NIST offers a legitimate, free sample version called mini-REFPROP . It is designed for students and includes only a few common fluids like water, methane, and nitrogen.

CoolProp is an open-source C++ library that provides a vast array of thermophysical properties for pure fluids and mixtures. It was originally developed by Ian Bell and is now maintained by an international team of contributors. CoolProp is not just an imitation; it's a powerful tool in its own right, using many of the same high-accuracy equations of state that are found in REFPROP. refprop 91 free
