Energy Efficient Low Shear Agitator Low Shear Agitator with a Superior Impeller Design The Rotofoil is a low shear agitator for mixing miscible liquids and dissolving solids that do not form fisheyes. The Rotofoil is also used for mixing when the purpose is to prevent sedimentation, enhance heat transfer, maintain floc circulation and keep liquids homogeneous. It is ideal for viscosities up to 5,000 cps. The Rotofoil has been used for years across various industries including food and beverage, pharmaceutical, cosmetic, chemical/coatings, water treatment and fat in water emulsions. Low energy consumption high versatility The design of the Rotofoil impeller blades makes a highly efficient mixer that provides uniform flow across the length of the impeller blade with low turbulence. Therefore, energy consumption is very low compared to the flow provided. Custom made: Adapted to each application and environment Mixing products at high temperature/pressure: Double mechanical seal and adaption of mounting flange Mixing corrosive products: Parts in product contact can be Titanium, SAF or PTFE coated AISI 316 L Mixing in sterile environment: Aseptic designed seals and electopolished surfaces Mixing in explosive environments: Explosion proof gear motor, ATEX approved seal, etc. Your Mixing Technology Partner

Hydrodynamics – the key to lower energy costs Axial Mixing with Energy Savings Just like a wing of an airplane, a mixing impeller creates turbulence from the back of the impeller blades if their angle at the front is too steep. Turbulence provides no agitation but draws a lot of power and uses energy. The hydrodynamic Rotofoil transmits almost all consumed energy to move liquid, and only a minimum will be wasted on turbulence. This table shows an example of an actual mixing job performed by a pitch blade turbine, a marine type propeller, and a Rotofoil. Pitch Blade Turbine Marine Propeller...
