Heat Tracing Questions

1. Why the heat tracing cables draw more current during starting at start up temperature?

2. How self regulated tracing cables are inherently safe and can be used in hazardous area?

3. How the Maximum circuit length is determined according to the breaker type? What is the equation used here? (see the picture below)

  • XX  Frost Protection Heat Tape
    Prevents water from freezing in metal and plastic pipes


    The PW’s built-in thermostat means that no additional control device is required.


    The PW Frost Protection Heat Tape is designed for use

    for the positive protection of hot and cold water pipes that may be subject to freezing conditions.


    This can be used in flats, houses, mobile homes, farms, sports pavilions,

    both for water supply and fire protection sprinkler systems.


    The simple self contained nature of the XX lends itself to use for the

    protection of single pipes such as in domestic lofts or gardens, for use with condensing boilers and widely used on mobile homes.


    It is also ideal where many identical pipes require to be protected ie. In blocks of flats or sprinkler networks.
