Information
PX-F Series Self-Regulating Cable
Pipe Freeze Protection
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 efficiency 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 field, simplifying the installation process and reducing waste
• Rugged 16 AWG bus cable with longer runs
• Wide variety of wattages
• Limited ten year warranty
