What is Trace Heating (Heat Tracing)?
Electric Surface/Trace Heating (Heat Tracing) is the application of a compensating heat source to a pipe, surface or vessel, to maintain a specified temperature. 2. How does Heat Tracing work? Electric Trace/Surface Heating replaces the losses of heat from a surface, to allow temperature maintenance of the product, which Thermal Insulation alone can not maintain. 3. What is Constant Wattage cable? Constant wattage heaters exist in various forms, of which the more recent zonal parallel circuit devices are the most convenient, since these may be ‘cut to length’, within practical limits, on site. The output of constant wattage tape is virtually constant along the tape length, due to the consistent nature of the wire element.
