Product Description
The energy-saving streisal Biobull fermenter agitator
Maximum circulating rate in concrete and steel tanks
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.
Constantly high agitating performance
With the agitator shaft installed at an inclined angle and two propellers mounted at different heights, the agitators generate significant hydraulic performance with horizontal and vertical flow components. The substrate can flow in without obstruction because the agitating elements are not covered by any obstructive built-in components.
Lowest self-generated power consumption
The propeller geometry with its three-dimensional profile has been optimised in the fluid mechanics laboratory; this and the large propeller diameters combined with low speeds of rotation mean the agitators / mixers generate maximum thrust while drawing very little power. As a result, energy and operating costs are significantly lower!
Serviceability
Important wearing parts are mounted externally and are therefore easy to access for maintenance and servicing.
High reliability and service life
The streisal Biobull has been available on the market for 20 years, and the first models are still in use. This means we can truly validate its long service life!
