6.2 Conveying Condensable Vapours
The machine, equipped either with a gas ballast valve or a dilution gas system, is suitable
for the conveyance of condensable vapours within the gas flow.
If condensable vapours are to be conveyed:
START
Open the gas ballast
valve* or the
dilution gas sytem*
(solenoid valve)
Warm up the
machine
30 minutes
30 minutes
• Open the inlet
valve
• Perform the process
• Close the inlet
valve
Close the gas ballast
valve*
or
the dilution gas
system*
END
* optional accessories
• Continuously drain condensate from the condensate drain plug (CD) of the silencer
(SI) (Optional).
6.3 Liquid Flushing Procedure
If after the application process a liquid flushing is required:
START
Reduce the motor
speed to 10 Hz* with
the inlet valve closed
Open the liquid
flushing device
(solenoid valve)
The flushing duration
depends on the application
Adapt the flushing
liquid flow acc. to the
application
requirements
Close the liquid
flushing device
END
* minimum admissible frequency
NOTE:
With gas lubricated double mechanical seals, the minimum admissible frequency
is 25 Hz.
6.4 Gas Purging Procedure
The machine can optionally be equipped with a purge gas system.
If after the application process a gas purge is required, i.e. after a liquid flushing se-
quence or to render the compression chamber inert:
START
Close the inlet valve
Open the purge gas
(solenoid valve)
The flushing duration
depends on the application
Close the purge gas
END
min. 200 seconds to render
the machine inert
