Topic “Protection against icing“
The MRF-M2 basically offers three different options for preventing small amounts of
milk from freezing in the milk cooling tub:
- Cooling start delay (see section 7.7.1)
- Anti-icing protection by means of low pressure monitoring (see section 7.7.2)
- Anti-icing protection through external compressor shutdown (see section 7.7.2)
7.7.1 Different variants for cooling start delay
The regulator can be programmed to delay the start of the compressor after the
cooling mode has been triggered, to prevent a slight freezing of milk in the tank.
The regulator offers different variants of cooling start delays:
0.
no cooling start delay
Cooling starts immediately
1.
simple cooling start delay
Cooling starts after a set time.
2.
periodic cooling phases (Power reduction through clocking)
Cooling starts in the form of periodic cooling phases at set intervals
before then switching over to temperature regulation.
3.
periodic cooling phases after switch-on delay
Cooling starts after a set time, in the form of pre-set periodic cooling
phases at set intervals before then switching over to temp. regulation.
Cooling start delay is
set using parameters
[P61 - P65].
Cooling immediately temperature-regulated
