Air Cooled Heat Exchanger

Air-Cooled Heat Exchanger

Product Overview

The Air-Cooled Heat Exchanger (ACHE) is a water-free cooling solution that transfers heat from process fluids to ambient air via finned tube bundles, driven by axial fans. It’s ideal for industries such as oil & gas, manufacturing, and power plants—particularly in water-scarce areas or sites where water use is restricted.

Construction & Compliance

Built with robust materials—carbon steel or stainless steel headers, copper tubes, and aluminum fins—this exchanger is designed for durability and corrosion resistance. Its modular configuration complies with API Standard 661, allowing scalability, easy installation, and routine maintenance.

Key Advantages

• Water-free operation eliminates water usage, treatment, and environmental discharge
• High modularity enables scalable capacity and flexible plant integration
• Low operational maintenance with corrosion-resistant components
• VFD axial fans enable precise airflow control and energy savings

Ideal Applications

Perfectly suited for industrial sites where water is costly or restricted, such as refinery cooling loops, process equipment, and power station auxiliary cooling circuits. Particularly advantageous in arid climates and regions with strict water use policies.

Operation & Control

Equipped with axial fans driven by VFDs to regulate airflow based on thermal demand. A control system monitors process fluid and ambient temperature, adjusting fan speed to minimize power usage. Maintenance is simplified thanks to easy access to coil sections and fan units.

How to Select

• Confirm the required heat rejection capacity (kW) and ambient design conditions
• Choose header and tube materials based on fluid compatibility and corrosiveness
• Size the modular units and fan capacities to match site layout and accessibility
• Ensure compatibility with automation systems (e.g., utilities, DCS) for fan/VFD control
