1. Manufacturing Process

• Fully Welded Plate Heat Exchanger
  Manufactured by TIG or laser welding, the plates are sealed through welding joints without using gaskets or filler materials. The welded seams provide both strength and tightness, making it suitable for high temperature and high pressure conditions.

• Brazed Plate Heat Exchanger
  Assembled with copper or nickel brazing material, then heated in a vacuum furnace where the filler metal melts and bonds the plates together. It is lightweight and compact, but its performance is limited by the brazing material.
