Controls
Properly selected controls will ensure efficient and
at the same time economical operation of the
heating system. Self-regulating heating cables
always consume some amount of electric power,
even in temperatures above 0°C, therefore
application of a controller will ensure switch off
of the heating circuit, when required. Controllers
maintain the heating system on stand-by,
switching it on only when necessary.
Due to a high value of inrush current of
self-regulating heating cables, it is
recommended to provide power supply
to heating circuits through a contactor.

Controls of pipeline heating systems
ELEKTRA UTR60-PRO controller
When heating pipelines with heating cables, it is
recommended to apply temperature controllers
equipped with temperature sensors mounted on
the pipeline surfaces. The controllers below will
optimally serve this purpose:
for on support bracket mounting, load 16 A,
the maximum total power of directly connected
self-regulating heating cables is 1200 W.
The controller is equipped with a temperature
sensor for on-pipeline mounting, operating within
