Common Threats to Air Cooled Heat Exchangers
Exchanger Fouling
Limited cooling is an indication of exchanger fouling. This can result in reducing the cooling capacity of the exchanger, leading to a throughput reduction. This can also cause products heading to storage tanks to be too hot or other
process impacts.
High Vibration and Bearing Temperature
Increasing motor or fan vibration and bearing temperature can result in belt and coupling failure or can cause fan blades to stop, reducing the cooling capacity of the exchanger and throughput reduction. Other process, safety, and environmental impacts can occur as well.
Louver Mechanical Defects
Faulty louver position can result in restricting airflow and cooling capacity reduction, leading to overall throughput reduction and other potential process impacts.
