TubeTrace Type ME Electrically Heated Instrument Tubing with HPT Power-Limiting Heat Tracing, 3 Tubes, 3/8″ / 1/4″ / 1/8″ Process Tubes O.D., PFA Teflon Process Tube Material, HPT 20 w/ft. 120 Vac Heat Trace Type, OJ/Fluoropolymer Heat Trace Option, ATP Bundle Jacket, 0.047″ (Plastic Only) / 0.040″ (Plastic Only) / 0.030″ Process Tubes Wall Thickness TubeTrace, with “cut-to-length” HPT power-limiting heat tracing, is designed to provide freeze protection or temperature maintenance from 40°F (5°C) to 350°F (177°C) for tubing where high temperature exposure capability is possible. HPT withstands temperature exposures of 500°F (260°C). The composite construction of the heating element and fiber substrate, plus an additional fiber cushion layer, make HPT an exceptionally durable heating cable. Durability has made TubeTrace with HPT the industry standard for high temperature emissions and process analyzer applications. Power-Limiting HPT heat tracing: • Varies in response to the surrounding conditions along the entire length of a circuit. • Lower risk of overheating the tube or product than with constant watt designs. • HPT is approved for use in ordinary (non-classified) areas and hazardous (classified) areas.

Teflon is a trademark of E.I. du Pont de Nemours & Co., Inc. 2. Black ATP is standard, other jacket materials are available. 3. CL. II, Div. 2 requires Thermon design review. This reflects maximum exposure for heater. If bundle jacket is to remain below 140°F (60°C) in +80°F (27°C) ambient (in consideration of personnel burn risk) tube temperature must remain below 400°F (205°C). Alternative designs to keep jacket below 140°F (60°C) in higher ambients and/or with higher tube temperatures are available.
