Our top mounted agitator with bottom support ALTB offers the same solutions as the ALT but with higher flexibility in mechanical design. Depending on the size of the agitator a bottom support may result in a more economical configuration. The Alfa Laval bottom support comes in sanitary design created for easy CIP.
Energy efficient design
Our EnSaFoil impellers, as well as our specially developed EnSaFerm impellers for fermentation use, reduce energy consumption and the absorption of heat by your product. Based on extensive fluid dynamic studies, their unique shape makes them up to 400% more efficient than impellers with a standard pitch. Besides minimizing energy loss, our impellers operate at reduced speeds without reducing pumping capacity. Compared to agitators with conventional impellers, they thereby lower agitator power consumption by up 80%.
Modular and hygienic
Alfa Laval agitators ensure excellent levels of hygiene for a wide range of blending and mixing duties in processing tanks. Modular design using hygienic materials with smooth surfaces provides great flexibility to tailor agitator systems to meet specific tank and process requirements, including EHEDG, USDA, FDA and 3-A standards.
Low wear and minimal maintenance are hallmarks of Alfa Laval agitators. This translates into higher productivity due to reduced downtime. No dismantling or entry into the tank, for instance, is required for parts replacement of long-life seals and bearings. This saves both time and money.
Four different Alfa Laval agitator models for top-, bottom- and side-mounting are available for installation in pressurized and non-pressurized tanks. Sterile/aseptic and ATEX-certified versions are available upon request.

How it works
Based on a modular design, Alfa Laval agitators consist of a drive unit with bearing frame, shaft with special shaft seal arrangement, and bi- or tri-lobe energy-saving airfoil impellers.
An electrical motor (drive unit) transmits the energy required for mixing and blending, either directly or via a gearbox, to the agitator shaft. The shaft rotates, turning the specially designed Energy Saving Foil impellers. The impeller movement creates a high flow with low shear due to thehighly effective axial pumping effect on the liquid in the tank. This results in effective mixing and blending of the entire contents of the tank.
Alfa Laval also offers agitator models for sterile/aseptic applications and optional equipment, including welding flange, blind flange, cover for motor/gear and spare part kit, for its range of agitators.
