Pipe Freeze Protection

Effective and energy conservative solutions.

Pipe Freeze Protection by Self-regulating Cable

FLN series are designed to provide freeze protection of general water piping, sprinkler system standpipes, and temperature maintenance of greasy waste lines or fuel lines. Applicable to both metallic and nonmetallic pipes.


  • Temperature self-regulating, never over-heating, safe to overlap and insulate
  • Can be cut to lengths and terminated in the field
  • Applicable for both metallic and non-metallic pipes
  • Protection against chemical and mechanical damage with Flouropolymer outer jacket
  • No temperature controller is required
  • Energy conservative
  • CE approved
