4.4 The Process Chamber
Operating Instructions
Version 1.5
4.4.16 Active cooling module (option)
4.4.17 Internal Temperature Monitoring (option)
Fig. 4-42 Active cooling module
An active cooling module can also
be fitted at the outlet of the system
to enable additional cooling of sub-
assemblies.
Fig. 4-43 Internal Temperature Sensor
Temperature is monitored in the in-
dividual heat zones by means of
sensors which are located directly at
the conveyor level. A sensor for
measurement of the interior temper-
ature is connected at each nozzle
field.
Tolerances and limit values which
are intended to trigger an alarm can
be selected as desired by the user.

4.5 Pyrolysis System
Operating Instructions
Version 1.5
4.5 Pyrolysis System
Process gas which is contaminated during soldering is purified in the pyrol-
ysis unit and returned to the soldering process.
Fig. 4-45 Gas Flow in the Pyrolysis System
Contaminated gas is exhausted from preheating right on up to the peak
zone. The gas is then purified by means of pyrolysis and is blown back into
the peak zone.
Fig. 4-46 Pyrolysis System
A)Pyrolysis box
B)Venturi tube
The Venturi tube propels gas
through the pyrolysis system.
Throughput is measured by means
of the flow meter. The flow meter is
located on the adjusting panel for
nitrogen distribution (see Fig. 4-54).
Fig. 4-47 Pyrolysis Connections
• 3 heater connections
• 1 pc. connection for gas tempera-
ture Pyrolysis.
• 3 pc. temperature sensors
