The tote tank mixers CR-M are designed for operation on stainless steel containers with filling openings of DN 400 mm and mixing volumes from 400 l up to 1,500 l. Depending on the viscosity of the mixing material, CR-Ms with fast running or gear reduced drives are available. The agitator shafts are connected to the drive shafts with sleeve couplings or borne within the gear’s hollow shaft (worm gear). The agitator shafts are balanced for concentric run after assembly. The mixer is mounted on the container’s manway lid, which is clamped with butterfly screws or a clamp ring. The manway lid is supplied by the container manufacturer or by the customer. The impellers are designed to fit through the filling opening DN 400 when being inserted. The electric container mixers are delivered with on-/off-switches with low-voltage breaker. The electric container mixers can also be supplied with frequency converter drives. All CR-M series mixers can be supplied as follows:

The tote tank mixers CRP-E are equipped with a pneumatic drive. It has been especially designed for plastic IBCs with filling openings of at least 150 mm and volumes from 600 l up to 1,200 l. The fast running pneumatic agitators are equipped with bearing and coupling housings. By means of the maintenance unit, pressurized air is enriched with oil for the vane drive. The mixer is mounted on a container traverse bridge, which is included in the scope of supply and clamped with a rapid fixing system to the cage frame of the IBC. The plastic bulk of the container is therefore not harmed by any static or dynamic loads by the agitator. Folding propellers that fit through the filling opening DN 150 mm are used for geared agitators. The agitator shafts are connected to the drive shafts with sleeve couplings or borne within the gear’s hollow shaft (worm gears). The agitator shafts are balanced for concentric run after assembly. Explosion-proof mixers are also feasible.
