What is Self Limiting/Regulating cable?
Self Regulating heating tape adjusts heat output to equal the heat loss from the pipe work. As pipe temperature falls under no-flow conditions or due to the decreases in external or internal temperature the electrical conductivity of the semi-conductive polymer core increases causing the tape to increase output. As the pipe temperature increases under flow conditions or as a result of increasing external or internal temperature the conductivity reduces and output decreases. 5. Constant Wattage or Self Limiting, which choice to make? F1078 CONSTANT WATTAGE OR SELF LIMITING 6. Do I need to use Thermal Insulation? Thermal Insulation is recommended on all applications. Without Insulation surface heat losses can increase approx 4-5 times. 7. Can I use Surface Heating (ESH) to heat raise pipes and vessels? Electric Surface Heating (ESH) can be used to heat raise pipes and vessels. However, it is usually more economic to maintain heating on a pipeline than to provide a heating system designed
