The Fermenter Agitator Biosubstrator®

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.

Low energy consumption: High circulation power and outstanding efficiency due to the large diameter of the propeller and a very slow rotational speed.

Serviceability: Important wear parts are outside the fermenter and thus freely accessible for maintenance and service work, no regular opening of the tank cover. Contactless, wear-free sealing between stirring shaft and side wall.

Reliability / life time: The BIOSUBSTRATOR® features a very robust bearing bracket with grease lubricated bearings and an amply dimensioned, external stell structure. Vibration dampers at the hinge points absorb oscillation peaks and add to the long-life cycle of the agitator.
