SteamTab Duo

SteamTab Duo sets a new standard in capability and ease of use for steam property generation. In addition, with SteamTab Duo, you can choose from two different formulations to base steam property calculations:
Scientific Formulation (IAPWS-95): This is the formulation approved by the International Association of the Properties of Water and Steam (IAPWS) in 1995 for general and scientific use. This formulation is more thermodynamically rigorous, accurate, and applicable over wider range of conditions.
Industrial Formulation (IAPWS-IF97): This is the IAPWS approved formulation of industrial and special use. The industrial formulation is based on an approximation of the scientific formulation and is generally used in situations where computational speed is of importance.
Using SteamTab Duo in a spreadsheet allows you to examine a large number of design scenarios for optimization and visualize the results in great looking tables and charts.
SteamTab Duo could also be used to generate Mollier charts and steam tables in your own choices of units, graduations, or language. Give SteamTab Duo a try to fully assess its capabilities!System requirementsMS Excel
Limitations in the unregistered versionThe SteamTab Duo demo is limited in temperature and pressure for both the Scientific (IAPWS-95) and the industrial (IAPWS-IF97) formulations. The temperature and pressure limitations of this demonstration package are:
150 <= Temperature <= 200 ºC, and
5 bar <= Pressure <= 10 bar
If you specify a temperature or pressure range that is outside the demo range, SteamTab Duo will return the #VALUE! error in Excel versions or the ERR error in Lotus versions. Also, the SteamTab Duo demonstration package contains only the compressor template that illustrates a steam compressor design.
