Product Features

    ATEX - European Hazardous Area Approval

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

Freezstop Extra is approved for use in non-hazardous, and hazardous areas to world wide standards. Its self-regulating characteristics improve safety and reliability.

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

Freezstop Extra is available with a corrosion resistant thermoplastic outer jacket (FSE-CT) and when greater corrosion resistance is required with a fluoropolymer outer jacket (FSE-CF). 

The installation of Freezstop Extra 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.
