Heating cable ELSR-M

Self-regulating heating cable Eltherm ELSR-M

ELSR-MThe heating cable ELSR-M is very flexible and is used for special applications where installation dimensions are needed to be kept small. It is particularly suited for short heating circuits. This heating cable can be used for frost protection and temperature maintenance up to 65 °C.

Technical benefits

  • Two nominal outputs
  • UV-resistant
  • Moisture proof
  • Small dimensions
