A quick and easy way to call refrigerant properties.

XProps® is an enhancement to NIST’s REFPROP database, a vital reference for refrigerant properties used throughout the thermal systems industry. XProps® includes all of the physical property routines from REFPROP and has the ability to define unique refrigerant mixtures.

Additionally, XProps®:

  • Supports over 65 different pure fluids and more than 35 built-in fluids and mixtures
  • Includes support for newer fluids such as HFO-1234yf
  • Supports English, SI and mixed units
  • Can access over 112 property function calls from various platforms including:
    • Microsoft® Excel® Version 2003, 2007 and 2010, 2013, and 2016 (32 bit)
    • Microsoft® Visual Basic®
    • C, C++
    • Matlab® version 2006 or higher
    • Engineering Equation Solver (EES)
