Nelson™ Heat Trace Snow Melting System
Nelson™ Heat Trace™ Snow Melting System
Nelson™ Heat Trace snow melting system is made up of MI (mineral insulated) cable.
It is used for the electric heating of paved surfaces such as sidewalks, driveways and parking ramps is an efficient, economical method of preventing snow and ice accumulation. Heat Trace electrical snow melting systems replace older, less efficient means of snow removal such as heated water or oil circulating systems, plowing or shoveling, and offer an effective alternative to the application of salts and other chemicals which result in pavement damage and environmental pollution.

Features

  • Mineral insulated cable is a high performance, industrial quality, series resistance heating cable which uses a high temperature metallic conductor as the heating element. The conductor is insulated with an inorganic dielectric, Magnesium Oxide (Mg0). Th
  • Constant wattage: MI cable provides a series resistance heating system so that the power output is uniform over the entire length of the cable. Parallel, self-regulating heaters develop significant voltage drop over their circuit length which results in
  • No inrush: MI cable eliminates oversizing of circuit breakers because of cold temperature inrush. Most MI cable does not exhibit cold temperature inrush, and circuit breakers are sized for steady state load. Circuit breakers for parallel, self-regulating
  • Rugged sheath: MI cables have a rugged, Alloy 825 outer sheath which resists mechanical damage during installation. Parallel, self-regulating heaters have plastic sheaths which are easily damaged during installation
  • High voltage: MI cables can be operated up to 600 volts while parallel, self-regulating heaters are limited to 277 volts. Increased voltage results in longer circuit lengths and fewer circuits. In addition, increased voltage correspondingly reduces amper
  • High power: MI cable can be operated up to 70 watts per foot. Because of the superior performance capabilities of MI cable, power outputs can be increased, which reduces the amount of cable necessary for the required watt density. Parallel, self-regulati
  • High temperature exposure: MI cables can withstand high temperatures, a requirement for installation in asphalt. Parallel, self-regulating heaters are damaged by these temperatures
  • Conduit installation: MI cables can be installed inside conduit without deration of the heater. No additional cable is required if the cable is installed in conduit. Parallel, self-regulating heater power output must be de-rated as much as 40% if install
  • Design options: MI cables are available in a wide variety of resistances and with either one or two conductors. More design choices allow the designer to provide the most economical heating solution, taking many design variable into consideration such as
