Horizontal agitator

Spiralo®

Patented and developed in collaboration with universities: The Spiralo® moves more material with the same energy input, even with viscous substrates.

Horizontal agitator

Schwanko

Made for fluctuating fill levels: the Schwanko immerses gently to conserve power and mixes substrate with low and high TS content.

Horizontal Agitator

Hydromixer

Our proven classic: the Hydromixer breaks up floating layers with large paddle blades, ensuring stable processes.

Long shaft agitator

Type Helix

The Spiralo® taken further: The Type Helix brings the suction effect with two rows of paddles all the way to the edge areas of large containers.

Long Shaft Agitator

Schwanko Type

Reach meets flexibility: As a long shaft agitator, the Schwanko prevents floating and sinking layers at any fill level.

Long Shaft Agitator

Type Hydromixer

Full power for large containers: The long shaft agitator Hydromixer mixes high total solids content with maximum circulation capacity.

Vertical Agitator

Vertical Agitator

Compact design, powerful performance: Our vertical agitators mix from top to bottom and prevent deposits on the bottom.
