Fermenter agitator

For highly-specialised fermentation processes

Fermenter agitators for bioreactors

Fermenter agitators are indispensable for the manufacture of pharmaceuticals, vaccines, vitamins, fermented beverages and new food products. The use of micro-organisms for the production of a wide range of products has become indispensable in the pharmaceutical, biotech and food industries.

Thanks to these special agitators, a uniform homogenisation of the process media and optimal mass transfer at the phase boundaries are achieved in bioreactors. This efficiency is crucial for the success of the fermentation.

The highly-specialised fermentation processes are as diverse as the possible applications and require the precise consideration of numerous parameters. For this reason, we offer a comprehensive selection of fermenter agitators, which are precisely matched to the respective process requirements by our engineers.

Top quality, maximum efficiency and optimal yield

Powerful fermenter agitators for special bioreactor requirements

Fermenter agitators for bioreactors provide optimal solutions for specific requirements such as specific power input, tip speed and the mass transfer coefficient (kLa value). Each fermenter agitator is precisely engineered to the requirements of the respective bioreactor to guarantee high yields at a consistently high quality. With a mixing volume of up to 350,000 litres, our agitators provide maximum efficiency and reliability.

Our fermenter agitators also meet the highest standards in terms of hygienic design and offer maximum flexibility. For example, versions with a double-acting mechanical seal are available, as are hermetically-sealed systems with magnetic couplings up to a torque of 1,300 Nm.
