Browse to your portable REFPROP.xla file. Note: You may need to update the path within the Excel add-in to point to the portable REFPROP.DLL file rather than a system-installed version. REFPROP 9.0 vs. REFPROP 10.0
For engineers and researchers in thermodynamics, the (Reference Fluid Properties) database is the gold standard for calculating thermophysical properties of industrially important fluids. While version 10 is the current stable release, many legacy systems and specific workflows still rely on the robust REFPROP 9.0 .
To use the REFPROP Excel Add-in (e.g., REFPROP.xla or REFPROP.xlam ) portably: Open Excel. Go to File -> Options -> Add-ins. Click "Go" next to Manage: Excel Add-ins. refprop 9 0 portable
Test the portable copy by running REFPROP.EXE directly from the USB drive on a different computer. The program should launch and function normally, as the NIST installer does not require a key or other security item to run the program.

One of the most powerful features of REFPROP is its dynamic-link library (DLL), which allows the software to be called from external applications. This enables seamless integration with MATLAB, Excel, VB, Python, LabVIEW, and other programming environments and engineering tools.
CoolProp is an open-source thermophysical property database and library that offers similar functionality to REFPROP. It was originally developed by Ian Bell, a post-doctoral researcher at the University of Liege in Belgium, and has since grown into a community-driven project. REFPROP 10
based on advanced Helmholtz energy formulations.
While the software itself is a titan of calculation, the specific iteration of "REFPROP 9.0 Portable" represents a unique intersection of high-level scientific rigor and modern workflow flexibility. It transforms a stationary, lab-bound powerhouse into a mobile toolkit, allowing the laboratory to travel to the field, the boardroom, or the classroom.
: 4.5/5 stars
NIST REFPROP 9.0 is widely considered the industry "gold standard" for calculating the thermophysical properties of fluids. While officially distributed as a Windows-based installation, many engineers use it in a "portable" fashion by calling its core from external environments. Key Performance Highlights
It prevents version conflicts if you need to run REFPROP 9.0 alongside newer versions (like REFPROP 10.0) on the same machine. Core Components of a Portable REFPROP Folder
