Constructedof a semiconductive heater matrix extrudedbetween parallel buss wires, a self- regulatingcable adjusts its output to independentlyrespond to temperatures all along its length. Astemperatures increase, the heater’s resistanceincreases which lowers the output wattage.Conversely, as the temperature decreases, theresistance decreases and the cable producesmore heat. The result — an energy effi cientheating cable.Self-regulating cables are fl exible, can becut-to-length in the fi eld and can be singleoverlapped without fear of burnout in areaswhere complex piping and equipment requireadditional heat trace cable.Chromalox manufactures low (SRL) andmedium (SRM/E) temperature self-regulatingheating cable for use on 120 and 208 to 277V.Equipped with a ground braid and optional TPRor FEP jacket, Chromalox self-regulating cablesare third party tested and approved for use inharsh corrosive and hazardous applications.Constant WattageChromalox CWM Constant Wattage HeatingCables are ideally suited for applications wherea particular watt density is required at all times.The heater element consists of a nichrome wirewrapped around parallel, insulated buss wires.At specifi c intervals, a short section of insulationis removed from alternating buss wires tocreate connection nodes for the nichrome wire.The result is a network of parallel resistorsalong the entire length of constant wattagecable.Constant wattage cables are fl exible, can becut-to-length in the fi eld, and are manufacturedfor use on voltages from 120 to 480V. Althoughnot suited for overlapping, its constant outputmakes it an ideal choice for higher temperatureapplications where higher watt densities arerequired. Equipped with a ground braid and optionalFEP jacket, Chromalox constant wattagecables are third party tested and approved foruse in harsh, corrosive and hazardous areas.Contact your Local Chromalox Sales offi ce forhazardous area designs.Mineral InsulatedChromalox MI Mineral Insulated Heating Cablesare the most rugged heating cable in Chromalox'sproduct line. Constructed of a solid seriesresistor element embedded in highly compactedmineral insulation, MI cables are built tohandle high temperature, high wattage applications.The series resistor and mineral insulationare encased in a metallic jacket of Alloy 825 forhigh temperature or corrosive applications.Mineral insulated cables are factory assembledand tested, ensuring the highest quality product.Since the units consist of a series resistor,virtually any wattage/voltage/length cable configurationcan be produced within the cable'sphysical operating limits. Chromalox mineralinsulated cables are available for use up to600V and are tested and approved for use incorrosive and hazardous areas. Optional accessoriesinclude pulling eyes and reverse glands.Other special features are also available.Commercial Cable ApplicationsSelf-Regulating Freeze ProtectionChromalox SRF Self Regulating Freeze ProtectionHeating Cable is a self-regulating cabledesigned for the freeze protection of waterlines. The self-regulating matrix allows foroverlapping and easy fi eld installation. SRF alsolowers its output and energy consumption asthe temperature increases thus lowering energycosts. The 16 AWG buss wires provide for longcircuits which reduce the number of accessoriesrequired.A braided and braided with overjacket constructionis available. Braided cable should be usedon dry pipes and dry locations. The overjacketconstruction is suitable for wet locations whereoccasional exposure to moisture is expected.SRF heating cable is not for use in hazardouslocations. Consult the Industrial Cable Productsin this section for cables suitable for hazardouslocations.Self-Regulating Roof & GutterDe-IcingSRF-RG Heating Cable is specifi cally designedfor roof and gutter de-icing applications.SRF-RG features a self-regulating matrix thatreduces output as snow melt requirementsdecrease or when warm weather is present.The braided and overjacketed constructionprovides reliable moisture protection. The 16AWG buss wires allow ample circuit lengthsand rugged design. Accessories are availablefor mounting to roofs and gutters.194
