HPT™
Power-Limiting Cables
High performance HPT power-limiting heating cables are
designed specifi cally 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 (patent pending)
provides the power-limiting feature of HPT. This PTC (Positive
Temperature Coeffi cient) 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 fi bre substrate, plus an additional fi bre cushion
layer, provides an exceptionally durable high performance
heating cable.
Operating Voltage: 120 / 240 VAC
Maximum Maintenance Temperature: 149°C
