Box 3866 Omaha, Nebraska June 17. 1965 .... : JStl > -v Dear Mr. Carlsons Here ie the analysis results from your recent THERMINOL FR-2 sampler ?' : 5 \ ' ' - ; PROPERTY Acid Number Moisture Viscosity 100* F. SAM PUS 0* 10 mgKOH/gna 410 ppm 75 centipoise The fluid is in suitable condition for continued service. However, 1 would like to point out that the moisture content is unusually high. Our production specification calls for a maximum moisture limit of 50 ppm. Your 410 parts per million may indicate either a moisture contaminated sampling container, or the leakage of moisture into the system via water-cooled . bearing seals, leaking heat exchangers, or an excessive amount of moisture aspiration via the expansion lank vent line when your system is cycled frequently. Not being knowledgeable regarding your system, 1 suggest you look at the aforementioned as possibilities. Moisture can be detrimental since it will cause pump malfunction (cavitation) sad the consequent loss of flow through the heater with subsequent overheating of the fluid due to high film temperatures^ I suggest you submit another sample in two or three months. We will check the fluid then to ascertain its performance. lit me know when t can be of service, or contact our Fluide Specialist for your area, Mr. Raleigh Garcia (also located at the above address In St, Louis), Sincerely, S.
