Customized Solutions

Our mixers are suitable for biogas, agricultural or industrial plants and can be operated electrically or in the agricultural sector by tractor/PTO.

Our products are designed to optimize the conditions in your biogas tanks resulting in improved output.
Ideal conditions for propagating methane bacteria are between 98.6 F and 107.6 F.

Both our rod agitators and submerged systems facilitate optimal temperature distribution throughout the tank. Optimal conditions lead to higher process stability and biogas production.
Additionally, SUMA agitators ensure fermentation as well as distribution of nutrients and vitamins for the supply of microorganisms.
Our standard products are used at pH levels between 5.5 and 8.5. Contact us for special applications.
Our constantly growing team of experts takes pleasure in providing the best solutions for your requirements.

Made in Germany

Our in-house engineering department develops and designs all agitators. Our own state of the art testing facility provides empiric data on propeller performance which is used to optimize geometries.
The flow simulations can also be used for planning your future plant and for establishing the best possible positioning of the agitators.
Furthermore, the engineering department supplies data sheets including installation information on request, with the aid of this data it is possible to get important information about the products in advance.
Customer support is our top priority. SUMA engineers are involved in every project and work closely with your project managers to accomplish the best possible solution. Nothing is left to chance – from drafting first plans through finalizing the technical solution and through production to installation.
