Chuok Secer, ur Mnaanto Tharmlnoi representative, called ;n you laat week ooneemlng your usage of Tharmlnoi m-1 heat transfer fluid. Hr. sagar ralatad that tha Tharmlnoi PR heat ing ayetana are uaad to heat vaaaala for tha manufacture of ehemloala that go Into eoamatloa and food wrap plaatielzar. Tha Tharmlnoi PR-1 haat tranafar fluid praaantly In use In your heating ayataa eontalna polychlorinated biphenyls (PCBe). Aa you are undoubtedly aware, the PCB concentration In our anvir-nmant la under tha ecrutiny of varloua governmental agenelaa and aolentlfio research laboratories. In some studies, certain PCBe have been found to be a persistent environmental contaminant, and possibly. Injurious to certain forms of bird, aquatic and animal life. Accordingly It Is very Important that pCBs be kept out of >ur food ahaln. Specific applications where the use of Thermlnul PR fluids should definitely be avoided arc systems In volving food or food related products, animal feed, pharmaceuti cal produeta, packaging materials involving any if these items, and buildings where any of theca Items are manufactured or atored. Inasmuch as your Tharmlnoi |R system la used to manufseture pro ducts that goe Into food packaging and cosmetics, we mum* seek an laaaedlate change to a non-PCB containing haat transfer fluid. we have two fluids, Tharmlnoi 55 and Tharmlnoi 66, that would be conversion candidates for your hasting system. If memory aervea me correct, you ere using an 8 million BTU per hour lellpse heater with fluid outlet temperatures between 56o*F and 590*P. Because of these higher temperatures I would recommend Therminol 66 ac the beet pocalblc replacement fluid for Therelnol PR-1. Therminol 66 haa fluid stability to 650*P and would provide a long useful life In this heating aystam. MQNS 092342 -2- Should you change to Thermlnol 66 Before December 1, ]9 rl we wilt offer thla product at 22^/lb. roB Anniston, Ala. In addition we would provide free disposal of the Thermlnol pr-i fluid now m the Installation. This disposal would Include freight for the quantity of fluid returned to ;ur Sauget, 111. plant. Should you decide In favor of Thermlnol 55, a 575*1* fluid t > replaoe PR-1, we can offer this product at ro^/gall>n FOB Alvin, Texas. Again, we would provide free disposal of the Therein 1 PR fluid In the system and pay return freight to >ur Sauget, Illinois plant. Nalthar Thermlnol 55 nor Thermlnol 66 are classified ae fire resistant hast transfer fluids. Consequently, you mey wish t' consider the use of protective devices to minimise any addad fire risks. Wa suggest that y >u oonsult with the Insurer ,f y >ur property relative to thla matter. Again, lat me stress the urgency toward 0hanging from the PCB containing Therein-1 PR-1 fluid as public awareness of the PCB problem la Increasing. Should you have any questions mi Thermlnol 55 or 66 or n the conversion from Thermlnol PR fluids, please feel frea to con tact alther Chuck Sager In Akron at P.o.
