  • the evaporation tray is preferably constructed without partitions. This is a free convection of the water within the evaporation tray if, then disturbed relatively little. In addition, several evaporation trays can be stacked better.
  • the transition region or the depression Due to the transition region or the depression additional vertical heat transfer surfaces and thus improved convection may result, which may increase the water circulation within the evaporation tray.
  • the circulation of water can help transfer more heat to the evaporation tray, allowing the water molecules to dissolve faster from the heated water surface, increasing the evaporation capacity of the evaporation tray.
