Vertical agitator „Bart"
Highest efficiency through level adjusted agitator blades. Our new developped vertical agitator has been designed especially for the use in hydrolysis tanks, buffer tanks with variable filling levels or direct in the digester.
The agitator consists of flow-optimised stirrer blades in the floor area and an automatic height-adjustable floating blade. On the one hand this produces an optimisted flow from top to bottom, and on the other hand a circular movement is created.
The freshly fed substrate is stirred into the tank immediatley and uniformly, and is kept homogeneous permanently. The floating blade reliably prevents the development of surface crusts.
High-quality materials and robust components make the vertical agitator of AAT into long-life and very reliable product.
By means of the frequency converter operation, the stirrer intensity is substrate-optimised energy consumption is reduced to a minimum.
