Abstract:

Embodiments of the invention provide an electric heat trace (EHT) control system for use with a piping system having pipes and capable of transporting a fluid. The EHT control system includes an EHT circuit for heating the piping system, a temperature sensor outputting a temperature value, a flow status sensor outputting a flow status value, and an EHT management system. The EHT management system can include a controller connected to the EHT circuit in order to selectively energize the EHT circuit. The controller can be connected to the temperature sensor in order to receive the temperature value and the flow status sensor in order to receive the flow status value. The controller can be configured to execute an EHT management program including the steps of receiving the temperature value, receiving the flow status value, and utilizing the temperature value and/or the flow status value to determine whether or not to energize the EHT circuit.
