TSR
Self-Regulating Pipe Tracing Heating Cable
Specification/Application Guide
READ CAREFULLY
PRINCIPLE OF OPERATION
Easy Heat TSR is a self-regulating heating cable that automatically
varies its heat output with changes in surrounding temperature.
Since this cable regulates its heat output with temperature,
a thermostat may not be necessary for some applications.
Easy Heat TSR cable can be used for pipe freeze protection or
temperature maintenance applications, in either ordinary or
hazardous (CID2) locations. TSR cable is also available with fluor-
opolymer overjacket for use in areas requiring enhanced chemi-
cal resistance. TSR cable with fluoropolymer overjacket is suitable
for maintaining grease and fuel lines at temperatures required for
flow conditions.
The TSR cable is available with power densities of 3, 5, 8 and 10
Watts per foot. This power is specified at a surrounding tempera-
ture of 50
F. At other temperatures, of course, the cable power
o
output will be considerably different. (See chart).

Because of the self-regulating feature of this cable, it can be
wrapped over itself (overlapped), if necessary, when installed on
pipes, valves or flanges.

TEMPERATURE “PILINg” IN When heating cables are to be insulated with foamed, mudded VERTICAL INSTALLATIONS or poured insulation, the cable must be covered by foil. This is to heat from temperature-maintained air and fluid rises. In a vertical prevent the cable from being thermally isolated from the pipe.
