VDA7000
Automatic Vacuum Distillation System
The Koehler VDA7000 Automatic Vacuum Distillations System performs reduced
pressure distillations of petroleum products, fully automated from the
Initial Boiling Point (IBP) to the detected or pre-selected Final Boiling Point
(FBP). Advanced Windows®-based software package allows continuous operation
at reduced pressure and atmospheric conditions, and the selection of
intermediate stops at pre-selected vapor or flask temperatures followed by
the continuation of the distillation analysis at various user-selected
reduced pressures. The distillate volume is automatically measured in a
temperature-controlled receiver, and the heat rate is automatically
controlled for a proper distillation rate. All test parameters are displayed during
the distillation process in real-time, including actual boiling temperature,
AET (atmospheric equivalent temperature), distillation rate, distilled
volume, distillation rate vs. yield, and vacuum pressure. Test results,
parameters and oil specific data are archived on the computer hard drive, and
easily printed to an external printer.
