A motor drives the spindles, which
in turn lift the process chamber.
Positioning of the process cham-
bers is initialized by buttons on the
main screen.

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).

• 3 heater connections
• 1 pc. connection for gas tempera-
ture Pyrolysis.
• 3 pc. temperature sensors

4.6 Condensate Trap
Operating Instructions
Version 1.5
4.6 Condensate Trap
4.6.1 Condensate trap VXP+
The condensate trap (VXP+) is located on the back of the system under-
neath the cooling tract.
Fig. 4-48 Condensate Trap VXP+
Contaminated process gas is exhausted after the last peak zone and fed to
the condensate trap where it’s cooled down and purified. At the end of the
process it’s returned to the cooling tract.
