CWM features aparallel heating core that produces uniformthermal output over its entire length. Using asingle power point, you can easily confi gureand install a heat tracing system as short asseveral feet or as long as 780 feet right in thefi eld. System design only requires that youmatch the CWM cable thermal output to theheat loss of your piping system.CWM is fl exible at most ambient temperaturesand can be wrapped around pipingand complex fi ttings. It is rugged, easy tomonitor and maintain temperature, and haszero inrush at start-up. With 392°F (200°C)fl uoropolymer electrical insulation overjacketing,CWM has outstanding electricaland thermal properties, and is well suited formost chemically hostile environments. Anextensive range of wattages and voltages areavailable immediately from Chromalox stock.FeaturesG• Durable, non-aging fluoropolymer jacketensures long service life and can be used insome hostile environments.• Flexible, easy to install on most equipmentand delivers long-term reliable performance.• Eliminates the need for oversized wiring orswitchgear.• Accurate temperature, reliable electric heatthat can be consistently controlled and easilymonitored.• Safe and rugged.• Parallel circuitry allows cut-to-length.• High performance, rated to withstand upto 392°F saturated steam (190 psig) temperature(power off).• Low profile, uses standard size thermalinsulation on piping and processequipment.FOutputTemperatureConstant WattageOutputNote — Consult maximum maintenance temperature chart on page G-15for allowable watt densities.EDConstructionABCDEFGCTwin 12 AWG Copper Buss Wires —Provide reliable, consistent electricalcurrent.FEP Insulation Jacket — Electricallyinsulates buss wires.Pairing Jacket — Secures two buss wirestogether and provides wrapping surfacefor Nichrome wire.Nickel Chromium Wire — Heatingcomponent of the cable.FEP Insulation — Rugged outer sheathprotects heating cable, assures longerservice life, and provides protectionagainst environmental application hazards.Tinned Copper Braid — Plated copperbraid increases robust construction,provides ground path and providesadditional protection in any location.Suffi x “C” in model number.FEP Overjacket (optional) —Fluoropolymer overjacket, over the braid,provides protection from most aqueousand chemically corrosive solutions.
