SteamTab Quad sets a new standard in capability and ease of use for steam property generation. SteamTab Quad contains all of the features of SteamTab Duo. In addition, with SteamTab Quad, you can choose from 4 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.

Old Scientific Formulation (NBS/NRC-84): This is the older scientific formulation approved in 1984 and also available in our SteamTab V2 and SteamTab Duo V1 products.

Old Industrial Formulation (IFC-67): This is the older, but widely accepted formulation in the power industry. This formulation is based on the 1967 IFC formulation for industrial use (ASME Steam Tables, 6th Edition).

Using SteamTab Quad 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 Quad could also be used to generate Mollier charts and steam tables in your own choices of units, graduations, or language. Give SteamTab Quad a try to see what it's really capable of!
