System Overview
The XL-Trace system provides freeze protection and flow maintenance for aboveground
and buried pipe applications . The XL-Trace system is based on self-regulating heating cable
technology . Tyco Thermal Controls offers the option of three self-regulating heating cables
with the XL-Trace system: 5XL, 8XL, and 12XL (208–277 V only) for applications using 120 and
208–277 V power supplies . The cable’s output is reduced automatically as the pipe warms,
so there is no possibility of failure due to overheating .
An XL-Trace system includes the heating cable, power connection, splice, tee connections,
controls, contactors, power distribution panels, accessories, and the tools necessary
for a complete installation .
