This complimentary calculator is provided for all to use but it receives minimal support. We recommend that you DO NOT use it:
- As a resource called by other software for property data
- In any critical application
If you require a reliable source of thermodynamic properties,
we recommend you obtain a copy of EES (Engineering Equation Solver) from www.fchartsoftware.com or REFPROP from www.nist.gov/srd/refprop. CoolProp (www.coolprop.org) is an open source C++ library which works well in many applications.
