Freeze protection 5°C for steam lines. Continuous

exposure to 593°C .TubeTrace HTX2 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 -30°C with 25 mph 40 kph

wind conditions. 

HTX2 is suitable for superheat steam service

temperatures up to 1100°F (593°C) for a duration of 2

minutes per cycle.

 

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 HTX2 solves this

with Thermon parallel resistance HPT heat trace isolated

from direct contact with high temperature tubing.
