PowerHeat (AHT)

PowerHeat (AHT) is a unique patented, high power, high temperature, high mechanical strength constant wattage heating cable that can be used for freeze protection and temperature maintenance of pipework and vessels. It has a maximum temperature of 500°C (932°F) which makes it the highest temperature rated cut-to-length heating cable in the world!

PowerHeat (AHT) has an aluminium outer jacket giving it the highest mechanical strength of any cut-to-length heating cable in the world!

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

The aluminium jacket allows the cable to be formed around valves, pumps and instruments.

Example of Applications

  • Freeze protection of pipes and vessels
  • Temperature maintenance of processes in pipes and vessels

Benefits

  • Aluminum jacket for high mechanical strength
  • Available for 110V and 240VAC
  • Power outputs up to 150W/m

PowerHeat (AHT) can be cut-to-length at site to match exact piping lengths without any complicated design considerations.

PowerHeat (AHT) can, in most cases, replace MI cables. Series resistance MI circuits must be specifically designed for a particular pipe length and cannot be modified to suit site changes.

  • Product Specification - maximum withstand temperature 500°C (932°F)
    PowerHeat (AHT) is available in 15, 30, 50, 70, 100 and 150 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.
