trace tubing consists of a process tube traced with
a constant wattage heating cable, a heat transfer
foil wrap, a nonhygroscopic glass fber insulation
and a black, 105° C rated, fame-resistant PVC
(FR PVC) jacket.
Parker CL Constant Wattage Temptrace™ is
designed for various temperature ranges including:
Freeze protection and viscosity maintenance of
50° F (10° C) at ambient temperatures of- 40°F
(-40° C); and low process temperature maintenance
of 160°F (71.1° C) to 250° F (121.1°C) @ -40°F
(-40°C) to 80° F (26.7° C) ambient conditions.
Standard product has a Maximum Temperature
Rating (MTR*) of 400° F (204.4° C), power-off and
250°F (121.1°C) Power on. See CH-Constant Watt
design for higher temperature ranges.
*Maximum Temperatue Rating is the maximum
allowable temperature of the tracing fuid.
Temperatures in excess of this may damage the
product or alter its performance.
