The hidden cost in every steam system

A failed steam trap burns money every hour it keeps leaking

Mechanical steam traps rely on buckets, floats and levers. As those parts wear, they jam open — and your live steam escapes straight into the condensate line.

⛽

76.9 kg of steam per hour

Leaked by a single failed DN25 medium-pressure trap. Over a 7,000-hour operating year, that is 538 tonnes of steam — roughly USD 21,000 — gone from one device.

🧰

Moving parts wear out

Float and inverted-bucket traps typically need replacement within 1–2 years under real plant conditions, plus shutdowns for inspection and maintenance.

🌡️

Process efficiency drops

Leaking steam floods condensate lines, destabilises back-pressure and slows heat transfer — slower heat-up, erratic temperature control, water hammer risk.

The SteamEco answer

A steam trap with nothing inside to wear out

SteamEco uses a precisely engineered venturi nozzle instead of mechanical parts. Flash steam generated in the expansion section creates back-pressure that seals the throat — condensate passes, steam stays put.

  • Zero-to-negligible steam leakage, verified in third-party tests
  • No moving parts — no wear, no jamming, no scheduled overhauls
  • Self-cleaning: flash-steam turbulence keeps the throat clear of debris
  • Immune to water hammer and thermal shock; installs at any angle
  • Stainless steel body, service life 10–20 years, warranty 3–10 years
  • Same flange dimensions as your existing traps — drop-in replacement

Product range

Three series, engineered for different duties

SteamEco SE-D fixed-flow venturi steam trap
SE-D · FIXED FLOW

High-capacity process duty

For heat exchangers, evaporators and distillation reboilers with heavy, stable condensate loads. Multi-orifice internals are easily resized when the process is debottlenecked.

SteamEco SE-Z combined low-capacity venturi steam trap
SE-Z · COMBINED

Steam mains & tracing lines

Venturi + bimetallic combined design for saturated and superheated steam distribution lines. Zero steam leakage, on-line adjustable, filter easy to service.

SteamEco SE-DT adjustable venturi steam trap
SE-DT · ADJUSTABLE

Varying process loads

Flow capacity adjustable on-line for kettles and batch heaters with wide load swings. Spindle geometry preserves the venturi characteristic. Leakage below 0.1%.
