TubeTrace Type SE Electrically Heated Instrument Tubing with HTSX Self-Regulating Heat Tracing, 1/4″ Process Tube O.D., 316 SS Seamless Process Tube Material, HTSX 9 w/ft. 120 Vac Heat Trace Type, ATP Bundle Jacket, 0.035″ Process Tube Wall Thickness TubeTrace, with “cut-to-length” HTSX self-regulating heat tracing, is designed to provide freeze protection or temperature maintenance from 40°F (5°C) to 302°F (150°C) for tubing where high temperature exposure capability is possible. HTSX withstands temperature exposures of 482°F (250°C). Self-regulating HTSX heat tracing: • Varies in response to the surrounding conditions along the entire length of a circuit. • Lower risk of overheating the tube or product. • Installed cost is lower because “cut-to-length” HTSX makes end connections easy with minimal waste. • HTSX is approved for use in ordinary (non-classified) areas and hazardous (classified) areas. Certifications/Approvals: • FM Approval • Ordinary Locations • Hazardous (Classified) Locations o Class I, Division 2, Groups B, C and D o Class II, Division 2, Groups F and G o Class III, Divisions 1 and 2 o Class I, Zones 1 and 2, AEx e II • Canadian Standards Association • Ordinary Locations • Hazardous (Classified) Locations o Class I, Divisions 1 and 2, Groups A, B, C and D o Class II, Divisions 1 and 2, Groups E, F and G o Ex eb IIC o Ex tb IIIC Note: 1. Black ATP is standard, other jacket materials are available. 2. 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.
