Description
4.1 Field of application
The device is designed for vacuum control in the rough vacuum range in laboratories and in
industry during the conveyance of gaseous media. In particular, the device is suitable for ro-
tary evaporators of all kinds.
4.2 Function
The device consists of a
vacuum controller
(measurement/control device) and an
inte-
grated membrane vacuum pump
for vacuum processes. The control is done by inputting
parameters for "setpoints" and the querying of the "actual values". This enables the control
and monitoring of the vacuum processes in various operating modes:
Vacuum pressure control for the rough vacuum range - pressure range of
1100 mbar to
2 mbar
Vacuum pressure generation via the speed-controlled vacuum pump
Adjustment of the pump speed via the speed control of the vacuum pump drive
Ventilation of the unit via the integrated
ventilation valve
, if necessary with inert gas (see
Protection against penetration by fluids by means of an intake separator on the suction
side
Filtering and capturing of residual gases by means of the pressure-side emission conden-
ser
4.3 Set-up
The vacuum controller with the operation and display elements is located at the top of the
device (see section
4.3.1
