  • Power controller for heat tracing cable which responds to ambient temperature
    Patent number: 4859834
    Abstract: A power controller is provided for controlling the distribution of power to heat tracing cable or the like. Heat tracing cable is used for maintaining a desired process temperature in pipes or vessels when the outside ambient temperature falls below the desired process temperature. Based on outside air temperature the controller of the present invention determines the percent of power which should be supplied to the heat tracing cable network to maintain the temperature. The power controller hereof alters the length of time that power is supplied to the power network to control the amount of heat supplied. Advantageously, the power controller results in significant energy cost savings by supplying only the specific energy required to maintain the temperature in the heating cable network.
