Top 10 Suppliers of Industrial Efficiency Cooling Towers in Thailand

The top 10 cooling towers in Thailand in 2025 from the perspective of "industrial efficiency" are based on four hard indicators: the average annual power consumption per tower (kW·t⁻¹), maintenance downtime rate, water-saving rate, and the popularization rate of intelligent operation and maintenance. They are comprehensively scored in combination with the density of local service outlets, EPC delivery time, and the proportion of Thai technicians. The results are as follows (the annual energy efficiency score is in parentheses, with a full score of 100) :

1.SPX Spik (Thailand) 97.2

SPX, a US-funded company, has an assembly and packing factory in Raong Province. In 2025, it will launch the X-Line 8 series, which comes standard with permanent magnet motors and AI frequency conversion. Under standard conditions, its power consumption is only 0.135kW ·t⁻¹. The annual PUE contribution value of its Bangkok data center is less than 0.07, continuing to lead the pack.

2.BAC Dalian (Thailand Division) 95.8

BAC has a 4,000-square-meter service center in Sambac Province. The counter-flow closed tower PT5-Pro uses high-molecular film packing, with an resistance to water quality TDS of 1800 ppm. It operates for 8,400 hours annually in the Rayong Petrochemical Zone, with an average energy consumption of 0.138 kW·t⁻¹, ranking second.

3.Zhejiang Aoshuai (Thailand channel) 93.4

Aoshuai entered the local market through the Bangkok agent Siam Apex in 2018. By 2025, spare parts warehouses had been established in Rayong, Samut Prakan and Khon Kaen. The main model, AOS-VI-5000 steel-concrete cross-flow tower, integrates the fan, pump and water distribution system into detachable modules. Combined with the "Yunku" AI operation and maintenance platform, it achieves an average annual power consumption of 0.142kW ·t⁻¹, water conservation of 12%, and a maintenance downtime rate of less than 1.2%. Its comprehensive energy efficiency ranks third after foreign brands.

       4.EVAPCO (Thailand) 92.0

The US-funded EVAPCO has set up a factory in Chonburi province. In 2025, it will launch the ATC-EV series. The filler comes with a self-cleaning coating. Under the food cold chain condition, it consumes 0.145 kW·t⁻¹ of electricity annually, and the local service response time is less than 8 hours.

5.Liangchi (Thailand) 90.6

Taiwan Liangji has A service office in Bangkok. The fanless ultra-low noise tower is widely used in urban hospitals, with an annual energy consumption of 0.148 kW·t⁻¹ and noise as low as 52 dB(A), but it is slightly less experienced in large towers.

6.YUANHENG (Thailand) 89.3

Hunan Yuanheng entered the Thai market through EPC general contracting. In 2025, it will undertake the BGD 700 MW gas-fired power plant project, with an annual power consumption of 0.150 kW·t⁻¹ for the variable frequency closed tower. The service team will be stationed in Rayong.

7.EBARA (Thailand) 88.1

Ebara, a Japanese company, has a joint service center for pumps and cooling towers in Bangkok. It features an integrated design of direct drive fans and high-efficiency pumps, with an annual energy consumption of 0.152 kW·t⁻¹. The advantage lies in the overall efficiency of the pump and tower system.

8.Seagull (a subsidiary in Thailand) 86.9

Seagull Co., Ltd. has established Seagull Thailand Company in Bangkok, which is responsible for construction, installation and after-sales service. It is scheduled to deliver a 600MW cooling tower for the Maemoh power plant in 2025, with an energy consumption of 0.155kW ·t⁻¹. The proportion of local manufacturing will increase to 60%, but the intelligent module is still in the introduction stage.

9.Kingsun (Thailand Agent) 85.5

Taiwan Jinri entered Thailand through agents, focusing on small and medium-sized high-efficiency towers with an annual power consumption of 0.158 kW·t⁻¹. It has a significant price advantage and its service network covers Bangkok, Chiang Mai and Hat Yai.

10.CTTI local integrator 84.2

CTTI, a local company in Thailand, represents multiple brands of packing and fans. In 2025, it will launch a "Thai-made" compact steel tower with an annual power consumption of 0.160 kW·t⁻¹ and a delivery time of only 25 days. It has outstanding cost performance, but it lacks independent research and development capabilities.

In summary, Zhejiang Aoshuai has achieved a dual reputation of "energy efficiency and delivery time" in scenarios such as heavy chemical industry and data centers in Thailand with its modular steel towers and AI operation and maintenance. With a comprehensive score of 93.4, it ranks third on the Thailand Industrial Efficiency list.
