Heat exchangers
Rating and design with data sheets.
Use this add-on:
Screenshots and a short video come with the listing (AL.3).
Overview
Planned. This add-on is not built and no host app mounts it. Heat exchangers is planned (roadmap row CH.8) as rating and design with a data sheet, a tube-sheet drawing in CadCraft and the exchanger as a PartCraft body. A rating library exists in the lab; no app uses it yet.
Who it’s for
- Process engineers who rate or size exchangers.
- Mechanical designers who draw tube sheets and bodies.
What you can do
- Nothing works yet. Planned: LMTD and effectiveness-NTU rating, shell-and-tube rating with tube-side and Kern shell-side calculations, tube layout and a tube-sheet drawing, air coolers, plate exchangers, and a tube vibration screen (CH.8).
Methods and standards
Planned from published correlations. The roadmap target is Bell-Delaware rating; the library has the Kern method today and notes that Bell-Delaware is not built because no source for its coefficients was at hand.
Data and sources
Fluid properties come from the process model. A plate exchanger needs the maker's pattern constants, which are never defaulted.
Verification
Planned: no add-on test yet. The engine library behind it has a test, tools/process-test/test-equip.mjs, which the session log chem-equip_PART_3 records as 119 passed, 0 failed on 2026-10-28. It checks closed forms and consistency identities, not a printed shell-and-tube example. The log says the typed tables and constants still need an engineer's check against the standards.
Limits
Not built: Bell-Delaware, kettle and reboiler types, condensing and boiling coefficients, multiple shells, TEMA mechanical design, the CadCraft tube-sheet command, and the PartCraft body. The tube-sheet SVG exists only in the library.
Files and formats
Planned: a data sheet and a tube-sheet drawing. Nothing is written today.
Get started
- Nothing to open yet. The add-on is planned and cannot be added.
- Watch the roadmap row named in this listing for when it is built and enters the lab.
