Constructed of industrialgrade 14 AWG buss wire with a tinned copperbraid and fl uoropolymer overjacket, HSRMensures operating integrity in Div. 1 hazardousenvironments. HSRM heating cable hasa maximum maintenance temperature ratingof 302°F (150°C) and a maximum exposuretemperature of 420˚F (215˚C).Note: Due to the nature of Division 1 hazardouslocation applications consultation with afactory representative is required.Features• Energy effi cient, self-regulating HSRM usesless energy when less heat is required.• Easy to install, HSRM can be cut to anylength (up to max circuit length) in the fi eld.• HSRM features lower installed cost thansteam tracing, less maintenance expenseand less down time.• HSRM can be overlapped without burnout,which simplifi es heat tracing of in-line processequipment such as valves, elbows andpumps.• Chromalox HL Connection Kits reduce installationtime.ConstructionA Twin 14 AWG Copper Buss Wires—Provide reliable electric current capability.B Semiconductive Polymer Core Matrix—“Self-Regulating” component of thecable its electrical resistance varies withtemperature. As process temperaturedrops, the core’s heat output increases; asprocess temperature rises, the heat outputdecreases.C Fluoropolymer Jacket— Flame retardantelectrically insulates the matrix and providescorrosion resistance.D Tinned Copper Braid— Provides additionalmechanical protection in anyenvironment and a positive ground path.E High Temperature FluoropolymerOverjacket— Corrosion resistant, fl ameretardant overjacket is highly effective inmany environments. Protects againstexposure to organic or corrosive solutions.The overjacket also protects against abrasionand impact damage.ApprovalsFM Approved• Class I, Division 1, Groups B, C, D• Class II, Division 1, Groups E, F, G• Class III, Division 1• 5 and 8 Watt rated T3C Temperature Class• 10 Watt rated T3A Temperature Class• 15 and 20 Watt rated T2C Temperature ClassCSA Approved• Class I, Division 1, Groups B, C, D• Class II, Division 1, Groups E, F, G• 5 and 8 Watt rated T3C Temperature Class• 10 Watt rated T3A Temperature Class• 15 and 20 Watt rated T2C Temperature Class102
