Glycol heat tracing is used to protect piping, boilers, pumps, and other industrial plant equipment from freezing. It utilizes a closed-loop circulation system of tubing containing heated glycol to transfer the heat from the traced lines to the process piping. Glycol tracing is used in winterization processes at oil and gas refineries to prevent freeze damage and keep process lines at the required temperature.

If a system or equipment is exposed to prolonged freezing temperatures, the result can be costly damages and ineffective processes. Glycol heat tracing ensures freeze protection is in place and that all equipment will operate at its optimum peak performance. The problem with glycol tracing is waste. If not properly controlled, you could be wasting thousands of dollars on these systems.

HAT or TV/HAT valves are placed at the end of trace lines to regulate glycol return temperature, which helps to provide the correct flow of glycol for optimum energy use, thus eliminating waste. These self-operating valves sense fluid temperature to modulate the valve open and closed to a set discharge temperature. HAT valves are available in NPT, and TV/HAT valves have tube fitting connection ends.

Protecting pipelines and equipment from extreme weather conditions is essential for plant operation and performance. Glycol heat tracing is ideal in areas with frequent cold weather, and ThermOmegaTech’s temperature control valves are crucial in managing these systems. Easily installed at the end of trace lines, these temperature-activated valves automatically sense and regulate glycol temperatures to provide the optimal amount of heat needed for processes and maintain the correct glycol viscosity.
