Product Features

ATEX - European Hazardous Area Approval

FailSafe+ is an industrial grade self-regulating heating cable that can be used for freeze protection or temperature maintenance of pipework and vessels up to 225ºC. It can be cut-to-length at site to match exact piping lengths without any complicated design considerations. 

FailSafe+ can be provided with a continuous metal outer jacket which is ductile, yet withstands high mechanical loads, thus averting damage when installed in arduous environments. Its self-regulating characteristics improve safety and reliability.

FailSafe+ will not overheat or burnout, even when overlapped upon itself. Its power output self-regulates in response to the pipe temperature.

FailSafe+ is also available with a fluoropolymer or silicone rubber outer jacket when greater corrosion resistance is required. 

The installation of FailSafe+ is quick and simple and requires no special skills or tools. Termination, splicing and power connection components are all provided in convenient kits. See Product, Application and Documentation Links below.
