Advantages of Induced Draft Design
| Advantage | Explanation |
| Better Air Distribution | The plenum chamber helps create a more uniform airflow across the entire tube bundle face, improving heat transfer efficiency. |
| Reduced Hot Air Recirculation | Because the fan discharges the hot air vertically at a high velocity, it is less likely to be sucked back into the air inlets, especially in multi-bay installations. This is a major operational advantage. |
| Easier Maintenance on Fan Drive | The motor and drive assembly are located on the top structure, making them more accessible for maintenance without needing to work directly under the bundle. |
| Protection for Mechanical Parts | The fan and drive are exposed to the warm, exiting air rather than the cold, often corrosive, ambient air. This can reduce corrosion and weathering of these critical components. |
| Handles Higher Air Temperatures | Since the fan is moving already-heated air, it is suitable for applications where the exit air temperature is high. |
