    Intelligent Electric Heat Tracing

    Tongxin Heat Tracing Intelligent Control and Energy saving Solution takes "precise temperature control, efficient energy saving, and intelligent operation and maintenance" as its core values. By leveraging the independently developed self-limiting temperature control power supply system it achieves ±1℃ precise temperature control, breaking the limitation of large temperature fluctuations in traditional relay control. The solution is applicable to oil pipelines, storage tanks, valves, pressure regulating stations, gas pipelines, LNG equipment and other places in the petrochemical industry, meeting the needs of different industrial scenarios. The solution utilizes wireless communication to transmit data in real time, dynamically match heating demands with power output, and through AI diagnosis and local visual monitoring, promptly obtain early warnings of abnormal power consumption, leakage, or temperature control failure. It builds an intelligent thermal management network featuring multiple synergies collaboration, promoting the transformation and leap of industrial thermal management from extensive insulation to efficient and low-carbon digital transformation.

      Self-limiting temperature control power supply system 

      Traditional temperature-controlled switch-type constant-power heating tapes or self-limiting temperature heating tapes usually adopt a redundant heating design with a heating temperature higher than the insulation temperature of the pipeline. The higher the pipeline temperature is above the ambient temperature, the greater the heat loss and the more electricity is consumed. 

      The intelligent control and energy-saving embedded self-limiting temperature regulation system of Tongxin heat tracing technology adjusts the output power in real time based on the dynamic changes of pipeline temperature. When it detects a significant deviation between the actual temperature and the set value, it automatically increases the output power to accelerate the heating process. When the temperature approaches the set value, the system automatically reduces the power while maintaining precise temperature control within ±1℃, effectively eliminating the impact of frequent on-off operations of traditional temperature control switches on the power grid, and reducing peak load and energy consumption fluctuations. 

      The self-limiting temperature control system is controlled by an electronic power control module.Unlike traditional mechanical temperature control switches, it does not experience aging or wear, ensuring more stable and reliable temperature control with a longer service life.


      Networking form 
      It is composed of a system upper computer, a gateway, and an explosion-proof electric heat tracing intelligent control data transmission base station. It achieves ultra-long-distance stable communication through LoRa or 4G wireless communication modules, meeting different application scenarios in factories.

      Smart Networking Edition

      Administrators can centrally manage all heating cables through the intelligent management system, which enables linkage analysis and real-time assessment of their operating status. When faults such as open circuit, short circuit, power supply anomaly, pipeline low temperature, or overload are detected, the system immediately triggers an alarm and reports it to the host computer.
