Heat tracing

Electrical heat tracing is used for keeping pipelines and vessels on a stable temperature, and to prevent freezing. We specialize in both reliable and accurate control systems for this kind of application.

Benefits of RKC Instrument temperature control:

  • very accurate temperature control that reacts fast to process changes
  • superior noise rejection on temperature measurement signals
  • effective over- and undershoot suppression with advanced adaptive PID control algorithms
  • reliable instruments, MBTF times > 40 years

We have solutions for local control near the pipeline or vessel, or centralized control from a controlpanel in a central control room.

Controllers can be coupled to a PLC/DCS system via the fieldbus, or controlled from an optional available HMI/SCADA touchpanel
