What it does
Three-zone rating
Desuperheat, condense and subcool (or preheat, boil and superheat), with a weighted MTD and the smallest internal temperature difference.
Three services
Process condenser, steam surface condenser, or reboiler / vaporiser.
Pure fluids or mixtures
Pick a fluid from the library, or enter the dew point, bubble point, latent heat and specific heats of a mixture.
Steam condenser results
TTD, ITD, clean back-pressure, excess back-pressure, lost turbine output and its cost; air-blanketing warning.
U, fouling and cleanliness
Actual U, fouling resistance, cleanliness and excess area — and how far a single LMTD would be off.
Charts
Temperature–duty zone diagram and UA by zone, ready to print.
Built for engineers
- Visible formulas — nothing hidden, so you can check every step.
- Fully referenced — methods from the standard references, checked against their published worked examples.
- Safe to share — sheets are protected against accidental edits, with an open password so you can still customise.
- Built-in input checks — clear warnings for impossible inputs and values outside typical ranges.
For engineering estimates; verify against site data. Code-based methods are aligned with the publicly documented procedure; they are not a licensed reproduction or a certification.
