Functional principle

Mixing for highly viscous media.

The central agitator ensures effective mixing at fluctuating filling levels, even with highly viscous media. It protects the bacterial population and optimizes the gas yield. Low-maintenance, durable, and ideal for digesters and secondary digesters with tank sizes up to 27 meters.
Technical Data

Designed for your tank.

The characteristic values result from tank geometry, substrate, and operating conditions. The values shown are guide values – the specific design is carried out together with our engineering team.
