Self-regulating trace heaters consist of two parallel bus wires embedded in a heating matrix doped with carbon particles. When the temperature rises in operation, molecular expansion increases the distance between the carbon particles. The resistance increases and output drops. When temperatures fall, this process is reversed and output increases. This physical property means that the heater will never overheat, can be assembled crosswise and can be operated without a temperature controller. Moreover, selected ELSR heating cables are approved for use in hazardous areas.
The ELSR (eltherm-self-regulating) trace heater is used for frost protection and temperature maintenance on vessels, pipes, valves, etc. It may be immersed in fluids. For use in aggressive environments (e.g. in chemical or petrochemical industry), the trace heater is coated with a special chemically resistant* outer jacket (fluoropolymer), option “BOT”.
We develop complete solutions for processes in production, storage, handling, and transport. Our engineers are committed to understanding your exact technical requirements. Their pride is to develop the best possible heat tracing solution.
