Heating cables ELSR-M-BF
Self-regulating heating cables Eltherm ELSR-M-BF
ELSR-M-AF/BF is suited for freeze prevention in pipes and pipelines with seasonal exposure. Typical applications are water supply systems and sanitary facilities on building sites, outdoor events, winter markets etc.
This self-regulating heating cable is used in various industries, mainly in food processing, to protect against freezing, maintain the process temperature of lines, tanks with drinking water or other liquids.
It can be laid inside pipelines. Well suited for short heating circuits. The cable is cut into sections of the required length within the maximum permissible
Construction of Eltherm ELSR-M-BF
1. Bus wire (nickel plated copper).
2. Self-regulating heating element.
3. Insulation.
4. Protection.
5. Outer jacket.
