Preparation for commissioning
The customer must provide the RWO Oil Separator
System SKIT S-DEB with the following media.
6.1
Compressed air
WARNING
Lines under pressure bear a risk of injury.
Before taking up the work, check compressed air
lines and make sure that they are not under pressure.
Attention!
The compressed air supply to the system must be done
through the service air system for unimportant consumers.
The compressed air supply is made via a cutting-ring
screw connection (pos. 6). This is to be finished on site
with a tube
Æ
8x1 mm and an air pressure of approx. 6-8
bar. We recommend to provide the compressed air line
with a filter and maintenance unit.
6.2
Flushing water
WARNING
Lines under pressure bear a risk of injury.
Before taking up the work, check water lines and
make sure that they are not under pressure.
The standard system requires clean water with a pressure
of between 1 and max. 1.5 bar at the flushing water inlet
valve (pos. 15) for the oil discharge and the backflush of
the coalescer. For the 15ppm (5ppm) alarm device
(pos. 17), another flush connection (pipe
Æ
8x1 mm) is
provided. Both sea water and desalted water are suitable
for this purpose. The amount of consumption is low, it
mainly depends on the oil amount to be separated and on
the flushing water pressure. As a rough guide value,
estimate approx. 10% of the oil separator for systems up
to 0.25 m³ and
approx. 5% for systems with 0.5 m³ and more per
discharge process.
