Our agitators have a flexible, modular design and enable you to tailor a mixing solution to your exact requirements. The agitator range includes top-mounted units, with or without bottom support, as well as bottom or side-mounted units. Modularity lend itself to ease of installation and maintenance, and superior design ensures quality, performance and economy. The purpose-built agitators have impellers that promote optimal flow.
Excellent levels of hygiene for a wide range of cost-effective, tank-based blending and mixing duties
- Easily tailored to meet specific tank/process requirements – modular design with hygienic materials increases flexibility and optimizes operation
- Reduced energy consumption – unique impeller design and product heat absorption makes ALTB up to 400% more efficient than impellers with standard pitc
- Hygienic design and smooth surfaces meet EHEDG, USDA, FDA and 3-A standards
- Operates at low speeds without reducing pumping capacity – up to 80% less power consumption compared with conventional impellers
- High productivity – low wear and low maintenance (no dismantling or tank entry, for instance, to replace long-life seals and bearings)
We have versions for sterile/aseptic applications and optional equipment, including welding flange, blind flange, cover for motor/gear and spare part kit, for all ALTB top-mounted agitators. Material certificates are available on request.
How it works
Based on a modular design, our ALTB agitators consist of a drive unit with bearing frame, shaft with special shaft seal and specially designed energy-saving airfoil (EnSaFoil) impellers with two or three blades. The tripod support stand helps extend working life and reduce cost. An electrical drive motor transmits the energy required for mixing and blending (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.
ALB
The Alfa Laval ALB bottom-mounted agitator is suitable for atmospheric and pressurized tanks and comes in a range of sizes. The modular design and choice of size ensures an agitator fit-for-purpose so you won’t have to invest more than needed and can look forward to optimal power consumption. The ALB agitators are designed for easy CIP and can also be for use in sterile/aseptic and ATEX-certified applications.
ALS
The Alfa Laval ALS side-mounted agitator is suitable for atmospheric and pressurized tanks and comes in a range of sizes. The modular design and sizing options ensure an agitator fit-for-purpose so you won’t have to invest more than needed, enabling optimal power consumption. The ALS agitators are designed for easy CIP and can also be for use in sterile/aseptic and ATEX-certified applications.
ALT
The Alfa Laval ALT top-mounted agitator is suitable for atmospheric and pressurized tanks and comes in a range of sizes. The modular design and sizing options means you won’t have to invest more than needed and can look forward to optimal power consumption. ALT agitators are designed for easy CIP and can also be configured for use in sterile/aseptic and ATEX-certified applications.
ALTB
The Alfa Laval ALTB top-mounted agitator is suitable for atmospheric and pressurized tanks and comes in various sizes. The addition of a bottom support stabilizes the shaft and ensures reliable operation. The range of sizing optaions means you can look forward to optimal power consumption. ALTB agitators are designed for easy CIP and can also be configured for use in sterile/aseptic applications.
