Use of mineral oil:

Lately we have experienced a number of problems with mineral oil, particularly in R717 plants. The problems can be divided into two groups:

a. The oil changes viscosity within a few operating hours.

b. The oil decomposes (becomes very black) within a few operating hours. The problems have been seen with several oil brands and have resulted in severe consequences

for 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:

To determine the code number, first refer to the Oil recommendation diagram for the refrigerant and compressor type and then plot the proposed operating conditions.

Example (recip. compressors):

Note: 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 require

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.

  Refrigerant: R134a

  Condensing temp. TC +35°C

  Evaporating temp. TE -3°C

Oil changing intervals

A 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. It is strongly recommended to monitor the quality of the oil by carrying out oil analyses with regular intervals. This will also give a good indication of the condition of the plant. T

  In case of a new plant. Very suitable.

  In case you wish to change from mineral oil

  a Max oil concentration in liquid phase at: TE: 2% W

  b Max oil concentration in liquid phase: contact Sabroe Refrigeration

  c Min suction temperature -50°C: at TE< -50°C superheating must be introduced.

Dry expansion systems only. Flooded systems to be considered individually: contact. Sabroe Refrigeration SH Suction gas superheat, K (Kelvin) L Zone in which both oils are useable M Calculation must be performed using COMP1
