Experience unmatched mixing efficiency with the Alfa Laval top mounted agitator ALTB. This agitator type ALT, also known as alt agitator or agitator type ALTB, is specifically engineered for superior flow rates and gentle product handling. Its versatile modular design and flexible mounting options make the agitator easily customizable for diverse hygienic applications. Improve mixing quality, performance and reduce energy and maintenance costs across industries such as dairy, beverage, personal care, chemical and pharmaceutical with this top mounted agitator.
Alfa Laval ALTB Application
Our top-mounted agitator with bottom support ALTB provides the same solutions as the ALT but with greater mechanical freedom. Depending on the size of the agitator, a bottom support may yield a more cost-effective solution. The Alfa Laval bottom support is designed to be sanitary and easy to clean.

ADVANTAGEOUS AND PROFITABLE DESIGN
Operation features
- Low energy consumption: The wide range of high efficiency propellers and drive units makes it possible to design for low operational costs
- Gentle product treatment: The wide range of high efficiency propellers makes it possible to design for low shear operation
Hygienic features
- Connections inside the tank (risk zones) can be avoided: Propellers can be welded onto the shaft
- Good drip off properties: No plane surfaces or grooves on internal parts
- Easy cleaning: No interior shadow sides between the blades and smooth surfaces
Maintenance features
- Easy bottom bearing replacement: Wear bushings can be replaced without dismantling the agitator drive
