Cellex TubeTrace HTX ® ® Tubing Bundles HPT Power-Limiting Heating Cable TM Product Specifications Application . . . Freeze Protection 5°C. Suitable for steam service to 595°C. TubeTrace HTX is a pre-engineered electric traced tube bundle for steam sample lines and impulse lines to pressure transmitters. TubeTrace HTX will provide water freeze protection during -40°C 10 m/s wind conditions. HTX is suitable for superheat steam service temperatures up to 595°C. 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 HTX 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 HTX bundles can be controlled with ambient sensing systems that turn heater cables on when outdoor conditions approach freezing. TubeTrace HTX bundles are designed to withstand 595°C superheat steam service even when power is applied to the heater cable during ambient conditions of 5°C, no wind. Ratings/Specifications . . .
