TubeTrace HTX2
Tubing Bundles

TubeTrace HTX2 is a pre-engineered electric traced tube bundle for steam sample lines and impulse lines to pressure transmitters. TubeTrace HTX2 will provide water freeze protection during -34°C 10 m/s wind conditions. HTX2 is suitable for superheat steam service temperatures up to 595°C for a duration of 2 minutes per cycle.

In the past, bundles subject to high temperature exposure were heat traced with series resistance mineral insulated (MI) heater cables that were custom made to length to fit each application. Measurement errors rendered bundles with MI heater cable unusable. TubeTrace HTX2 solves this problem with Thermon parallel resistance HPT heater cable. Bundles may be purchased in long rolls and “cut-to-length” into smaller sections in the field for any application. This minimizes waste and speeds up installation and engineering time. HPT is contained within TubeTrace with a “double layer thermal insulation system” that isolates it from extreme heat exposure. TubeTrace HTX2 bundles can be controlled with ambient sensing systems that turn heater cables on when outdoor conditions approach freezing.

TubeTrace HTX2 bundles are suitable for intermittent superheat steam service temperatures to 595°C even when power is applied to the heater cable during ambient conditions of 5°C, no wind.
