Energy-efficient agitators deliver optimal product quality while reducing operational costs and environmental footprint
Agitators keep products homogeneous and prevent sedimentation. They play an essential role in protecting product quality and uniformity. Alfa Laval agitators feature EnSaFoil (energy saving foil) propellers, which deliver lower energy consumption and gentler product treatment.
Specially designed for tank use, EnSaFoil propellers are wider in the middle and narrower at the tips. They produce an even pumping force that requires less energy and create less heat. Their design also ensures radial flow, with efficient product exchange across the tank.
Reduce energy consumption by up to 80% and lighten your environmental footprint
EnSaFoil propellers pump liquids four times more efficiently than standard pitched-blade propellers. As a result, energy consumption is reduced by up to 80% compared to standard equivalents. With today’s energy prices, the impact on operational costs can be significant, and you are ensured a short payback time on your investment. Reducing energy consumption also lowers CO2 emissions, helping you to lighten your environmental footprint and achieve your sustainability targets.
Ensure optimal product quality
By reducing the amount of energy that is required for stirring, the EnSaFoil propeller avoids creating too much heat in one part of the liquid. This is important because excessive heat can lead to product degradation. The EnSaFoil propeller also allows a lower rotational speed, keeping shear stress to a minimum and ensuring gentle product treatment. This helps preserve the quality of products such as milk, since agitation that is too vigorous can break down the fat structure of the cream.
Protect microbiological food safety with easier cleaning
Alfa Laval agitators are conceived with cleanability in mind. Cleaning does not require vessel entry by operators, and the propeller is designed to avoid shadow areas, protecting microbiological food safety. With simpler cleaning, Alfa Laval agitators also support operator safety, while saving maintenance time, water and energy.
Increase productivity by lowering processing time
The more efficient action of the EnSaFoil propeller enables producers to reduce processing times, by up to a factor of 8.
“Tank manufacturers often create tanks with the agitators built in. These agitators are typically marine-style propellers. Alfa Laval agitators are specially designed for tank dynamics, and as a result deliver energy savings with gentler product treatment. Alfa Laval agitators are modular and easy to install. Retrofitting an Alfa Laval agitator in one of your tanks will allow you to test the benefits and calculate the potential energy savings across your plant.”
