What is a Semi-Welded Plate Heat Exchanger?

A semi-welded plate heat exchanger (PHE) is a hybrid design combining the principles of gasketed and fully welded plate heat exchangers. In this configuration:
● One fluid path is fully welded (typically for aggressive or high-pressure media).
● The other fluid path uses gaskets (for easier maintenance and non-corrosive fluids).
This design offers a balance between the sealing reliability of welded plates and the maintenance flexibility of gasketed plates.
