nVent RAYCHEM ETL Self-Regulating Heat Cables for Pipe Freeze Protection
nVent RAYCHEM ETL self-regulating heat cables keep pipes from freezing in buildings, both indoors and outdoors.
Product Features
- Can be cut to the correct length on-site.
- Compact size facilitates installation.
- CR-sheathed heat cable can be installed on the outside of the pipe, and CT-sheathed cable on both the outside and inside.
- Models with 10 W/m and 16 W/m power output for various pipe diameters.
- Completely maintenance-free after installation and commissioning.
- No risk of overheating thanks to self-regulating technology.
Self-Regulating Technology
ETL cables are based on self-regulating technology. The power output automatically adjusts at different points along the cable according to the ambient temperature. The cable will never overheat, even if installed in a crossed configuration.

Easy Planning and Installation
Unlike standard resistance heat cables, the planning and cutting of ETL cables to the correct length can be done on-site. The heat cable is terminated with an end-seal kit at the end of the pipe. For efficient operation and complete peace of mind, a wide range of manufacturer-designed, tested, and approved connection and electrical accessories are also available for the heat cables.
