Ashrae Duct Fitting Database Version 60 Free Download Full Install
Version 60 is not just a standalone reference. It acts as a data engine for other tools:
| Software | Integration Type | Benefit | |----------|----------------|---------| | Carrier HAP | Direct coefficient lookup | Automatic C-value insertion in system tree | | Trane Duct Designer | Export/import via XML | Real-time static pressure recalculation | | Elite Software DuctSize | Native database link | Updates all fittings when changing duct material | | Autodesk Revit | Add-in manager | Calculates pressure drop in mechanical schedules |
If your installation fails to integrate with a specific tool, run the IntegrateDB.exe utility found in the installation folder. This resets registry keys and COM references.
Version 60 may be one of the last standalone local databases. ASHRAE has announced that Version 70 (expected 2026) will be cloud-first, requiring an annual subscription and real-time internet access. While this will provide instant updates and collaborative editing, it also means that Version 60 represents the final "perpetual license" release.
Thus, securing a full install of Version 60 today—legally and permanently—is an excellent long-term investment for any HVAC professional.
Yes. While version 7.0 (paid) includes CFD-validated data for spiral flat-oval fittings, v6.0 remains the gold standard for 95% of commercial HVAC work—rectangular, round, elbows, tees, and transitions.
