Forced Draft Dry Fluid Cooler Vs. Induced Draft Dry Fluid Cooler
Feature | Forced Draft Cooler | Induced Draft Cooler |
Fan Position | On the intake (inlet) side | On the discharge (exit) side |
Air Movement | Pushes air through the coil | Pulls air through the coil |
Air Distribution | Can be less uniform (potential for dead zones) | Highly uniform across the coil |
Fan Motor Environment | In cool ambient air | In hot discharge air |
Maintenance Access | Easier (on accessible, cool intake side) | Can be more difficult (in hot airstream) |
Air Recirculation Risk | Higher (low-velocity discharge) | Lower (high-velocity discharge) |
Weather Exposure | Coils on positive pressure | Coils on negative pressure |
