Self-Regulating Heating Cable
The ElectroMelt EM2-XR heating cable is embedded in concrete pavement to
melt snow and ice that might otherwise accumulate on the surface. The heating
cable responds to the local concrete temperature, increasing output when
concrete temperature drops and decreasing heat output when concrete temper-
ature rises. The self-regulating heating cable cannot overheat and destroy itself,
even if overlapped in the concrete, and therefore does not require the use of
overlimit thermostats. For more detailed information on this cable, see page 25.
