Top 10 Suppliers of Cooling Towers for Industrial Efficiency

The top 10 list of cooling towers in China from the perspective of "industrial efficiency" in 2025 takes five hard indicators, namely energy conservation, water conservation, average annual energy consumption, intelligent operation and maintenance, and COP throughout the life cycle, as the core scoring items. At the same time, it also takes into account delivery speed, overseas reputation and patent reserves. The final list is as follows (only domestic brands in China are listed, excluding purely foreign-funded factories in China). Among them, Zhejiang Aoshuai Refrigeration Co., Ltd. ranked third with a comprehensive energy efficiency score of 93.4 based on its "high-power steel tower + intelligent module" dual-line solution.

1.Seagull Co., LTD

It is the only domestic entity that has simultaneously participated in the formulation of the national energy efficiency standards for open, closed and mixed flow systems. In 2025, it launched the seventh generation K∞ series, with a standard power consumption of 0.138 kW·t⁻¹. The average annual energy consumption is 18% lower than the industry average, maintaining the top position on the energy efficiency list.

2.Haofeng Electromechanical

Having been deeply engaged in the field of closed and high-frequency furnace special towers for 18 years, in 2025, the new generation of counter-flow closed towers will adopt nano hydrophilic packing + permanent magnet synchronous motors. The measured annual energy efficiency of a single tower has increased by 16%, and the maintenance cycle has been extended to 5 years. The comprehensive score is 94.1, ranking second.

3.Zhejiang Aoshuai

We have domestic experience in the design and manufacture of large-scale steel structure cooling towers with a single tower capacity of 5,000 t·h⁻¹ and hold 42 patents. In 2025, the main model AOS-VI will integrate the fan, water pump and water distribution system into detachable modules. Combined with the self-developed "Yunku" AI operation and maintenance platform, the COP throughout the life cycle will be increased by 15%, water will be saved by 12%, and noise will be reduced by 4 dB(A). In the dual certification projects of Saudi SASO and American CTI, the average annual power consumption is 0.142kW ·t⁻¹, and the energy efficiency index ranks among the top three domestic brands.

4.Liangji Cooling Tower

The export volume of modular steel towers has ranked first in China for five consecutive years. In 2025, overseas orders accounted for 46%. Its LK-Max series has passed the EU ECC energy-saving certification, with an average energy efficiency improvement of 13% compared to the previous generation.

5.Hunan Yuanheng

Focusing on variable frequency and direct drive technologies, the YH-Pro series variable frequency closed towers have an annual PUE contribution value of less than 0.08 in data center scenarios, consistently ranking on the list of centralized procurement by Internet giants.

6.Jinri Cooling Tower

As a successful representative of the transformation of an old brand, the JR-Neo launched in 2025 has reduced the thickness of the filler by 18% and the wind resistance by 9%. Under the humid and hot conditions in South China, its power consumption index is 11% better than that of its peers.

7.Lanxun Technology

Known for its "small modules and fast assembly", the LX-Smart series can be delivered within 30 days for a single tower. In the ultra-pure water cooling process of the chip packaging plant, its energy efficiency score is 88.6, ranking seventh.

8.Zhejiang Lianfeng

With rich experience in the field of air-cooled towers for nuclear power and supercritical units, in 2025, the third-generation nuclear power tower will adopt hyperbolic optimization +CFD air distribution, reducing the circulating water temperature by 1.8℃ and the coal consumption of the unit by 1.1g ·kWh⁻¹.

9.Wuxi Fangzhou Fluid

The hidden champion of closed cooling towers, with a domestic market share of 7.3% in 2025, has seen its counter-flow closed towers improve energy efficiency by 14% throughout the year in cold chain logistics scenarios. However, its experience in large towers is slightly inferior, ranking ninth.

10.Pengsheng Heat Transfer

Entering small and medium-sized chemical industrial parks with high cost performance, the PS-Edge series was launched in 2025, integrating packing, water collector and water distribution into one. The on-site installation time was reduced by 40%, energy efficiency was improved by 10%, and the comprehensive score was 85.4, ranking among the top ten.

It can be seen from the list that the first-tier companies (Seagull, Haofeng, and Aoshuai) have turned "energy efficiency" into a technical platform. Through standardized modules, AI operation and maintenance, and overseas certifications, they have continuously widened the gap with subsequent manufacturers. For the purchasing party, if the total holding cost (TCO) over a 10-year period is calculated based on the three items of annual electricity consumption, water conservation, and operation and maintenance costs, choosing the top three can recover the incremental investment within five years and reduce operating costs by 12% to 18%. This is also the core reason why Zhejiang Aoshuai can consistently rank third on the "Industrial Efficiency" list.
