eltherm ELSR-N-Halogenfrei
Heating cables and assemblies · Pipe freeze protection
ELSR-N-Halogenfrei is a distinct low-temperature version for building-services applications. Where a project specifies halogen-free construction, the actual cable version must be documented. Pro Therm coordinates that requirement with heat loss and installation conditions.

A self-regulating cable’s output depends on temperature. Heat loss and the cable output curve must be compared under matching conditions. Cold start, maximum circuit length and protection are assessed separately. Self-regulation does not replace the review of controls, electrical protection and permitted operating conditions.

Can I enquire about this product directly?
First specify the version and quantity in the product finder. For heating cables, provide voltage and output or explicitly request technical selection. Then enter your contact details and submit the form.
Can another manufacturer’s product be considered?
An alternative may be offered after technical review. Output, temperature limits, connections and existing system requirements are assessed together. Cross-brand interchangeability is not assumed.
