PowerHeat (PHT)

PowerHeat (PHT) is a high power, high temperature constant wattage heating cable that can be used for freeze protection and temperature maintainance of pipework and vessels. if has a maximum withstand temperature of 285°C (545°F).

PowerHeat (PHT) can be cut-to-length on site to match exact piping lengths without any complicated design considerations. PowerHeat (PHT) can be used to replace MI cables. Series resistance Mi circuits must be specifically designed for a particular pipe length and cannot be modified to suit site changes.

PowerHeat (PHT) is approved for use in non-hazardous, and hazardous areas to worldwide standard.

Example of Applications

  • Process temperature maintenance of pipework and vessels
  • Suitable for use in safe, hazardous and corrosive areas
  • Can be used to replace MI cables

Benefits

  • High resistance to chemical attack
  • Available for 110V and 240VAC
  • Power outputs up to 70W/m

The installation of PowerHeat (PHT) is quick and simple and requires no special skills or tools. Termination, splicing and power connection components are all provided in convenient kits.

  • Product Specification - maximum withstand temperature 285°C (545°F)
    PowerHeat (PHT) is available in 30, 50 and 70 W/m outputs as illustrated on the graph to the right. The graph shows the nominal power output at 230V when installed on insulated metal pipes.
