Efficient and safe
System solutions by Stelzer Rührtechnik for the generation of biogas in waste water treatment plants, plants based on renewable sources from nature and mechanical-biological systems using municipal waste as base material, bioethanol and biodiesel.
- Slurry storage
Bioethanol & biodiesel
- Enzyme and yeast fermentation
STELZER Rührtechnik is the right contact when new methods for biogas systems and renewable energy production matter. We do not just use standard solutions but consequently apply individual adaptations and further developments that put our agitators ahead of competing products.
We have extensive process and agitator knowledge, for example in second-generation bioethanol production or modern fatty acid ester processes for biodiesel. We design and produce highly efficient axial and counter-current flow impellers with optimised low shear rates according to individual specifications. The agitators ensure very gently product treatment and are available as top or side-entry agitators. Agitators may be implemented with free overhung shafts without bottom bearing, which avoids maintenance in the tank. Side-entry agitators have reliable drive and sealing systems and can on request be equipped with fast change device to replace seals on a full tank.
