  • This working fluid now flows vertically through the built-in body, whereby it flows along the mat elements over its surface or drips off it.
  • this mat element is no longer exclusively vertical, but arranged obliquely to the vertical or has a plurality of oblique sections. The water flowing along these sections running obliquely to the vertical drips off the mat element and thus forms an enlarged surface which is exposed to the useful fluid passing through the installation body in countercurrent or crossflow.

  • the thickness extension As a thickness extension of a mat element, the distance between the highest elevation on the upper side of the mat element to the highest elevation on the underside of the mat element can be considered. In the case of a corrugated mat element, the thickness extension is therefore the vertical distance between the elevations and the depressions (valleys and mountains) plus the material thickness.
