Fill fluid selection example
In an application that has a maximum process temperature of 284 °F (140 °C) and a
maximum pressure of 700 Torr, SYLTHERM
™
XLT would be recommended. However, say
the process pressure drops to 200 Torr and 284 °F (140 °C) at one point during the process
cycle, then Silicone 200 for vacuum applications would be recommended because it is the
fill fluid farthest to the right that the process falls into.
