Freeze Free heating cable is self-regulating pipe heating cable that automatically varies its heat output with changes in surrounding temperature. Since this cable regulates heat output with temperature, a thermostat may not be necessary for some freeze protection applications. Freeze Free cable helps keep plastic and metal water pipes from freezing to -60ºF/-51ºC. A braided metal jacket provides an electrical ground as well as protection against damage in dry locations. Freeze Free can be cut to desired lengths per application. 75-foot maximum circuit length, 3-foot minimum circuit length.
Freeze Free cable can be applied on water-filled metal or rigid plastic pipes up to 2" (50.80mm) in diameter. On smaller size pipes, the cable can usually be applied straight along the pipe. However, on longer pipes and especially at lower temperatures, the cable must be spiraled around the pipe. This ensures adequate heat is applied to the pipes to keep them from freezing. Because of the self-regulating feature of this cable, it can be safely wrapped over itself (overlapped), if necessary, when installed on pipes, valves or flanges.
The Easy Heat Freeze Free cable is available with a power density of 3 Watts per foot. This power is specified at a surrounding temperature of 50 degrees F. At other temperatures, of course, the cable power output will be considerably different.
