Cryodata develops calculation software for thermophysical properties of fluids and solids, with emphasis on low temperatures. All properties calculations are referenced to published scientific papers. Directors are Dr. Vincent Arp (varp@cryodata.com) and Robert McCarty (rimfire@ai5.net). Sales are through Horizon Technologies (sales@htess.com).
Software
GASPAK: Calculates 28 different thermophysical properties of 36 different fluids having normal boiling points from 4 K to room temperature. Properties are calculated for temperatures from the triple point to the upper limit of available data for that fluid (range 400 to 5000 K), and for pressures to about 100 bars (different limit for each fluid).

HEPAK: Calculates 33 different thermophysical properties, including superfluid parameters, of Helium-4 from 0.8 K to 5000 K. Coming in 2005: Helium4 properties extended down to zero K and updated throughout the compressed liquid range. New code: Helium-3 properties from 0.005 K to 300 K. Copyright by Vincent Arp.
METALPAK, EXPAK, CPPAK: Thermal properties of 14 nominally pure metals; thermal expansion and specific heats of 37 solid materials. Temperature range 1 to 300 K. Copyright by Vincent Arp.
