Custom

Our standard tools cover the equipment most engineers size every day. Standard tools have limits by design — they are built around the assumptions that hold for a defined geometry and a defined duty, and they are faster and safer for being so.

Custom Software is for the requirement that falls outside them: a multi-stream exchanger that has to be solved as one network rather than a series of two-stream units; simultaneous boiling and condensing in a single body; cryogenic or supercritical behaviour where properties change faster than a mean-property method can follow; non-Newtonian and slurry rheology; fouling-life prediction that turns a clean-duty rating into a maintenance interval; and optimisation across a whole exchanger network, where the best answer for one unit is rarely the best answer for the plant.

We also build tools that fit an existing way of working — a calculation your engineers already trust, wrapped so the whole team can run it the same way; a sizing routine tied to your standard data sheet; or a rating tool that reads the tag list you already maintain, rather than asking someone to retype it.

Each tool is written from the same first-principles thermal-hydraulic basis as the standard suite, with every intermediate result — film coefficients, fouling margins, pressure drop breakdown — visible and defensible in a design review. If it is not one of our standard categories, that does not mean we cannot build it. It means it is exactly the kind of project Custom Software exists for.
