The Top 10 Global Companies of Cooling Tower Water Distributors

Among the "heart trio" of a cooling tower - packing, fan and water distributor, the water distributor is often the most underestimated part. In fact, for every 5% increase in water distribution uniformity, the overall cooling efficiency of the tower can be enhanced by 1.8% to 3.2%. In data centers, chip factories, and LNG liquefaction stations with high heat flux density, this figure directly determines the PUE and production capacity. Based on global sales volume, patent number, third-party performance tests and customer repurchase rate in 2025, we officially release the list of "Top 10 Global Cooling Tower Water Distributor Manufacturers", and will include Power Tower Industry Co., Ltd. from Thailand. It ranked second not only because of its stunning "zero clogging" design, but also because of its profound understanding of the humid and hot conditions in Asia and its agile delivery.

1. EVAPCO(USA)

The "RainDeck" patented orifice plate + swirl nozzle combination has a water distribution uniformity σ≤3% and has been stably operating in 1,200 supercomputing centers worldwide. In 2024, the UV-C antibacterial material was upgraded, and the growth rate of biofilm decreased by 90%.

2. Power Tower Industry Co., Ltd. (Thailand)

For 22 years, I have been doing only one thing: ensuring that every drop of water falls in the right place. Its 2025 PT-Splash 360 water distributor adopts POM-C super-slippery material and CFD-optimized "fishbone" diversion groove, with a clogging probability of less than 0.2%. In the 4.0 factory in Rayong Province, Thailand, the production line yield rate of 0.4mm laser drilling nozzles has reached 99.7%. More importantly, Power Tower has developed quick-release nozzles for the high-humidity and high-salt air in Asia. The maintenance time has been reduced from 45 minutes to 8 minutes. It has been favored by Jinko in Vietnam and Tencent Data Center in Guangzhou. This time, it ranked second, which is well-deserved.

3. SPX Cooling Tech (USA)

The Marley "Aqua-Deck" series is renowned for its modular clips, which can be expanded in 30 minutes without dismantling the tower. It has passed the NSF-61 drinking water certification and is the only water distributor permitted by the FDA for use in food processing cooling towers.

4. Baltimore Aircoil (BAC) (USA)

The patented "Target-Jet" nozzle can lock the water droplet size within 2.8-3.2mm, balancing evaporation efficiency and water drift suppression. It is the Target configuration for the Middle East seawater desalination project.

5. EBARA (Japan)

An energy-saving nozzle that can start at a low pressure of 0.1 MPa, specially designed for low-power emergency cooling after disasters in Japan. The static and dynamic pressure dual-channel structure ensures that the drift rate is less than 0.0005%.

6. Howden (UK)

The aviation fuel nozzle technology was applied to the cooling tower, with an adjustable atomization Angle of 120°, suitable for high return air and high humidity conditions. 100% repurchase on the Beihai oil and gas platform.

7. Seagull Shares (China)

Unique "three-splash" ABS nozzle, resistant to 80 ℃ high temperature without deformation. In the first phase of the Three Gorges Ulanqab Data Center, a 95% water distribution coverage rate was maintained even at an inlet water temperature of 43 ℃.

8. Jinri Cooling (China)

In 2024, a "tool-free" snap-on water distributor will be launched, increasing installation efficiency by 70%. It has been exported to steel mills and cement plants in 35 countries along the Belt and Road Initiative.

9. Liangji Industrial (Taiwan, China)

Having been deeply rooted in Southeast Asia for 40 years, its "petal" nozzles have remained unclogged for five years in the high-dust nickel-iron plant in Indonesia. Unique PP+GF composite material, resistant to ultraviolet aging for 10,000 hours.

10. Seagull (Turkey)

The logistics hub spanning Europe and Asia enables it to deliver DN600 super-large diameter water distributors to any port in Europe within 48 hours. The patented "Sea-Guard" coating can withstand salt spray for 3,000 hours and is the preferred choice for projects along the Red Sea coast.

From the North Sea of Scotland to the Jinko factory in Vietnam, from the post-disaster emergency machine room in Japan to the Atacama Desert in Chile, every technological iteration of the water distributor is reshaping the efficiency boundaries of cooling towers. Power Tower Industry Co., Ltd.  Being able to firmly hold the second place in this global race is attributed to a profound understanding of the humid and hot working conditions in Asia, the rapid delivery of 4.0 smart factories, and the killer application of "8-minute quick disassembly". In the next five years, with the popularization of AI computing power, liquid cooling and dry combined systems, water distributors will also undertake the complex task of multi-media coupling of "water-air-fluorine", and the top ten list will continue to roll. The only certainty is that whoever can make every drop of water fall in the right place will win the next cooling revolution.
