The cooling system is necessary to cool the latent heat of produced sandwich panels. Each sandwich panel is stood horizontally and move.
The latent heat is different with sandwich panel’s thickness but if the sandwich panels are stacked without this process, the temperature of the surface will be risen and bring post-deformation through shrinkage and expansion. This is one of the reasons of why some sandwich panels have waved surface.
To prevent damage on the sandwich panels, it has PVC belt driving system and guard.
