Customer satisfaction through quality

Since the foundation in 1957 were sold between 70,000 and 80,000 agitators. With our Head office in Sulzberg we operate internationally with an export share of 50%. Our plants can be found in 52 different countries. Despite the large internationality, we stand for quality and know-how.
The entire value-added chain is almost exclusively on site in Sulzberg.
With our products we guarantee a long service life and easy and quick maintenance.
This makes it possible to replace parts even after 10 years thanks to the modular design.

Solutions for each customer's requirements

Our mixers are suitable for biogas, agricultural or industrial plants and can be operated electrically or in the agricultural sector by tractor.
With our products we ensure that the milieu conditions are optimally positioned to achieve the highest possible output in your biogas tank.
With a temperature of between 37 and 42°C the best growth of methane bacteria takes place.
Through our long-axis agitators and submersible motors the optimal temperature distribution in the tank is reached. This leads to a higher biogas yield and guarantees high process stability.
In addition, the fermentation and the distribution of nutrients and vitamins to the supply of micro-organisms are ensured by agitating with the SUMA agitators.
You can use our products at pH-values between 5.5% and 8.5% within the fermenter.
60 employees and 10 apprentices are working on your desired requests to implement and generate solutions for a wide variety of challenges for nearly 60 years.
