Cincinnati, Ohio , February 20, 1939 Carbide & Carbon Chemicals Corporation, South Charleston, West Virginia-* Attention: Mr. R, C. Hostel-map. Re: 600 Kw. Bloc trie Dowtherm Heater ______ Negotiation R-15I~CI______ . Gentlemen: 7/e enclose specifications in-triplicate for the 600 Kw. heater, which you'are consider- ing, 1 ' . ' ' ' ' 1518 price of this heater,, in accordance with the specifications and outline Y-920044, will be $4,926,00 f.o.b. factory, Jeannette> Pennsylvania; without control., \ There are several featured ..in these specifications which will bo of interest.. Among j those . The.heater ribbon.Will be ,025rt thick. On the.original'heater the ribbon was Q04a thick and-for the replacement backet ,02rt. . This added thickness will result in exceptionally rugged construc tion. - . . . Tho manufacturer of the inaulating..material for the ribbon, sup port, as a result of further research, has recommended a different .,- material for this service. The trade name of this insulation is Marinite. It is constructed from asbestos material and-an inorganic " binder, and will be guaranteed for temperatures to 906*3?. It is also a better electrical insulation than Transits and-is comparable for mechanical strength. We,' therefore, adopt Marinite for this heater, ' : . -- . -. In designing the outer jacket, we have arranged the upper section so that the cover bolts on the heater can be reached with ft.straight open wrsnch and. socket wrehches will not be required* / The electrical terminals wi 11 be. constructed as shoita on drawing 2-930059. Our experi ments on the glass' covered' terminal have demonstrated that we can guarantee this type for current "loads"as high as 6D0 amperes.'. The rated current per terminal for- this heater is 395 amperes. We have, therefore* reduced the number of terminals to six'and ' the heating element will be connected in two'wye circuits, each Of 300 Kw. capacity.' The design of these electrical terminals permitd the removal of any of them without - removing- the shell head.' ' . .* ......
