Two step laminators YPSATOR VFF
VFF Process for Glass/Glass Modules or Panels for high capacities 180 – 250 MWp.
The Bürkle VFF-Process is a two-step lamination process utilizing a vacuum/membrane press in the first step and a double-sided heated flat press in the second step. A double-sided cooled flat press is used for cooling. The flat press allows uniform, parallel pressing and practically eliminates the “edge pinch” effect at the edges of the module, without using frames during lamination. The double sided heating ensures a faster lamination, homogeneously from both sides, and thus minimizing any remaining stress in the module after lamination.
