Introduction

The Alfa Laval ALT is a top-mounted agitator with free

hanging shaft for hygienic mixing and blending in atmospheric

and pressurized tanks. Its versatile, modular and hygienic

design enables customization to meet the requirements of

virtually any duty and ensures cost-effective, energy-efficient

operation. Exceptional cleanability through Cleaning-in-Place

makes the ALT agitator ideal for use in sterile and aseptic

applications. An ATEX-certified version is available for use in

potentially explosive environments.

Standard design

The Alfa Laval ALT top-mounted agitator consists of a drive

unit with optional bearing frame, free-hanging shaft with

special shaft seal, and one or multiple specially designed

energy-saving impellers (EnSaFoil) with two or three blades.

The Alfa Laval agitator range includes top-, bottom- and side

mounting models.

Working principle

The Alfa Laval ALT top-mounted agitator has an electrical

drive motor that transmits the energy required for mixing and

blending, either directly or via a gearbox, to the agitator shaft.

The shaft rotates, turning the EnSaFoil impellers. The impeller

movement creates a high flow with low shear due to the highly

effective axial pumping effect on the liquid in the tank. This

results in effective mixing and blending of the entire contents

of the tank.
