Freeze protection 5°C for steam lines. Continuous

exposure to 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 -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 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 593°C steam exposure temperature

even when power is applied to the heat trace during

ambient conditions of 5°C.
