nVent RAYCHEM constant wattage parallel circuit trace heating cables (also referred as zone heaters) are used for applications of frost protection of pipes, temperature maintenance of process fluids and tank heating


  • Easy to use: they can be cut-to-length on site
  • Provide high power output at elevated temperatures
  • Offer an economical alternative where benefits of self-regulating trace heating cables are not required
  • Reduces number of circuits, available for voltages up to 400 Vac
