5. 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.
5.1. Controls of pipeline heating systems
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:
ELEKTRA UTR60-PRO
controller
for on-pipe mounting, load 16A,
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 the range of
-40°C up to +120°C.
Adjustable hysteresis allows to define
precision of temperature measurements.
Note:
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.
