Product Specifications
Application . . .
Freeze Protection 5°C. Suitable for steam service to 595°C.
TubeTrace HTX is a pre-engineered electric traced tube
bundle for steam sample lines and impulse lines to pressure
transmitters. TubeTrace HTX will provide water freeze protection during -40°C 10 m/s wind conditions. HTX is suitable for superheat steam service temperatures up to 595°C.
In the past, bundles subject to high temperature exposure
were heat traced with series resistance mineral insulated
(MI) heater cables that were custom made to length to fit
each application. Measurement errors rendered bundles
with MI heater cable unusable. TubeTrace HTX solves this
problem with Thermon parallel resistance HPT heater cable.
Bundles may be purchased in long rolls and “cut-to-length”
into smaller sections in the field for any application. This
minimizes waste and speeds up installation and engineering
time. HPT is contained within TubeTrace with a “double layer
thermal insulation system” that isolates it from extreme heat
exposure. TubeTrace HTX bundles can be controlled with
ambient sensing systems that turn heater cables on when
outdoor conditions approach freezing.
TubeTrace HTX bundles are designed to withstand 595°C
superheat steam service even when power is applied to the
heater cable during ambient conditions of 5°C, no wind.

Power Output Curves . . .
Circuit Breaker Sizing and Type . . .
The power outputs shown apply to cable installed on insulated metallic pipe (using the procedures outlined in IEEE
Standard 515-1997) at the service voltages stated below.
Power output will increase due to the thermal efficiency of
TubeTrace.
Maximum circuit lengths for various circuit breaker
amperages are shown below. Circuit breaker sizing and
earth-fault protection should be based on applicable local
codes. For information on design and performance on
other voltages, contact Thermon.
