TAN for Reolube Turbofluid 46 SJ

Squpek -
Reolube 46 SJ is a trixylphosphate based fluid. I find it difficult to believe that Chemtura (the manufacturer) would supply a material with a 0.14 TAN. Typically you should expect fluids of this type to be in the 0.01 to 0.04 range (in the drum). This raises a couple of questions.

Was the fluid sample that was analyzed taken from a new drum or from the unit?
If taken from the unit, was the unit properly flushed prior to loading with the Reolube product? Sometimes new equipment that is stored prior to commissioning will be filled with a "preservative" fluid which has a high TAN and must be rinsed out prior to filling with the intended operating fluid.

Typical OEM limits for operating fluids range from 0.2 mg KOH/gram to 0.5 depending on the equipment OEM.
Typical OEM limits for new phosphate ester fluids are never higher than 0.05 mg KOH/gram.

It would be unwise to begin operations with a 0.14 TAN fluid. Things can only get worse from that point.

What type of equipment are you using and where are you located.

I would suggest contacting Chemtura directly rather than dealing with your oil distributor. Data should be available on line.

Good luck
