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. PYroMat (http://www.pyromat.org) is a limited but all-python open source property calculator as well.
