4.1.17. Heating Line
STS tankers have a heating line to heat
the transported material. Heating is
being done in two different ways, with
steam and liquid.
Heating with steam
•
Connect the hose line that will sup-
ply the system with hot steam to the
heating line inlet (1).
•
Connect the hose line to be used to
evacuate the steam in the system to
the heating line outlet (2).
•
Take the ball valve (3) to the closed
position and perform the heating op-
eration by giving hot steam to the
system.
•
The heating line is designed for a
maximum pressure of 7 bar. The
safety valve (4) on the line prevents
the pressure in the system to ex-
ceed 7 bar.
•
In addition, the pressure of the sys-
tem can be observed with the man-
ometer (5) on the heating line.

Heating with liquid
Closed circuit heating system is used for
heating with hot liquid.
The heater and the pump are usually
placed inside the heater cabinet (6) on
the left side of the tanker. The fuel tank
(7), which provides the fuel requirement
of the heater, is located over the cabinet.

Operation
of
the
liquid
heating
system:
•
Liquid heating system works with 24
volt energy. It is energized by the
socket (1) on the front of the tank.
Electrical connection
When making the electrical
connection, the (+) pole and
the
(-)
pole
must
not
be
confused.
•
Never confuse with (+) and (–) poles
during the first connection to the
tractor.
•
The heater automatically stops at
78°C with the thermostat on it during
operation, and restarts automati-
cally at 72°C.
•
Open the ball valve (2) at the inlet of
the heating duct located at the back
of the tank.
