When to Choose Which Type?
| Scenario | Recommended Type | Reason |
| Clean fluids (water, oils), moderate T&P, need for cleaning/inspection | Gasketed Plate (PHE) | Cost-effective, serviceable, and flexible. |
| High pressure/temperature, corrosive media, no fouling | Brazed Plate (BPHE) | Compact, sealed, and cost-effective for its duty. |
| Very high P/T, aggressive media, abrasive particles, high reliability | Welded Plate (WPHE) | Handles the most severe conditions while maintaining plate efficiency. |
| Extreme fouling, slurries with large solids, viscous fluids | Shell-and-Tube | Large flow channels are |
