Each heating zone consists of an upper convection heating and a bot-
tom radiation heating.
The upper heating areas emit convection heat with the help of hot air
fans to the
heating chamber .
The first preheating zone and the peak zone are equipped with 3000W
heating power. For the preheating zones 2, 3 and 4
[only 551.15]
or 5
and 6
[only 551.19]
are 2000 W Heating capacity adequately dimen-
sioned.
Underneath the bottom cover there are for heating zones with 1000W
heating power each. The radiation heat of the bottom heating zones
takes care for an equal heating of the PCB and a good soldering
result.

The temperatures of all heating areas can be set individu-
ally.
The maximum power consumption of soldering ovens 551.10 / 551.15
is limited by the controller to 11 kW, the power consumption of sol-
dering oven
551.19 at 22 kW to avoid overloading the mains supply
during the heating phase. The available heating capacity is split as
required by an intelligent software control to all heating zones.
The upper part of the heating chamber contains also a
cooling zone
and an exhaust hood for the inlet area as well as for the outlet area.
About the exhaust hoods soldering and glue fumes are sucked and
thus prevents the escape of toxic fumes.
The transport of the PCBs through the heating chamber takes place
by a
mesh belt with 440 mm width (useable working width 405 mm).
The maximum assembly height is 45 mm. The conveyor speed is ad-
justable between 15-90 cm/min and depends on the required solder-
ing profile.
