eltherm ELTC-10 compact / ELTC-M25
Controls and panels · Pipe freeze protection
ELTC-10 compact and ELTC-M25 are control options for freeze-protection applications. The appropriate device depends on the installation arrangement and electrical load. When replacing a unit, Pro Therm also considers whether it switches a self-regulating cable and the resulting switching conditions.
