What it does
Wet gas done properly
Water content from dry, saturated, mol % or intake-air relative humidity; dew point, outlet humidity and condensate (knock-out) load.
Sensible plus latent duty
Weighted MTD over the condensing curve, F factor, U, fouling resistance and cleanliness.
Any gas
A pure gas or a mixture from the fluid library; flow as mass or Nm³/h, wet or dry.
Next-stage power
Extra compressor power when suction is warmer than design, and its yearly cost.
Clear checks
Approach, condensation and input warnings with ranked findings.
Print-ready report
Inputs, results, findings and charts on A4.
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.
