SEI/MEI-HTX

Electrically Heated Tubing Bundles Thermon SEI/MEI-HTX

Application:

Freeze protection 40°F (5°C) of steam lines. Continuous exposure to 1100°F (593°C). TubeTrace HTX is a pre-engineered electric traced tube bundle for steam sample lines and impulse lines to pressure transmitters. TubeTraceHTX will provide water freeze protection in ambientconditions 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 oftenrequired. TubeTrace HTX solves this with Thermon parallelresistance HPT heat trace isolated from direct contact with high temperature tubing.

TubeTrace HTX bundles are designed to withstandcontinuous 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.

Circuit breaker sizing:

Maximum circuit lengths for various circuit breakeramperages 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 ground-fault protection requirements.
