SRF

• SRF Self-Regulating Heating Cable / Freeze Protection for Pipework
• FINE SRF Series for freeze protection generates heat by a material of semi-conductor,
  showing a characteristic of PTC (Positive Temperature Coefficient).
  
  PTC is characterized by the power output of heating cable adjusted to compensate for variations in ambient temperature.
  It produces more heat if the temperature drops and less heat if the temperature rises.
  
  SRF Series is a self-regulating cable heater, working on the PTC principle, requiring low electrical consumption.
  
  SRF Series is most suitable for protection of plumbs and pipes from freezing in winter.

Product construction

• 1. Copper bus wire(16AWG)
  2. Self-regulating conductive core
  3. Inner adhesive jacket
  4. Modified polyolefin jacket
  5. Tinned-copper braid
  6. Modified polyolefin outer jacket (-CR)
      Fluoropolymer outer jacket (-CT)

Features of FINE SRF Series

1. Long life time (semi-permanent)

• SRF Series is post-treated under elevated temperature in annealing process to give its stability in long-term operation without losing heat output.

2. Low energy consumption

• The electrical consumption of SRF Series is low due to its unique PTC property.

3. Excellent heat resistance

• SRF Series is treated by irradiation crosslinking reaction, providing the same level of thermosetting property as XLPE.

4. Cut to length

• The heat generator of SRF Series is composed of the infinite parallel connection of carbon particles, allowing it to be cut to the exact length required.
