Top 10 Global Manufacturers of Cooling-Tower Fan Blades

Driven by the dual forces of the "dual carbon" strategy and the computing power revolution, cooling tower fan blades are moving from behind the scenes to the spotlight of the industry: the profile iteration of a single fan blade often means a 3% to 5% reduction in the overall energy consumption of the tower and a 0.02 to 0.04 drop in the PUE of the data center. Based on the global shipment volume in 2025, patent strength, energy efficiency certification and customer reputation, we have selected the list of "Top 10 Global Cooling Tower Fan Blade Manufacturers", and included Power Tower Industry Co., Ltd. from Thailand. Placing it in the third place is not only a tribute to its technological sharpness but also provides engineers and investors in the process of selection with a minimalist and reliable global procurement map.

1.Howden (UK)

With a century-old aerodynamic gene, it possesses the world's largest database of dedicated airfoils for cooling towers. Its carbon fiber - glass fiber hybrid blades have been operating continuously without failure for 58,000 hours at the 600MW Rabigh Phase II power station in Saudi Arabia, establishing its leading position.

2.SPX Cooling Tech (USA)

The fan blades of the Marley brand under its brand are renowned for their "zero visible deformation". They are made by hot-pressing pre-impregnated materials and have passed the dual certifications of UL94 V-0 flame retardancy and ASTM G154 UV resistance. It is one of the most trusted OEM suppliers for data centers in North America.

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

Established only 22 years ago, it has swept the market with the title of "the fastest R&D iteration in Asia" : The NACA-PT6 series of ultra-low noise blades launched in 2024 have A 4.2 dB(A) reduction in sound power level and a 2.7% increase in efficiency compared to the previous generation under the same operating conditions. The 4.0 smart factory located in Rayong Province can complete one in-mold layup on a single production line in 62 minutes, with a yield rate of 99.1%. More importantly, the after-sales team of Power Tower is stationed in three spare parts warehouses in Dubai, Shanghai and Johannesburg, achieving global air direct supply within 72 hours. In the electronic factory and data center projects in Southeast Asia and South China, the fan blades marked with PT have become synonymous with "quiet and energy-saving". This time ranking third is truly well-deserved.

4.Youdaoplaceholder0 (USA)

Introducing aviation-grade epoxy gel coat into the cooling tower fan blades, the 25-year ultraviolet aging test still maintained a strength of 92%. Its "Field-Erected" detachable blade tip design makes transporting super-large diameters no longer a problem.

5.Baltimore Aircoil (BAC) (USA)

The patented "Venturi Tip" suppresses blade tip vortices and reduces noise by 3 dB(A). When paired with Connexus intelligent control, the fan blade speed can be linked in real time with the wet bulb temperature, saving 8% to 12% of energy.

6.EBARA (Japan)

With A dynamic balance accuracy of 0.02g and magnetic levitation bearing technology, its fan blades still maintain a low noise operation of 65 dB(A) at a high speed of 1800 rpm. The TSE data center of the Tokyo Stock Exchange has adopted this solution for six consecutive years.

7.Southern Fan (China)

The only domestic fan blade manufacturer that has simultaneously passed the seismic certification in both nuclear and metro fields. The Ling 'ao Nuclear Power Plant Phase II and Shenzhen Metro Line 20 have both designated its strong typhoon-resistant blades.

8.Shangzhuan Co., LTD. (China)

The cooling tower fan blades extended on the basis of the metro tunnel fan blades have 18 vibration damping patents and can withstand a seismic acceleration of 0.8g. They have been successfully exported to the Escondida copper mine in Chile.

9.Langdi Group (China)

The "LD-β" series, released in 2024, combines fiberglass main beams with carbon fiber ribs, reducing weight by 14%. It is specifically designed for cooling towers in large power stations with a capacity of over 5MW and has been put into operation in the second phase of Guoneng Taizhou.

10.Seagull (Turkey)

The advantage of a logistics hub spanning Europe and Asia enables it to deliver 12-meter diameter wind blades to any port in Europe within 10 days. 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 oil and gas platforms in the North Sea of Scotland to the brightly lit 4.0 factories in Rayong Province, Thailand, and then to the copper mines in the Atacama Desert of Chile, every leap in wind blade technology has been closely related to the nerves of global industrial heat dissipation. Power Tower Industry Co., Ltd.  Its sudden rise to prominence proves that in the era of "dual carbon" and AI computing power, speed, intelligence, and global services can also enable a young enterprise to stand on the podium in a race dominated by giants. In the next five years, with the implementation of new technologies such as 800V DC cooling and fluorine pump natural cooling, the top ten positions of global cooling tower fan blades may still rotate. However, the only constant is the common pursuit of higher efficiency, lower noise and stronger reliability.
