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

TubeTrace with HT heating cables Thermon

APPLICATION TubeTrace with HT
Freeze protection 40°F (5°C) of steam lines. Continuous
exposure to 750°F (399°C).TubeTrace HT is a preengineered electric traced tube bundle for steam sample
lines and impulse lines to pressure transmitters. TubeTrace
HT will provide water freeze protection in ambient
conditions down to -50°F (-45°C) with 25 mph (40 kph)
wind conditions.
In the past, 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 HT solves this
with Thermon parallel resistance HPT heat trace isolated
from direct contact with high temperature tubing.
TubeTrace HT bundles are designed to withstand
continuous 750°F (399°C) steam exposure temperature
even when power is applied to the heat trace during
ambient conditions of 40°F (5°C).

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.
