When selecting and designing a trace heating system, different aspects such as cost, reliability or efficiency are often some of the first criteria to come to mind. But one of the most important aspects of this decision includes choosing which sensing method to rely on. Factors that can influence which sensing method is best for your application include whether or not the system is required to be controlled based on ambient or pipe surface temperature.

Deciding which method of heat tracing is best for your application is a tough decision that involves many factors. Cost, effectiveness, environment and more are all different aspects to consider when making this decision. Typically, the decision comes down to one of two forms of heat tracing: steam or electric. While Steam Tracing has historically been a more common form of heat tracing, advances in modern technology have made electric a desirable route to go as well.
Designing high temperature electric heat tracing systems in hazardous areas can be a difficult challenge, especially when process temperatures approach the area classification limit. This restricts the allowable temperature differential between what is heated and the surface temperature of the heaters.
Electric Heat Tracing is used in many process industries to maintain process fluids at the desired temperatures. A look at five common uses of heat-tracing applications can help users select the most appropriate technology for their application. These are the most commonly encountered needs in the industrial sector.
