TubeTrace with HTX (TubeTrace® Type SEI/MEI – HTX)

TubeTrace with HTX heating cables Thermon

APPLICATION TubeTrace with HTX
Freeze protection 40°F (5°C) of steam lines. Continuous
exposure to 1100°F (593°C). TubeTrace HTX is a preengineered electric traced tube bundle for steam sample
lines and impulse lines to pressure transmitters. TubeTrace
HTX will provide water freeze protection in ambient
conditions down to -50°F (-45°C) with 25 mph (40 kph)
wind conditions.
In the past, the only option for tubing subject to high
temperature exposure was heat traced with series
resistance mineral insulated (MIQ) heat trace. MIQ
heaters are custom made to fit each application, so long
lead times and specific field measurments are often
required. TubeTrace HTX solves this with Thermon parallel
resistance HPT heat trace isolated from direct contact with
high temperature tubing.
TubeTrace HTX bundles are designed to withstand
continuous 1100°F (593°C) superheat steam temperature
even when power is applied to the heat trace during
ambient conditions of 40°F (5°C).

POWER OUTPUT CURVES
The power outputs shown apply to cable installed on
insulated metallic pipe (using the procedures outlined in
IEEE Standard 515) at the service voltages stated below.
For use on other service voltages, contact Thermon.

CIRCUIT BREAKER SIZING
Maximum circuit lengths for various circuit breaker
amperages are shown below. Breaker sizing should be
based on the National Electrical Code, Canadian Electrical
Code or any other applicable code. The National Electrical
Code and Canadian Electrical Code require ground-fault
protection of equipment for each branch circuit supplying
electric heating equipment. Check local codes for groundfault protection requirements.
