Reactor multipoint systems are among the most complex and important temperature measurement systems in use today in the global process industries. Commonly implemented in fixed-bed and tube sheet reactors alike, multipoint thermocouples provide the critical temperature data that operators rely on to run each unit safely and efficiently.

Well-designed and correctly installed multipoint thermocouple systems will monitor the condition of the catalyst and the performance of the reactor internals and act as an alarm system for process anomalies such as channeling and hotspot development. In order to perform this function successfully, multipoint systems must be installed with great care and precision to ensure each sensor is securely installed at the correct location as predetermined by the plant and process licensor. Installation expertise is also critical to ensuring our CatTracker® thermocouple system achieves a full service life (10+ years for most applications).

To help you better understand what to expect when executing this type of work, here is walk-through of a typical reactor multipoint installation project led by our field team:

Phase 1:

  • Coordination meeting to establish contacts, schedule, contractors, etc.
  • Preliminary visual inspection/inventory
  • Pre-job walk of vessel(s)
  • Discovery item support

Phase 2:

Phase 3:

  • Support during catalyst loading/changeouts
  • Post-installation documentation submittal (As-Installed Drawings, Final Inspection Reports, etc.)

We understand that each outage and each application is unique, and our field services team would welcome the opportunity to discuss the specific needs of your next reactor multipoint installation project.
