Slow-running large-propeller agitators of the Biobull® type enable large quantities of fluid to be circulated in tanks with largely constant fill levels. They are used above all in biogas generation and in other applications with difficult substrates (fibrous constituents, maximum dry matter contents, etc.). The maximum medium temperature is 60 °C. By means of an external agitator column, the agitator can also be used in steel tanks of different shapes and sizes: The forces and moments are not transferred to the tank wall, but into the foundation.

High and adjustable stirring performance Great hydraulic thrust which can be adapted to the biological condition of the substrate / mixing task by means of a height adjustment. Unhindered substrate inflow. no shadowing effect from interfering fixtures. The large diamter of the propeller hub and -blade virtually eliminates the build-up of layers in this critical area.
