This Australia industrial air cooler project involved installing a V-type multi-fan air cooler for outdoor heat rejection beside a modular plant-room area. The site required careful crane access, controlled lifting and accurate positioning within a narrow equipment corridor between the building and retaining wall.
The V-type industrial air cooler is lifted over the prepared equipment area using the designated lifting points.Australia industrial air cooler project overview
The photographs document the key installation stage: a large V-bank air cooler is lifted from the delivery area, moved over the site boundary and lowered onto the prepared concrete foundation. Multiple axial fans are arranged along the top of the unit, while the V-shaped coil configuration provides substantial heat-transfer surface within a compact footprint.
The unit was positioned next to a containerized plant or control-room module. This arrangement required the installation team to coordinate crane reach, lifting height, landing clearance and worker access without damaging the coil faces, fan sections or nearby structures.
Why a V-type air cooler fits a constrained site
A V-type industrial air cooler places two finned-coil banks at an angle, creating a large heat-transfer area while limiting the equipment footprint. Axial fans move ambient air through the coils and discharge it vertically, allowing heat to be rejected without a continuously operating evaporative-water circuit.
- Compact arrangement: the V-bank geometry provides coil area without requiring a very wide single horizontal bundle.
- Closed process loop: water, glycol or another selected process fluid remains inside the coil circuit.
- Multiple fan sections: the configuration can support staged or variable-speed operation when included in the control design.
- Outdoor installation: the structure, coils, fans and electrical components can be specified for the local environment.
- Reduced routine water demand: a fully dry unit avoids continuous spray-water consumption and water treatment.
Crane lifting and site coordination
Large air coolers must be lifted using the equipment manufacturer’s approved lifting points and a site-specific lift plan. The rigging arrangement should keep the unit stable and prevent loading on coil headers, fan guards or sheet-metal panels. Crane capacity must be checked against the equipment weight, lifting radius, boom configuration and ground condition.
At this Australian site, the unit was raised above the adjacent structure and guided into the narrow installation zone. Workers remained at controlled positions during landing and helped align the frame with the prepared foundation. The process required clear communication between the crane operator, dogger or rigger and the installation team.
The installation team positions the multi-fan air cooler beside the modular plant room and checks final alignment.Airflow and layout checks
Air coolers require an unobstructed path for intake and discharge air. Buildings, retaining walls, screens and nearby equipment can reduce airflow or allow warm discharge air to return to the coil inlet. Before commissioning, the project team should verify the actual clearances against the approved layout and confirm that the vertical fan discharge remains open.
For this installation, the unit’s position beside the building and sloped site boundary makes airflow review especially important. Coil cleaning access, fan and motor service space, safe walkways and future lifting access should remain available after piping and cable installation.
Mechanical and electrical completion
- Level and anchor the supporting frame according to the approved foundation drawing.
- Support connected piping independently so nozzle loads are not transferred into the coil headers.
- Install vents, drains, expansion provisions and freeze protection appropriate to the selected fluid and climate.
- Check fan rotation, guards, fasteners, vibration and motor electrical protection.
- Confirm temperature sensors, fan staging or VFD signals, alarms and control-panel communication.
- Inspect coil fins and clean construction debris before startup.
Commissioning priorities
Commissioning should begin with the design fluid concentration, system flushing and air removal. The team should confirm flow rate, entering and leaving fluid temperatures, coil pressure drop and fan response. Operating readings can then be compared with the selected design condition while checking for vibration, unusual sound, leakage and hot-air recirculation.
Where several fans are installed, controls should be tested across full and partial load. Staging or speed control can help maintain the required outlet temperature without running every fan at maximum speed when ambient temperature or process load is lower.
Engineering value of the project
This Australian air-cooler installation demonstrates that equipment selection and site installation must be considered together. Thermal performance alone is not sufficient: crane access, foundation position, surrounding structures, airflow, piping loads, electrical integration and long-term maintenance access all influence the reliability of the completed system.
For a similar project, review the ACHE heat exchanger selection guide. If peak dry-bulb conditions require additional capacity, HACST can also compare a fully dry unit with an adiabatic cooling system on the same operating basis.
