Reduce Energy Loss by Inspecting Steam Traps with Ultrasound

Steam traps play a vital role in maintaining energy efficiency and system reliability. Using ultrasonic leak detection helps identify failed or inefficient traps that waste energy and contribute to system issues. Regular inspections support optimal performance and long-term equipment reliability.

Steam traps are critical to maintaining energy efficiency, system reliability, and equipment longevity in steam systems. An ultrasonic leak detector survey helps identify failed or inefficient traps that can cause energy losses and lead to potential system issues. Regular inspection and maintenance ensure optimal performance and long-term reliability.

What is a Ultrasonic Leak Detector?

An Ultrasonic Leak Detector is a handheld diagnostic instrument used to detect high-frequency sound waves produced by leaks, electrical issues, or mechanical faults that are inaudible to the human ear. Using the included headphones, the operator can clearly identify whether a steam trap has failed open or failed closed.

What do you hear: Click on Normal trap and Failed-Open Trap to listen to audio.

  • Normal trap: Produces an intermittent cycling sound, allowing you to hear the trap opening and closing as it discharges condensate.
  • Failed-open trap: Produces a continuous high-frequency sound, indicating that live steam is blowing through the trap.
  • Failed-closed trap: Produces little to no sound downstream of the trap, indicating that condensate is not being discharged.

Why Facilities Managers should use a ultrasonic leak detector:

  • No system shutdown required: Steam traps can be inspected while the system is fully operating.
  • Bypass valve verification: Ultrasonic detection can confirm leaks through bypass valves.
  • Failure prevention: Helps prevent system failures, water hammer, and equipment damage.
  • Improved efficiency: Replacing failed steam traps improves overall system efficiency and reduces energy loss.
