| Feature | Brazed Plate (BPHE) | Gasketed Plate (PHE) |
| Construction | Permanently brazed together | Held together by large bolts and gaskets |
| Cleanability | Cannot be opened. Chemical cleaning only. | Can be fully opened for mechanical cleaning. |
| Gaskets | None. Eliminates leak points. | Yes. Potential for leakage and requires maintenance. |
| Pressure/Time | Higher pressure capability (~45 bar) | Lower pressure capability (~25 bar) |
| Cost for Repair | Must replace entire unit | Can replace individual plates or gaskets |
| Ideal Use | Clean, closed loops; refrigeration | Fouling fluids; frequent service required |
Brazed Plate Heat Exchanger is a sealed, high-performance, low-maintenance unit ideal for clean fluids where its compact size and high efficiency are paramount. Its inability to be cleaned mechanically is its most significant trade-off.
