12.1 Safety regulations for the use
of the heat exchanger
Danger
When operating the compressor, please
observe the general safety regulations
laid forth in the compressor operating
manual.
The heat exchanger operates fully
automatically. Operating errors at the
heat exchanger are excluded.
12.2 Design and operation
System function diagram:
see page 78, fig. 4
* The compressed air is heated up in a
heat exchanger by means of the engine
oil.
* The diesel engine is equipped with an
oil temperature regulator, which ensures
that the engine oil has the proper
minimum temperature required for
operation and which bypasses the heat
exchanger at the diesel engine during
start-up and warm-up until the required
engine oil temperature has been
reached.
The second oil temperature regulator,
which is located in the oil line, for heating
up the compressed air ensures that the
compressed air may not be heated up
exceeding maximum specified
temperatures during summer operation.
This fully automatical uniform
temperature control ensures both the
proper temperature of the compressed air
and the proper engine oil temperature
irrespective of the ambient temperatures
which the installation will be operated in.
12.3 Maintenance/Care
This system is maintenance-free.
For information on engine oil change see
the operating instructions of the engine.
12.4 Troubleshooting
Compressed air temperature too low
Defective oil temperature regulator in
the engine or in the oil line -> replace.
Compressed air temperature too high
Defective oil temperature regulator in
the oil line -> replace.
