selftec_dw

 

ELEKTRA SelfTec®DW self-regulating heating cables. Multi-purpose antifrost protection system, for applications both outside and inside of pipes. Certified for drinking water applications.

In-pipe installation enables anti-frost protection of:

  • pipelines under operation, with no necessity of removing insulation,
  • underground pipelines.

 

twin-conductor shielded pvc-free multi-wire-conductor halogen-free

 

 


 

Features

The 10 and 16 W/m cable output (at +10°C) was especially selected to account for the water heat capacity.

Available in a double layer polyolefin + LDPE sheath(SelfTec®DW), as well as a single layer fluoropolymer sheath (SelfTec®DW F). Certified for food contact applications, allowing for the in-drinking water pipelines applications.
