Our Air Cooled Heat Exchanger Design & Engineering Capabilities
HTEPL provides air cooled heat exchanger design and engineering support based on process data, operating conditions, site requirements, and project specifications. Engineering considers both thermal performance and mechanical integrity to develop a configuration suitable for the required duty and installation conditions.
Thermal Design
Thermal design can consider:
- Heat duty
- Process fluid properties and flow rate
- Inlet and outlet temperatures
- Ambient design temperature
- Temperature approach
- Allowable process-side pressure drop
- Fouling considerations
- Heat-transfer surface area
- Airflow and air-side pressure drop
- Fan power requirements
These parameters help determine the tube bundle arrangement, finned surface area, airflow, fan duty, air-side performance, and exchanger configuration.
Mechanical Design
Mechanical design considerations can include:
- Design pressure and temperature
- Tube bundle construction
- Header configuration
- Nozzle size and orientation
- Materials of construction
- Structural frames and supports
- Fan and drive arrangement

The design can be developed according to applicable project codes, client specifications, and approved technical requirements.
Project-Specific Engineering
HTEPL can engineer ACHEs for new projects, replacement units, retrofits, and capacity upgrades. Engineering review can consider customer datasheets, EPC specifications, existing equipment details, nozzle locations, plot-space limitations, site conditions, prevailing airflow, and potential hot-air recirculation.
For replacement projects, the existing equipment footprint and process connections can also be considered to support integration within available installation constraints.
Types of Air Cooled Heat Exchangers
Air cooled heat exchangers are commonly configured as forced draft or induced draft systems. Selection depends on factors such as heat duty, process temperature, ambient conditions, airflow, plot space, and maintenance access.
Forced Draft Air Cooled Heat Exchanger
In a forced draft air cooled heat exchanger, fans are installed below the finned tube bundle and push ambient air through the heat-transfer surface.
Because the fans, motors, and drive components are located on the cooler air-inlet side, they are generally easier to access for inspection and maintenance. Forced draft arrangements may be selected where equipment accessibility, layout, and airflow requirements favour this configuration.
Induced Draft Air Cooled Heat Exchanger
In an induced draft air cooled heat exchanger, fans are positioned above the tube bundle and draw ambient air through the finned tubes.
This arrangement can provide more uniform airflow across the bundle and discharge heated air at a higher elevation. It may be preferred where airflow distribution, hot-air recirculation, plant layout, or process requirements are important considerations.
| Design Factor | Forced Draft | Induced Draft |
|---|---|---|
| Fan position | Below tube bundle | Above tube bundle |
| Air movement | Pushes air through bundle | Draws air through bundle |
| Fan inlet air | Cooler ambient air | Heated discharge air |
| Fan/drive access | Generally easier | Arrangement dependent |
| Airflow distribution | Application dependent | Can be more uniform |
| Selection basis | Process and site conditions | Process and site conditions |
Selecting the Right ACHE Configuration
HTEPL can evaluate heat duty, process temperature, ambient design temperature, pressure drop, airflow, equipment layout, maintenance access, and installation space to determine a suitable forced or induced draft ACHE configuration.
Air Cooled Heat Exchanger Technical Specifications
HTEPL manufactures air cooled heat exchangers to project-specific technical requirements rather than limiting customers to a fixed standard configuration.

Materials of Construction
The materials of construction for an air cooled heat exchanger should be selected according to the process fluid, corrosion potential, operating temperature, design pressure, environmental conditions, required service life, and customer specification. HTEPL can manufacture ACHE components in different metallurgies depending on the approved thermal and mechanical design.
| Component | Typical Material Options |
|---|---|
| Tubes | Carbon steel, SS304, SS316, copper alloys, or project-specific metallurgy |
| Headers | Carbon steel, stainless steel, or material specified for the process service |
| Fins | Aluminium, copper, or project-specific material |
| Nozzles | Selected to suit pressure-part metallurgy and project requirements |
| Structural Components | Carbon steel, coated steel, or project-specific material |
Carbon Steel
Carbon steel can be used for selected tubes, headers, nozzles, and structural components. It is suitable when the process fluid and corrosion conditions allow its use.
It is commonly used in industrial services that require good mechanical strength. The material should also be compatible with the process conditions.
Stainless Steel
Stainless steels such as SS304 and SS316 can be used where better corrosion resistance is required. They may also be selected to meet fluid or project-specific material requirements.
The final grade depends on the process fluid, temperature, contaminants, and corrosion conditions.
Copper and Copper Alloys
Copper and copper-alloy tubes can be used in selected applications. These materials offer useful thermal and corrosion properties.
Their suitability depends on the process fluid and operating environment. Material compatibility should be checked before final selection.
Aluminium and Copper Fins
Fins increase the external heat-transfer area of the tube bundle. This helps improve air-side thermal performance.
Aluminium and copper fins can be selected based on thermal needs, environmental conditions, corrosion risk, and customer specifications.
Fin Configurations
Finned tubes can use different fin configurations based on the operating conditions. Common options include L-type wrap-on fins, G-type embedded fins, and extruded fins.
Fin selection depends on the operating temperature, corrosion environment, thermal performance, and project specifications. The suitable fin type is selected during the thermal and mechanical design of the ACHE.
The final metallurgy of an ACHE should be confirmed during the engineering review. HTEPL can review the process fluid, design pressure, design temperature, corrosion requirements, existing equipment metallurgy, and client or EPC specifications before selecting the materials of construction.
Applications of Air Cooled Heat Exchangers
Air cooled heat exchangers are used to cool or condense processed liquids, gases, oils, hydrocarbons, and vapours. They remove heat from the process fluid and release it into the ambient air.
These exchangers are useful where cooling water is limited, expensive, or needs to be reduced.
Process Fluid Cooling
ACHEs can cool hot process liquids to the required outlet temperature. The cooled fluid can then move to further processing, storage, or other equipment.
Oil Cooling
Air cooled heat exchangers are used for lubricating oil, hydraulic oil, and industrial oil cooling. They remove heat produced during equipment operation.
This cooling can be achieved without a separate continuous cooling-water circuit.
Gas and Compressor Discharge Cooling
ACHEs can be used for compressors after cooling. They cool hot discharge gas before it moves to another process stage.
The cooled gas may then go to separation, storage, downstream processing, or another compression stage.
Design depends on the required gas flow rate, pressure, temperature, and cooling duty.
Hydrocarbon Cooling
ACHEs are used for hydrocarbon cooling in refinery, petrochemical, and oil & gas applications.
The design is based on the required thermal duty, fluid properties, and operating conditions.
Vapour Condensation
Air cooled heat exchangers can also be designed for vapour condensation duties.
Ambient air removes heat from the vapour and helps it condense. This can reduce the need for water-based cooling systems.
Equipment and Utility Cooling
ACHEs can be used in equipment and utility systems. They can cool circulating process fluids and auxiliary fluids used in industrial operations.
Cooling in Water-Scarce Locations
Air cooled heat exchangers use ambient air as the cooling medium. This can reduce the need for cooling towers and continuous cooling-water circulation.
They are therefore suitable for industrial sites where water supply is limited.
