Heat Trace Tape Control for HVAC Piping

Heat Trace Tape Control for HVAC PipingHeat Trace Tape Control for HVAC Piping

HVAC Piping systems especially in the Northern regions need a way to freeze protect piping the runs outdoor which is a necessity in many different HVAC application. To protect HVAC piping from freezing heat trace tape is wound around the pipe and controlled by an outdoor thermostat or temperature control that energizes the heat trace tape and keeps the pipe from freezing. Heat trace tape looks similar to Romex and simply provides electrical resistive heating for the pipe. Heat trace tape is made of many layers that begins with the heat trace wire. The wire inside the insulation (typically 16 AWG) that heats up is surrounded by a conductive core. The conductive core is surrounded by a thermoplastic insulation. This has an outer copper overshield that is also in a thermoplastic insulation as an outer jacket to protect the inner layers of the heat trace tape. The photo shows a heat trace tape temperature controller that energizes the heat trace tape to protect the piping from freezing. In this particular case, the temperature controller controls the heat trace tape on a chilled water piping system and a hot water piping system. Tanks can also be wrapped with heat trace tape and then insulated for further protection. (more…)
