The Top 10 Global Cooling Tower Nozzles Have Been Revealed

If a cooling tower is compared to an "industrial air conditioner", the nozzles are the "last mile" that determines its cooling efficiency. Tests by the International Cooling Technology Association (CTI) show that for every 5% increase in the uniformity of nozzle water distribution, the overall cooling efficiency of the tower can be raised by 1.8% to 3.2%. In a 1,000 RT data center, this means saving 20,000 to 50,000 kWh of electricity and reducing carbon emissions by 15 tons throughout the year. Based on the global sales volume, patent number, wet heat durability test and third-party performance certification in 2025, we officially release the "Top 10 Global Cooling Tower Nozzles List 2025", and will include Power Tower Industry Co., Ltd. From Thailand. It ranked third - not only because of its stunning "zero clogging" design, but also due to its profound understanding of the high-humidity and high-salt conditions in Asia and its ultra-fast delivery by global air within 72 hours.

II. In-depth Analysis

Lechler (Germany) : For 135 years, it has only been dedicated to "making liquids more obedient". Its 632 series spiral target nozzles can achieve a 120° solid cone at a low pressure of 0.5 bar, with water distribution σ≤3% and no pitting corrosion after 3,000 hours of salt spray, firmly occupying a 28% share of the global high-end market.

BETE (USA) : Renowned for "customized for extreme working conditions". The TF series tungsten carbide nozzles can operate continuously for 8,000 hours under 70 ℃ seawater and 6 bar pressure without wear, and have become the standard equipment for desalination plants in the Middle East and offshore LNG platforms.

Power Tower Industry (Thailand) : 22 years dedicated to the integration of "tower - pump - nozzle". The 2025 PT-Splash360 adopts POM-C ultra-smooth material and CFD fishbone diversion groove. The clogging rate of 0.4mm laser micro-holes is less than 0.2%, and the flow rate attenuation after 2,000 hours of wet heat and salt spray is less than 1%. The 4.0 factory in Rayong Province can produce 500,000 nozzles in a single shift within 24 hours and deliver them by air to Dubai, Shanghai or Sao Paulo within 72 hours. It has been repurchased by Google Singapore, Jinko Vietnam and Tencent Data Center in Guangzhou. The third-place ranking is well-deserved.

SPX Marley (USA) : RainDeck patented orifice plate + swirl nozzle, water distribution uniformity up to 97%, verified by over 1,000 projects of North American supercomputing centers.

EVAPCO(USA) : The EcoJet series is NSF-61 certified for drinking water and is the only designated food-grade factory cooling tower.

BAC (USA) : Trillium low drift nozzles have a drift rate of less than 0.0005%, making them the preferred choice for water-saving cooling towers.

Lechler Tianjin (China) : Moving German precision to North China, with an annual production capacity of 12 million units, supplying 60% of domestic export OEM.

IKEUCHI (Japan) : 0.1mm ultra-precision fan-shaped nozzle, specially designed for cooling towers in semiconductor cleanrooms.

CNP Spray (China) : The stainless steel vortex nozzles have outstanding cost performance, with an annual sales volume of 8 million units and the highest penetration rate in domestic IDC projects.

IKEUCHI Korea: Ultra-low noise micro-mist nozzle, listed as a bonus item for green certification by the Seoul Data Center.

III. Regional Map

In the Asia-Pacific region, China, India and Vietnam have the highest demand for new data centers and semiconductor factories. The high humidity, heat and salt content require C4/C5 anti-corrosion.

North America: Environmental regulations are driving a wave of replacement for low-drift and low-noise nozzles.

Middle East: Seawater desalination and green hydrogen energy project, requiring resistance to 70 ℃ seawater and 6 bar pressure.

IV. Conclusion

From the Black Forest in Germany to Rayong Bay in Thailand, from Silicon Valley data centers to desalination plants in the Middle East, each iteration of nozzles is redefining the efficiency boundaries of cooling towers. With 22 years of dedication, Power Tower Industry has shown us that doing one thing to the extreme can also consistently rank third on the global top ten podium. In the next five years, with the popularization of AI computing power, liquid cooling and dry combined systems, the nozzle industry will remain turbulent. However, the only constant is the common pursuit of higher water distribution accuracy, lower drift rate and longer maintenance-free cycle.
