Freezstop Micro (FSM)
Freezstop Micro is an industrial grade, self-regulating heating tape that can be used for freeze protection or temperature maintenance of pipework and vessels. It is particularly suited to small diameter pipes and instrument tubing such as impulse or analyser lines. It can be cut-to-length on site to match exact piping lengths without any complicated design considerations.
Freezstop Micro is approved for use in non-hazardous and hazardous areas to worldwide standards. Its self-regulating characteristics improve safety and reliability. Freezstop Micro will not overheat or burnout, even when overlapped upon itself. Its power output self-regulates in response to the pipe temperature.


Example of Applications
- Freeze protection of pipework & vessels
- Process temperature maintenance
Benefits
- Can be cut to length
- Suited to small diameter pipes and instrument tubing
- Output self-regulates in response to pipe temperature
- No overheating or burnout

Freezstop Micro is available with a corrosion resistant thermoplastic outer jacket (FSM-CT) and when greater corrosion resistance is required a fluoropolymer outer jacket (FSM-CF) - see image to right.
The installation of Freezstop Micro is quick and simple and requires no special skills or tools. Termination, splicing and power connection components are all provided in convenient kits.
