Use of mineral oil:
we have experienced a number of problems with mineral oil, particularly
in R717 plants. The problems can be divided into two groups:
The oil changes viscosity within a few operating hours.
The oil decomposes (becomes very black) within a few operating hours.
The problems have been seen with several oil brands and have resulted in
both compressors and plants. When using mineral oil, it is thus
important that the plant is monitored very closely, that oil samples are
taken regularly (every 1-2,000 hours) and that the condition/colour of
the oil is checked on a weekly basis.
How to use the oil recommendation diagrams:
determine the code number, first refer to the Oil recommendation
diagram for the refrigerant and compressor type and then plot the
proposed operating conditions.
Plants may operate at different conditions from time to time, for
example at different evaporating temperatures due to plant variations or
at different condensing temperatures due to seasonal changes. By
plotting TC and TE in the oil recommendation diagram, this example would
a No 1 oil. If, however, TE changes at certain times, e.g. from -3 to +7°C, a No 2 oil should be utilised. But, as +7°C is inside the marked area, the No 1 oil can be utilised also at this TE.

Evaporating temp. TE -3°C
Oil changing intervals
list of the recommended intervals for changing the oil can be found in
the compressor instruction manual or by downloading a manual from your
compressor manufacturer. These are provided for guidance only. The
actual interval between oil changes will often be determined by a
variety of operating parameters within the plant.
