Alfa Laval ALTB Top-mounted Agitators

Introduction

The Alfa Laval ALTB is a top-mounted agitator with shaft and

bottom support 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 ALTB agitator ideal for use in

sterile and aseptic applications.

Applications

The ALTB top-mounted agitator is designed for a wide range

of tank mixing and blending duties across the dairy, food,

beverage, brewery, personal care, biotechnology and

pharmaceutical industries.

Benefits

• Versatile, modular, hygienic design, impellers with standard

pitch

• Can be configured for minimum energy consumption

• Gentle product treatment

• More uptime and higher yields due to low maintenance

requirements

• Meets EU and US standards and regulations such as

EHEDG, USDA, FDA, 3-A Sanitary Standards

Standard design

The ALTB top-mounted agitator consists of a drive unit with

shaft, shaft seal, bottom steady bearing (shaft support inside

the tank), and specially designed energy-saving (EnSaFoil)

impellers with two or three blades. The bottom steady bearing

extends agitator service life and reduces cost. The Alfa Laval

agitator range includes top-, bottom- and side-mounting

models.

Working principle

The Alfa Laval ALTB 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, supported by the shaft support, 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.
