Chromalox HWM Hot-water Maintenance Heat Trace Cable

Features

  • Energy-efficient, self-regulating HWM uses less energy when less heat is required.
  • Easy to install, HWM can be cut to any length (up to max. circuit length) in the field.
  • Field splices can be performed easily in minutes with no scrap or wasted cold sections.
  • HWM can be overlapped without burnout, which simplifies heat tracing of in-line equipment such as valves.
  • Because HWM is self-regulating, over-temperature conditions are minimized.
  • Chromalox termination, splice, tee and end seal kits reduce installation time.

The HWM hot water temperature maintenance system utilizes self-regulating heat trace technology. The system, consisting of the self-regulating cable, connection kits, and specialized electronic controls, provides commercial buildings with immediate hot water availability without expensive recirculation systems. It provides a simple, yet energy-efficient approach by providing heat at the point where heat loss occurs. Due to the parallel construction of the self-regulating cable, it can be cut to any length, spliced, tee-branched, and terminated on site. With this product, energy savings may be derived from multiple sources, such as lower supply line heat loss, eliminated return line heat loss, no pump operating costs, and no supply water overheating costs.

Construction

Construction

A. Twin 16 AWG Copper Buss Wires – Provide reliable electric current capability.

B. Semiconductive Polymer Core Matrix – “Self-Regulating” component of the cable its electrical resistance varies with temperature. As process temperature drops,the core’s heat output increases; as process temperature rises, the heat output decreases.

C. Flame Retardant – Electrically insulates the matrix and provides corrosion resistance.

D. Metallic Grounding Braid – Provides additional mechanical protection and a positive ground path.

E. Fluoropolymer Outer Jacket – Corrosion-resistant, flame retardant overjacket is highly effective in many environments. Protects against exposure to organic or corrosive solutions. The overjacket also protects against abrasion and impact damage.

WARNING — A ground fault protection device is required by NEC to minimize the danger of fire if the heating cable is damaged or improperly installed. A minimum trip level of 30mA is recommended to minimize nuisance tripping.
