When to Choose Air Cooled Heat Exchanger
- Pick Air Cooled Heat Exchanger if:
- Water is scarce/expensive.
- Low-maintenance operation is critical.
- Process tolerates higher approach temps.
- Pick Water Cooled Heat Exchanger if:
- High cooling efficiency is needed.
- Water is readily available.
- Space is limited (e.g., urban plants).
Example Scenarios
- Oil Refinery in Desert: ACHE (no water, high ambient temps).
- Power Plant Near River: WCHE (high efficiency, water access).
- Chemical Plant with Corrosive Fluids: ACHE (avoid water treatment).
