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.

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.

 

The cables feature IPX7 protection rating, which will guarantee anti-shock protection when connected to the power circuit protected with a RCD.
