When dealing with high temperature applications, selection of the correct cable is critical. Often, the determining factor in cable selection is not the process maintenance temperature, but the potential cable exposure temperature.
For instance, if a process line is steam cleaned, the temperature of the steam will degrade and eventually destroy the power output of a self-regulating cable intended for low exposure temperatures. Also, in high temperature applications, sheath temperature considerations become important due to the potential for auto-ignition of combustible gases in the area. Drexan HeatTracer has the engineering and design capability to deliver the correct heating cable for these applications, whether the product is PipeGuard Hot, PipeGuard CMH, or Mineral Insulated series type cable.
The integrity of a trace heating system depends upon on how accurately the cable is selected and how well it is installed. An improperly designed and installed trace heating system could result in cable failure and possible physical injury.
