What it does
Test evaluation
Duty, heat balance, LMTD, actual U, fouling resistance and cleanliness from plant readings.
Clean prediction from geometry
Channels per pass, hydraulic diameter and the Martin chevron-plate correlation — or your own correlation.
Clean U and duty
Film coefficients, clean U and clean duty by effectiveness-NTU.
Pressure drop
Channel and port pressure drop compared with the measured values.
Fluid library
About 165 fluids, including glycols, brines and heat transfer oils.
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.
