Distillation; Overfill Preventer In Still (Optional Equipment); Emission-Free Still Rake Out; Water Separator /Safety Separator - BÖWE P25 Instruction Manual

7 Functional Units

7.14 Distillation

The distillation unit consists of the still with ascending pipe and condenser.
The still is steam or electrically heated and equipped with an overfill preventer (optional equipment) and
still rinser. The still and the sight-glass are rinsed each time the still is pumped out. You can turn the
distillation heater on and off with 13E.
For information on still stripping and maintenance, see Point 11.

7.14.1 Overfill Preventer in Still (Optional Equipment)

A built-in sensor interrupts the pumping process when the upper edge of the view-glass has been
reached. The horn sounds and the diagnostic message E 6425 is displayed. Delete the diagnostic
message with the "C" button. The display shows "par 21". Push the "START" button to pump excess
solvent to Tank I. The program continues.

7.15 Emission-Free Still Rake Out

(Optional equipment)
If you have an economy filter, you can only perform the emission-free still rake out
if you have not precoated with filter powder. With each distillation pump out process, the sludge pump
pumps out the entire contents of the still.
Use maintenance program P36 for the emission-free still rake out.

7.16 Water Separator /Safety Separator

The distillation and recovery rates can be observed at the flow sight-glasses at the
water separator inlet.
The water phase from the water separator flows continually to the safety separator.
The solvent flows to the clean tank through a fixed pipeline.
The safety separator is protected against overfilling with a sensor.
If the level reaches the sensor, a horn signals and the alarm indication E0320 appears on the display.
The program continues running. You can delete the E0320 message by pressing "C".
