Applications
Trace heating compensates for the heat loss through the insulation to
maintain the pipe and fluid at temperatures above the freezing or solidifi-
cation point. Thus, trace heating is critical for pipe freeze protection sys-
tems that are expected to have stagnant fluids for prolonged durations.
Freeze protection:
Water, and fluids containing significant water, expand as they freeze.
This expansion can cause the pipe to be blocked or break leading to:
Economic losses: A frozen water pipe leading to a critical process
like a frozen pipe in a waste water treatment plant or cooling tower
can shut down the operation causing high economic losses.
Safety issues: A frozen pipe to safety showers can jeopardize per-
sonnel safety in the event of hazardous chemical exposure.
Temperature maintenance:
A process temperature maintenance system can maintain the temper-
ature of the fluid in a pipe to the desired level over a broad range of
temperatures.
Maintaining liquids within the specified temperature range allows you
to cost-effectively transport the fluids from one location to another, op-
erate your processes at maximum efficiencies, and safely start/shut
down your operations.

Follow these guidelines to avoid personal injury or material damage.
WARNING
Risk of fire or electrical shock due to electric trace heating system.
Risk of bursting of the cable gland.
At temperatures below -40°C, make sure that no mechanical shock
of x>4 joule is applied to the cable gland type Wiska ESKE/1 25 LT.
Protect the cable gland from mechanical shock.
CAUTION
Danger of burning due to electric heating system
Danger of burning from hot surface
Disconnect the heating circuit from the power supply before removing
the pipe insulation. Allow the heating system to cool down.
Disconnect the heating circuit from the power supply before working
on the enclosure. Allow the enclosure to cool down.

After opening the enclosure, check that the enclosure sealing is in
good condition. Ensure that the enclosure sealing is elastic and free
of cracks. If the enclosure sealing is damaged, contact
BARTEC GmbH.
CAUTION
The trace heating system is only applicable in case of workpiece tem-
perature is higher than the layout ambient temperature.
For safe installation and operation of BARTEC Self-regulating trace
heating systems the technical requirements and instructions given in
this Design Guide, all applicable documents and the corresponding
manuals of the installed products or products to be use must be fol-
lowed. Keep these instructions for future reference. If applicable,
leave them with the end user. Retain the trace heating system docu-
mentation for each trace heating circuit as long as the system is in
use.
All electrical systems and installations must comply with BARTEC
GmbH requirements and be installed in accordance with the relevant
electrical codes and any other applicable national and local codes.
Use BARTEC Self-regulating trace heating cables in accordance with
the intended use and strictly comply with the operational data speci-
fied in section Technical Data. Install all components of the trace heat-
ing system carefully.
Any defective component of the trace heating system must be re-
placed before installation. Replace each defect component of the
trace heating system.
Use only original BARTEC accessories and spare parts.
Note that the Applicable Documents listed below shows further im-
portant information and must be observed in addition to this manual.
