What is the design of the Wave heat exchanger?


The Wave exchanger is composed of two 0,6 mm thick stainless steel plates welded together using an array of stamped pads which ensure a double function:

  • The rigidity of the exchanger

  • An even distribution of water circulating throughout the exchanger to avoid the formation of “hot spots”

This DualSun-specific design is protected by international patents.


The heat exchanger of the Wave panel is made of a grade of stainless steel whose expansion coefficient is very close to that of glass.

More precisely, it is the ferritic stainless steel KARA from APERAM.
