Pasteurizer controller MRF-2-PA2


 

Can be configured using the
WELBA “KONSOFT”
configuration software

The MRF-2-PA2 pasteuriser controller is used to control heaters, valves, agitator motors, etc. in tank pasteurisers. It controls programme sequences for the pasteurisation of milk and the production of cheese, cream cheese, quark, yoghurt, etc.

You can choose between four fully automatic programmes or operate the pasteuriser manually. The programmes can be freely configured.

Both installation and operation are kept very simple.

 

Features:

  • Four fully automatic programmes (freely definable)
  • Temperature control via either 2-point or PID
  • Power levels adjustable for different batch sizes
  • Freely definable temperature profiles
  • Agitator activity freely adjustable for each control phase
  • Digital input for optional remote start
  • Completion signal at end of programme
  • Alarm signal in the event of a sensor fault
  • PC-programmable via RS-485 interface
  • Service function for testing agitators and valves, etc.
  • Temperature profile can be logged (via WELBA-Konsoft)
  • Simple operation via various operating levels
