SDT340 for Steam Traps and Valves: What One Blow-Through Really Costs
Up to 30% of traps fail without surveys. Fixing one thermodynamic leak can save ~€2,500/year; a stuck-open float at high pressure can exceed €7,000. How SDT340 + UAS3 turn ultrasound into predictive steam maintenance.

Without regular surveys, up to 30% of traps fail. SDT cites ~€2,500/year saved by fixing one leaking thermodynamic trap and >€7,000/year for a stuck-open float at higher pressure.

How to test a steam trap: ultrasound and temperature
A steam trap is tested with two readings: temperature finds blocked traps, ultrasound before and after the trap finds steam blow-through. Signs by trap type, the procedure and steam losses.
