Vertical agitator „Homer"

highest efficiency ensured by flow-optimised mixture.

The AAT agitator consists of two-optimised impellers in the bottom an ceiling area. On the one hand this produces an optimised flow from top to bottom, an on the other hand a circular movement is created.

The freshly fed substrate is mixed in the tank immediatley and creates perfect fermentation conditions and increases the output.

High-quality material and robust components make the vertical agitator of AAT into long-life raliable product.

By means of the frequency converter operation, the agitator is substrate-optimised and the energy consumption is reduced to a minimum.

The inside of the tank contains no wearing parts, and thus the tank must not be opened for maintenance.
