Our agitators have a flexible, modular design and enable you to
tailor a mixing solution to your exact requirements. The agitator
range includes top-mounted units, with or without bottom support,
as well as bottom or side-mounted units. Modularity lend itself to
ease of installation and maintenance, and superior design ensures
quality, performance and economy. The purpose-built agitators have
smooth surfaces that promote optimal flow.
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.

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.
