Pipe Freeze Protection

Warmup cables are designed to protect PVC and metal pipes, ceramic drains and sprinkler lines in standard and hazardous environments.

Pipe Freeze Protection

In cold climates, it is necessary to plan ahead to ensure that pipes, sprinkler systems, and sewer drains do not freeze. Warmup self-regulating cable is a perfect solution for these applications because it regulates its output depending on the ambient temperature, making it more energy-efficient to run. Warmup self-regulating cable is well suited for both residential and industrial applications and can be installed indoors and out.

How does it work?

Warmup cables are built with two copper conductors separated by a polymer matrix that expands and contracts with the ambient temperature. This, in turn, varies the output of the cable, so that the colder it gets, the more heat it puts out. Cables are secured to pipes in linear or spiraling fashion and connected to automatic temperature controllers.

Controllers

While self-regulating cables vary the output automatically, adding a controller is recommended to turn off the system in above-freezing temperatures. A simple TRF-115 controller will activate and turn off the system above/below 40 degrees and switch smaller runs up to 22 amps. The TRACE-2 controller will provide GFEP protection to the circuit and handle up to 30A runs.
