Power Limiting Heating Cable HPT THERMON

Self-Regulating Heating Cable   HPT

Self-Regulating Heating Cable   HPT



High performance HPT power-limiting heating cables
are designed specifically for process temperature
maintenance or freeze protection where high maintain
temperatures or high temperature exposure is required.
HPT withstands the temperature exposures associated
with steam purging.
A coiled resistor alloy heating element provides the

powerlimiting feature of HPT. This PTC (Positive Temperature
Coefficient) characteristic decreases the cable’s power
output as the heat-traced product temperature increases
and allows the cable to be overlapped during installation.
The composite construction of the heating element and
fibre substrate, plus an additional fibre cushion layer,
provides an exceptionally durable high performance
heating cable.
HPT cables are certified for use in ordinary (nonclassified)
areas and in potentially explosive atmospheres in
accordance with the ATEX Directive and the IECEx

Thermon offers system accessories designed specifically
for rapid, trouble-free installation of Thermon heating
All HPT cables require a connection kits to comply with
approval requirements. Information on accessories
to complete a heater circuit installation can be found
in the “Heating Cable Systems Accessories” product
specification sheet (Form TEP0010U).
