New Design Exhaust Thermowell



Did you know exhaust thermocouple failure is the number one cause of trips by five to one over any other trip?  This includes the entire balance of plant and bleed heat valves.

Benefits of the Open Air Exhaust Thermowell:


  • Uses your existing thermocouples

  • Designed for thermal expansion of thermowell keeping the thermocouple solidly attached to the seating surface through start-up and full operation

  • Installation is consistent with use of a strain relief nut

  • Thermocouple floats within the thermowell keeping stresses off the thermocouple casing allowing for maximum life out of the thermocouple

  • Strain relief nut provides support at electrical cable connection

  • Increase availability and reliability of your turbine


The gas turbine is required to be shut down to replace a thermocouple. The cost of replacing the thermocouple in an hour is approximately: $17,500 – lost power generation revenue and $10,000 – combustion turbine fuel startup = $27,500.

GTSP’s “New Design Exhaust Thermowell” will increase availability and reliability for your turbine.  For any additional questions, feel free to contact me.
