impact on surrounding buildings.
Structural characteristics
1.Multi fold or waveform channel design
By changing the direction of the airflow, water droplets are caused to collide with the surface of the blades due to inertia and fall back into the tower.
2.Low resistance and smooth ventilation
While ensuring water collection efficiency, minimize the impact on wind resistance and avoid significantly increasing fan energy consumption.
3.Modular combination installation
Usually in the form of sheet or block structures, it is easy to install, disassemble, and maintain.
Material characteristics
1.Strong corrosion resistance
Common materials: PVC, PP, fiberglass reinforced plastic (FRP), etc., suitable for humid, high temperature, and chemical water environments.
2.Lightweight and high strength
Not easily deformed and has a long service life.
3.Aging resistance and flame retardancy are optional
Flame retardant or UV resistant materials can be selected according to the needs.
Why are cooling tower drfit eliminators so popular in the Japanese market
Cooling tower drift eliminators are particularly popular in the Japanese market, mainly because Japan has extremely high requirements for water conservation, environmental protection, and refined management of equipment operation. At the same time, urban buildings are dense and the site is small. If cooling towers produce floating water, it can easily affect the surrounding environment and public health. Efficient drift eliminators can significantly reduce the floating rate, minimize water resource waste, and reduce the risk of bacteria (such as Legionella) spreading with water mist, in compliance with Japan's strict environmental regulations and safety standards; In addition, it has low noise, easy maintenance, and stable operation, which is very suitable for the Japanese market's demand for high-quality, low failure rate, and long-term reliable equipment. Therefore, it is widely used and has formed a mature market.
