How to Select the Right Air-Cooled Heat Exchanger

🔧 Why Choose an Air-Cooled Heat Exchanger (ACHE)

In industries where water resources are limited — such as refineries, petrochemical plants, or power stations —
an Air-Cooled Heat Exchanger (ACHE) is the ideal solution.
It uses ambient air as the cooling medium, reducing water consumption, chemical treatment costs, and environmental impact.

📊 Key Factors to Consider When Selecting an Air-Cooled Heat Exchangers

1. Process Fluid Properties

   • Consider inlet and outlet temperatures.

   • Identify the fluid type (e.g., hydrocarbon, gas, oil, water).
     Proper material selection for tubes and fins ensures durability and corrosion resistance.

2. Ambient Air Temperature and Site Conditions

   • Hot climates or dusty environments can affect cooling performance.

   • Choose suitable fan types and fin configurations to optimize efficiency.

3. Installation Orientation

   • Horizontal Type: Ideal for open areas with large space.

   • Vertical Type: Suitable for compact sites or when upward air discharge is required.

4. Fan Arrangement

   • Forced Draft (Fan Below): Best for high-temperature fluids.

   • Induced Draft (Fan Above): Provides better air distribution and minimizes hot air recirculation.

5. Maintenance Accessibility

   • Design should allow easy access for fin cleaning, bearing and motor inspection.

   • Tube bundles should be removable for repair or replacement.
