Agitation Technology

Not every agitator
fits every plant.

Tank geometry, substrate, dry matter content, filling level, and installation situation place different demands on the agitation technology. That is why we develop various systems – and design them to match the respective plant.

Whether it is a paddle agitator, long-shaft agitator, or vertical agitator: each of our biogas agitators is designed for a specific task in the digester, secondary digester, or digestate storage.

Selection Guide

Which agitator fits
your plant?

Three questions about the tank, substrate, and operating conditions. The results will show which of our agitators are suitable for your plant.

Empfehlung7 Systeme

This recommendation does not replace a technical design. We evaluate the tank, substrate, and operating conditions together with our engineering team.

Custom Design

Standard doesn't fit?
Then we will develop it further for you.

Not every plant can be optimally mixed with a standard solution. That is why we adapt existing systems or develop individual agitator solutions for special tank geometries, substrates, and operating conditions.

Engineering

Not just built.
Designed.

The right agitation technology does not start with the product, but with the plant. That is why we consider the tank, substrate, and operating conditions together and develop the appropriate solution from them.
