Semi-Welded Line

Industrial semi-welded gasketed plate heat exchangers are used when gaskets are not suitable as one of the process media. Semi-welded GPHEs can also take a higher design pressure compared to fully gasketed plate-and-frame heat exchangers.

In the Semi-welded heat exchanger, the refrigerant flows in laser-welded, sealed plate channels, and in the opposite channel the liquid flows in gasketed channels.

Applications:
- Evaporators
- Condensers
- Desuperheaters
- Cascade duties
- Economizers/subcoolers
