TECHNICAL DATA

Engine
Engine size and speed vary according to the requirements of the work. IEC engine IP55 is used by standard; other types are optional.  It is RAL5010 painted as a standard.

Voltage and Frequency
3x380, 420V, 50Hz and 3x440V, 480V, 60Hz are the standards. All engine voltages and frequencies are available.

Threads
Various thread types are available according to the configuration. Normal synthetic or mineral oil is used as a standard. Optionally, oil approved for food applications, as a standard RAL5010 painted.

ATEX - option
Agitators can be supplied with a declaration of compliance with 94/9/EC directive for use in an ATEX environment.

Ordering
The following information is required when order to ensure correct dimensions and configuration:

1- Tank geometry
2- Product specifications
3- Task of the agitator
4- Please request a demand form to choose the correct agitator.


Standard Design
Alfa Laval bottom-mounted propeller agitators series is designed to address all needs of the customers. With its modular structure, agitators can be designed for all types of applications in hygiene and food industry. Modular structure has been designed to address the European and American hygiene standards and directives, such as EHEDG, USDA, FDA, 3A, etc 



Configurable Design
ALB type agitator design can be configured using the following components.

• Drive units (drive unit + shaft support + shaft diameter)
• Gasket installation (oil holder + shaft gasket type)
• Shaft (length)
• Energy Saving Propellers (propeller type + surface quality)





Advantageous and Profitable Design
All configurations bring significant advantages with are given in the examples below:









  OPERATING SPECIFICATIONS

  ADVANTAGES

  Low energy consumption


  Propeller and drive units which ensure
  high efficiency with minimum energy allow
  designing for low operating costs.


  Slow Product Processing

  Specially designed propellers allow
  designing for low-speed operation.



  HYGIENIC PROPERTIES

  ADVANTAGES

  Easy external cleaning

  Sealing Gaskets and stainless steel seat
  body design (for washing)

  Connections inside the tank
  (contamination risk is eliminated) are
  canceled as an option.

  Flange connection drive shaft inside the  
  tank and special shaft connection
  Seat case and drive units

  Sealing components are automatically
  cleaned during operation

  Unique gasket installation with self-  
  washing sealing system

  Easy Cleaning

  There are no parts that cannot be cleaned
  or remain in the shadow between the
  wings.



  MAINTENANCE PROPERTIES

  ADVANTAGES

  All Maintenance procedures (Replacing
  shaft gasket seats, and other corroded
  parts) can be done outside the tank.

  Removable Shaft and seat case drive
  units can be demounted outside the tank
