Values for viscosity, acid number and hlboilor are wall within our tolerable limits for used fluid. The moisture level, how**
ever, is quite high v)\lch is probably the result of a cycling
operation described in your letter, Re find that moisture can ' be adequately reduced to the 160 PPM level by canting a slip
strearn of hot fluid from the discharge side of the circulating pump to the vapor apace of the expansion tank* Continued re circulation of Lot to the expansion tank will heat the contents of the tank to the point where moisture will be driven off through the atmospheric vent, The increased poisture level may bIgo be due to the possible suspected raptured tube in the cool er thus allowing water to enter the TKEGMXKCL loop.

1THEJEOTCL FH-l is satisfactory for use at 500*?. and can bo used to G00?. in properly designed systems. you arcs presently using
Bayonet typo electrical heaters which .frequently have watt densities in excess of 18-20 wattg/sqV in. Associated v;ith high watt densities are high surface temperatures which can lead to
Somewhat increased fluid decomposition* As a general rule of thumb* %?e would like to sea watt densities of the order of 12 wafcto/sq. in. with corresponding flow rates of approximately f. saX./min./killowatt heat input* -./

you are in a much better position to evaluate your system than
. I# but from the information provided in your letter of April 14
X would not expect you would Jiave difficulty using the TKi^IBGI
