Trace Heating

Chromalox HWM hot water maintenance trace heating cables is a hot water temperature maintenance system that uses self-regulating heat trace technology and provides commercial buildings with immediate hot water.

Chromalox HWM Hot Water Maintenance Trace Heating Cable  – Features

  • Energy efficient HWM self regulating cables requires less energy as less heat is required
  • Simple to install cable and can be cut to any length (see max circuit length)
  • Field splices can be performed easily in minutes with no scrap or wasted cold sections
  • Can be single overlapped without burnout, which simplifies heat tracing of in-line process equipment such as valves, elbows and pumps
  • Chromalox termination, splice, tee and end seal kits reduce installation time


Chromalox HWM heat trace cable is available in – 5 and 10 watts per foot.

  • Approximate Cable Size : 3/8″W x 1/8″H
  • Available Models (Voltages) : 120 and 208-277V
  • Minimum Cable Bend Radius : 1-1/8″
  • Trace Heating Cable Circuit Lengths : Up to 800 feet
  • Minimum Install Temperature : -40°F (-40°C)

A Twin 16 AWG Copper Buss Wires are able to Provide reliable electrical current capability.

B Semiconductive Polymer Core Matrix is the ‘self regulating component of the cable and it’s electrical resistance varies with temperature.

C Flame Retardant and electrically insulates the matric and buss wires and provides resistance to water and some inorganic chemical solutions.

D Metallic Grounding Braid that provides additional mechanical protection in any environment, and a positive ground path.

E Fluoropolymer Outer Jacket is a corrosion resistant, flame retardant overjacket is highly effective in many environments.
