Data Sheet PX-F Series Self-Regulating Cable
Pipe Freeze Protection
General
Information
Technical Data
The Danfoss PX-F self-regulating heating cables
provide the solution to basic freeze protection
applications. The self -regulating Danfoss PX-F
series ensure maximum energy eciency by producing heat only when and where it is needed as it
adjusts the power output to the varying conditions
along the length of the pipe.
• Cable can be overlapped without creating hot
spots or causing a burn out
• Can be cut and spliced in the eld, simplifying
the installation process and reducing waste
• Rugged 16 AWG bus cable with longer runs
• Wide variety of wattages
• Limited ten year warranty
Available power outputs:
Cable Diameter: 0.45 x 0.216” (11.5 x 5.5 mm)
Rated voltage: 120V-277V
