Project Case Study: Delivering Reliable Air Coolers for Iraq’s Refinery Expansion
Located in a tropical desert climate zone, Iraq frequently experiences extreme ambient temperatures exceeding 50°C in summer, accompanied by year-round severe sandstorms. This harsh natural environment poses rigorous challenges to the heat dissipation of refinery equipment:
-
Extreme Scarcity of Water Resources: In the Middle East desert, traditional cooling media (such as water cooling) cannot be adopted due to water shortages and cost constraints. The refinery processes must rely entirely on air cooling.
-
Severe Environmental Erosion: Standard air cooling equipment running in such high-temperature and sand-heavy environments is highly susceptible to drastic thermal efficiency degradation and severe wear on fan blades.
Consequently, the client demanded the highest international industrial standards for the structural strength of the air cooler units and the durability and driving power of the air cooler fan systems.
Customized Technical Solutions by Datang Finned Tube
Faced with such a demanding operating environment, Datang Finned Tube leveraged its profound technical expertise in finned tube manufacturing, pressure vessel design, and fluid dynamics simulation. The engineering team utilized comprehensive simulations to tailor a complete air cooling system for the Iraqi refinery.
1. Ingenious Design of Air Cooler Tube Bundles and Structures
To maintain the target temperature of the refinery processing media even under extreme ambient temperatures of 50°C+, Datang utilized its self-developed, high-heat-transfer bimetallic finned tubes as the core heat exchange components of the air cooler. The base tubes are made of high-quality carbon steel seamless pipes, and the outer layer is tightly wound or extruded with high-thermal-conductivity aluminum fins, vastly expanding the heat transfer area per unit length. Meanwhile, the overall steel framework features a heavy-duty anti-corrosion and dust-proof design, effectively avoiding local wind resistance and sand accumulation, thereby extending the service life of the entire machine.

2. Precise Matching of High-Efficiency and Weather-Resistant Air Cooler Fans
The cooling performance of an air-cooled heat exchanger largely depends on the controlled airflow passing through the tube bundles. To this end, Datang configured customized large-diameter, low-noise, and high-pressure air cooler fan assemblies for this project.
-
Advanced Material Selection: The blades of the air cooler fan are made of aviation-grade high-strength aluminum alloy or specialized composite materials, coated with an anti-erosion layer to perfectly withstand the severe desert sandstorms in Iraq.
-
Power & Smart Control: The fans are driven by Variable Frequency Drive (VFD) motors, which automatically adjust the speed of the air cooler fan according to the massive temperature difference between day and night. This ensures optimal cooling output while minimizing energy consumption.

Quality Inspection of Air Cooler Fans and Tube Bundles
Throughout the entire manufacturing process, Cangzhou Datang Steel Pipe Co., Ltd strictly implemented the ISO9001 quality management system and the internationally recognized API 661 standard (Air-Cooled Heat Exchangers for General Refinery Service).
To withstand the rigorous journey of long-distance maritime transit and overland desert transportation, Datang’s logistics team applied heavy-duty steel strapping and moisture-proof wrapping to every single air cooler framework. Meanwhile, the precision air cooler fan blades and VFD motors were independently secured within fully enclosed, fumigation-free wooden cases to guarantee absolute protection against salt spray, humidity, and physical impacts.
As the massive trucks laden with our air cooler units depart our facility and the containers filled with air cooler fan assemblies are seamlessly packed, we demonstrate not only Datang’s robust supply chain capability but also our solemn commitment to “on-time, top-quality delivery” for our global clientele!
