Industrial Air-Cooled Heat Exchanger (ACHE)
Engineered for reliable heat rejection where water is limited
HACST industrial air-cooled heat exchangers (ACHEs) transfer heat from process fluids directly to ambient air through finned-tube bundles and axial fans. They provide a practical, low-water solution for industrial facilities that need dependable thermal performance, flexible installation and straightforward maintenance.

DESIGN & CONSTRUCTION
Configured around your process duty and site conditions
Each unit is engineered around the required heat load, process fluid, design ambient temperature, available footprint and maintenance access. The modular arrangement makes it easier to match a single cooler or a multi-bay system to the plant layout.
- Finned-tube bundles: tube and fin materials can be selected for thermal performance, fluid compatibility and corrosion resistance.
- Robust headers and structure: carbon steel or stainless-steel headers and an industrial steel frame support dependable long-term operation.
- Serviceable layout: accessible fan, bundle and platform arrangements help simplify inspection and routine maintenance.
WHY CHOOSE AN ACHE
Built to reduce water dependency without compromising process control
Control energy use
Axial fans can be paired with VFD control to match airflow to real thermal demand and reduce unnecessary fan power.
Adapt to changing capacity
Modular bays and bundles support practical expansion, phased installation and integration into new or existing facilities.
Support demanding sites
Materials, bundle arrangement and access provisions can be specified for industrial environments and project requirements, including API 661 when required.
ENGINEERING OPTIONS
A specification that works with your plant—not against it
The right ACHE depends on more than cooling capacity. HACST reviews thermal duty, process conditions, local climate, noise limits, power supply, automation requirements and service access before confirming the configuration.
Thermal design
Heat load, approach temperature, process fluid and design ambient conditions define bundle performance.
Fan & control
Axial fan arrangement, motor selection and VFD strategy are matched to operating and turndown requirements.
Materials & protection
Header, tube, fin and coating choices are considered for fluid chemistry, atmosphere and corrosion exposure.
Site integration
Footprint, transport limits, access platforms, structural interfaces and controls can be planned with the project team.
TYPICAL APPLICATIONS
Suitable for industries that need dependable air-side heat rejection
ACHE systems are particularly valuable where water is scarce, water discharge is restricted, or a plant needs a low-maintenance alternative to cooling-water equipment.

START WITH THE RIGHT DATA
Four inputs that help us size your ACHE correctly
- Define the thermal duty.Share heat rejection capacity, inlet and outlet temperatures, flow rate and process-fluid details.
- Confirm the design environment.Identify the location, summer ambient condition, altitude, dust or corrosive exposure and available power.
- Review the installation constraints.Provide available footprint, lifting and transport limits, noise considerations and maintenance clearance.
- Align controls and project standards.Specify automation interfaces, preferred fan-control strategy and any applicable project or API requirements.
