The central component of the Sauter Biogas System is of course the sprinkling nozzle (ESD). Depending on the diameter of the tank, one to four nozzles are distributed in a circle from the outside to the tank, in each case together with a sight glass.

This allows us to reach almost the entire surface of the fermentation substrate in the tank with the irrigation jet. A floating layer problem, as with stirred systems, we do not know, the ESD from our patented system of sprinkling instead of stirring! is the solution, by the way also in repowering.

"Sprinkled, not stirred!" - Here you can see the effect of the sprinkling jet inside the fermenter. The (patented) spirngling system requires no agitators and no biomass bunker for solids addition. In addition, the system is suitable for a very wide range of feed materials.
