Description

 

The microprocessor control unit in the photo above meets the demands of the new German milk authority.

In connection with the recorder, WAL offers a complete add-on kit for all milk pasteurizers. It can also be fitted to new equipment and contains all necessary temperature and pressure sensors.

Each device prototype has been tested by the Federal Dairy Research Centre, Kiel and the acceptance tests that are carried out by official engineers in each German Federal State. In addition to the legally required monitoring functions, WAL offers further advantages for its complete solution:

  • replacement of the temperature control unit
  • one data chart
  • monitoring of all 4 pressure values
  • differential pressure control
  • integrated logic
  • start up control
  • monitoring of the outlet temperature
  • separate temperature selection during the cleaning process
  • display of the cream treatment
