Electric heat tracing is a process used to maintain or raise the temperature of pipes, tanks, and vessels in industrial and commercial facilities. It is often used to prevent the formation of frost or ice, to maintain the temperature of viscous materials, or to keep materials at a certain temperature for processing or storage.
There are several types of electric heat tracing systems, including self-regulating, power limiting, and constant wattage. Self-regulating systems adjust the amount of heat they produce based on the temperature of the pipe or vessel, while power limiting systems have a fixed heat output. Constant wattage systems have a fixed heat output that is not influenced by the temperature of the pipe or vessel.
Heat tracing is necessary in industrial and commercial facilities for a number of reasons. In cold climates, it is used to prevent pipes from freezing, which can lead to costly repairs and downtime. In processing and storage facilities, it is used to maintain the temperature of viscous materials, such as oil, to keep them flowing smoothly. It is also used to keep materials at a certain temperature for processing, such as in the food and pharmaceutical industries.
Heat tracing systems can be designed and installed by specialized contractors and are typically controlled by thermostats and other temperature-sensing devices. They can be powered by electricity, steam, or hot water, and are usually equipped with alarms and other safety features to prevent overheating or other hazards.
