AL Series agitators from Alfa Laval offer mixing solutions to meet many requirements in food, dairy, beverage, pharmaceutical, biotechnology, and cosmetic applications. AL agitators can be sized for several applications for both atmospheric and pressurized tanks and can be configured for use in sterile/aseptic applications.
There are four configurations available to best suit your application needs:
Top mount (ALT)
Top mount with bottom support (ALTB)
Bottom mount (ALB)
Side mount (ALS)
To ensure the best possible device for your specifications, each application is evaluated carefully. This allows proper sizing, optimized power consumption, and the lowest possible pricing for each agitator.
ALT
Alfa Laval’s top mounted agitator ALT offers mixing solutions to meet any requirements in food, dairy, beverage, pharmaceutical, biotechnology and cosmetic applications. Type ALT agitators can be sized for several applications for both atmospheric and pressurised tanks. Configuration for use in sterile/aseptic applications is also possible. Sizing and customising the agitator to the specific task ensures optimised power consumption and pricing.

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.
Simplified service
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.
Product range
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.
