Rütten Magnetic Agitator




Why let the magnetic agitator in your sterile vessel you are cleaning your vessel and have residue in the bearing of your magnetic agitator? Take the magnetic agitator out with removal of your cover! Dismantle the magnetic agitator and clean all parts separately in your washing machine you already have available in your factory.

Magnetic-driven agitators flanged directly on the bottom of the sterile tanks pose frequent problems due to the difficulty of their reliable and proper cleaning with the existing CIP systems. As a result, "sterile dirt" accumulates on many critical surfaces of such agitators. Furthermore, due to their mechanical complexity, such units are quite expensive.

© Solution

Suspended at the central harvesting tube, interchangeable magnetic agitators are the best solution to magnetic agitation in sterile transfer vessels. Rütten Magnetic Agitators® equipped with double stainless-steel stirring bars suspended just above the vessel bottom. The separate magnetic drive rests on the ground and is easily moved.  The construction of these units is very simple and facilitates the quick disassembling for cleaning purposes. Such agitators are less expensive than the currently available bottom-flanged executions.
