AThermTrac system provides a cost-effective alternative
to conventional resistance heat tracing on long pipelines
by eliminating the need for an extensive power distribution
system. A pipeline up to 25 kilometers long can be traced
from a single power point. The versatility of the system
makes it ideal for temperature maintenance, freeze
protection and heat-up applications.
The system generates heat in the heat tube by the
return electrical current flowing through the impedance
of the inner skin of the heat tube. There is no voltage or
current on the outer skin of the heat tube.
The ThermTrac insulated conductor is the heart of
Thermon’s skin effect heating system. This conductor is
custom designed by Thermon with dielectric insulation
and scuff jacket to meet specfic project applications.
For freeze protection and low temperature maintenance
applications, polyolefin-insulated copper conductors may
be utilized. Fluoropolymer-insulated conductors provide
superior temperature, flexibility and durability properties
necessary for higher temperature applications.
