Milk temperature regulator MRF-M2 - NEW


 

parameterizable with the configuration software
WELBA „KONSOFT"

Milk temperature regulator in flat display housing
PC programmable !

(Front panel mounting, super flat)

The microprocessor-controlled milk cooling temperature regulator MRF-M is used to control agitator motors and refrigeration compressors on milk cooling equipment.

  • Easy operation via three work levels
  • 2 freely selectable target temperatures
  • Various "intermediate agitating" functions
  • Option of switching to “Permanent agitating”
  • Automatic subsequent agitating
  • Various "cooling start delay" variants can be set:
    • Time Lag
    • clocking
    • time-delayed and clocked
  • Digital input - can be used for various functions:
    • Remote start cooling
    • External temperature changeover
    • External compressor lock
    • Anti-icing protection when there is little filling in the tub
      (e.g. for calf feeding...)
    • Compressor fault monitoring
    • "Milk cooling tub lid" safety switch
  • Alarm in the event of sensor short-circuit/sensor fault
    (adjustable relay switching state in event of fault)
  • Emergency cooling function in the event of a sensor fault
  • Compressor sway protection
  • PC-programmable via RS-485 interface
  • Data logger (temperature profile and occurrence can be called up via KONSOFT for up to two days)
  • Service function for testing agitator, compressor and digital input
  • Automatic parameter storage without data loss when a power-cut occurs
