Gasketed plate heat exchangers

Made of a frame that encloses, using suitable tie-rods, the assembled plates pack. The particular fishbone design with which the plates are pressed, creates between them, once assembled, two fully isolated channels, one for the hot fluid and one for the cold fluid, inside which the two media are distributed uniformly and flow in the opposite direction to each other. The corrugated surface of the plate causes high turbulence of fluids flowing inside the exchanger, improving heat transfer.

The plates are complete with rubber gaskets that ensure a perfect hydraulic seal of the exchanger even under pressure.

Among the advantages of gasketed plate heat exchangers, we have:
  • high heat transfer coefficient
  • no mixing between the fluids
  • flexibility (ability to adapt the exchanger to changed conditions by increasing the number of internal plates)
  • long-lasting durability, with the possibility of maintaining the exchanger through specific plates pack regeneration operations and / or replacement of the various components
