jacket.
Parker CH Constant Wattage Temptrace™ is
designed for various temperature ranges including:
Process temperature maintenance of 160°
at -40° F (-40° C) ambient temperatures , to 400°F
(204°C) at 80°F (26.7°C) ambient. Contact the factory
for complete design capabilities for your application.
Standard product has a Maximum Temperature
Rating (MTR*) of 400° F (204.4° C), Power-On.
Consult Division for details.
*Maximum Temperature Rating is the maximum
allowable temperature of the tracing fuid
Temperatures in excess of this may damage the
product or alter its performance.
