PROPERTY Acid Number Moisture Viscosity 100* F* SAMPLE 0.96 mgKOK/gm 642 ppm 60.0 centipoise Mr* Padberg, the viscosity indicates there might be the possibility of contamination of the heat transfer liquid. Normal viscosities for new material are typically 65 ceatipoises. Our spec calls for & 73 cent!poise maximum* The 69 centipoise reading is unusually low. Further evidence that contamination is a possibility is the relatively high moisture content. Our spec calls for 59 parts pet- million msaimursa. Acid number* too* is high* with a spec limit of 9.01 maximum. oSNN 3A^2 STLCOPCB4083955 Mr. J. B* Fadberg June 17, 1%$ Page 2 Is It possible you have a leak ia your cooking oil to TKEBMINQL heat exchanger? Have you experienced any pumping difficulty considering the high moisture content of the THERMlftQL sample ? I recommend you send an additional sample as soon as possible so we cam confirm these results as either a temporary situation or a continuing one.
