Alfa Laval ALTB

Alfa Laval agitators ALT top-mounted no bottom support

The Alfa Laval agitators ALT are characterized by the shaft that does not need bottom support. This makes it easy to get at everything inside the tank for inspection, cleaning and maintenance. Because there are no fittings in the bottom of the tank, the Alfa Laval agitator ALT is usually the chosen solution when hygiene standards have the prime focus. The ALT design features a robust support mounting fitted outside the tank. The special design of this shaft support frame, with a detachable shaft and internal coupling, eliminates any hygiene problems with a coupling inside the tank. It makes both installation and maintenance quicker and easier.

Alfa Laval agitator ALTB top-mounted with bottom support

The shaft used in the ALTB agitators is supported inside the tank by a steady bearing at the bottom. Despite this the Alfa Laval agitator ALTB is less expensive than comparable agitators with no shaft support inside the tank. Alfa Laval ALTB agitators have the advantage that the operating forces of the agitator unit are shared between fittings at the top and bottom of the tank. This makes this design ideal if there is only limited space available above the tank. A drive shaft with a smaller diameter can be used.

Alfa Laval ALTB agitators are available with two types of bottom support. The BS1 for when long bush service life is a prime concern. The BS2 with especially easy cleaning is applicable for when high hygiene standards are important.

ALS side-mounted agitator

Alfa Laval ALS agitators are side-mounted units which are widely used in storage tanks and silos. They are often used for low-viscosity products and for keeping the product inside the tank homogeneous. These units are notable for being a cost-effective design. It is easy to install and has exceptionally low maintenance and operating costs.

ALB bottom-mounted agitator

Alfa Laval ALB agitators are specifically designed to be mounted onto the bottom of the tank. This means the upper part of the tank does not need to be built to bear the weight of the agitator unit, paving the way for savings on both purchase costs and installation costs for the tank. An additional benefit is that a bottom-mounted agitator can be operated – as well as inspected and serviced – from ground level and therefore saves on time and manpower. Alfa Laval ALB agitators can also be fitted with a special sanitary-quality sterile seal for high-pressure applications and aseptic use.
