Failed steam traps waste energy, reduce process efficiency, and can cause equipment damage. Regular trap monitoring identifies failed traps (stuck open, wasting live steam, or stuck closed, causing waterlogging) before they impact operations. Studies show 15-30% of steam traps in a typical plant are malfunctioning at any time.
AQ Process Systems sources and exports portable testing equipment for manual trap surveys (ultrasonic, temperature, and visual methods) and permanent inline monitoring systems for continuous trap status tracking. Wireless monitors enable real-time trap health dashboards for energy management.
We also provide steam trap survey services, our trained engineers survey your installed trap population, identify failed and underperforming traps, calculate steam losses, and recommend replacements with payback analysis.

Studies consistently show that 15-30% of steam traps in a typical plant are malfunctioning, either stuck open (wasting live steam directly to condensate) or stuck closed (causing waterlogging, reduced heat transfer, and potential water hammer). A single failed-open trap can waste thousands of dollars worth of steam per year. Regular monitoring identifies failures for prompt repair.
Three main methods: visual (observing discharge through a test valve, flash steam indicates working, continuous blow indicates failed-open), ultrasonic (listening to the trap's acoustic signature, different patterns for working, failed-open, and failed-closed), and temperature (comparing inlet and outlet temperatures, similar temperatures suggest failed-open). Professional surveys combine all three methods.
Wireless monitoring systems place battery-powered sensors on each trap that periodically measure temperature, vibration, or acoustics and transmit the data wirelessly to a central system. A dashboard shows the status of every trap in the plant, enabling predictive maintenance and immediate identification of failures without manual surveys.
Best practice is to survey all traps at least annually. Critical traps on high-value equipment may warrant more frequent checks or permanent monitors. Some plants survey quarterly. The frequency should be based on the age and condition of the trap population, the value of steam losses, and the criticality of the equipment served.
Typical payback is 3-12 months. A single failed-open 1/2" trap on a 10 bar system can waste 25-50 kg/hr of steam, costing $5,000-$15,000/year. With 15-30% of traps failing, the total steam loss in a medium plant can be significant. The cost of testing, repair, and monitoring is a fraction of the steam savings.
