Installation
Information on Electrically Operated
Trace Heating Systems In
the following text, we would like to give
you some useful information on the
installation of electrical trace heating
systems:
A) Temperature regulator
and terminal box
The temperature regulator
and the terminal box are installed at
their designated location first. The
attachment of the temperature sensors is
dependent on the type of installation of
the heater bands.
In case of a parallel
installation of the heater band,
aluminium adhesive tape is used to fasten
the sensor on the pipeline at some
distance from the heater band.
If the heater bands have
been wrapped around the product pipe in
the form of a spiral, it is important to
make sure that the sensor is not covered
by a heater band. ( Exception in the case
of plastic pipes: Here the temperature
sensor must be fitted underneath the
heating cable.)
Note: It is important to
ensure that each thermostat is equipped
with an appropriate fuse.
B) Installation of
heating cables and heater bands
Generally, it must be
ensured that the heating cables and
heater bands do not cross over or lie on
top one another.
In the case of parallel
installation, the heating cables
should be fastened at least every 300 mm
with aluminium adhesive tape.
If several parallel running
heat conductors are being used, these
conductors must then be installed at a
sufficient distance from one another:
In the case of spiral-shaped
installation, the heating cables
should be fastened at least every 1000 mm
with aluminium adhesive tape:
The gradient must remain
constant over the entire length of the
pipe.
C) Installation in case
of available steam heating
If and when requested,
electrical heating cables can also be
installed for steam heating systems
In these cases, the heating
cables are never allowed to be installed
in spiral form in order to avoid coming
into contact with the steam heating
system. Instead, a single or double
parallel installation is recommended.
D) Further information
Following the installation
of the thermal insulation, the continuity
and insulation resistance of the heating
cables must be checked again and the
indentification stickers then be attached
accordingliy.
In addition to these
instructions, any other applicable
regulations must be strictly observed.
