WinSteam 3.1
WinSteam provides accurate thermodynamic and transport
properties of steam and water for Windows applications using the new IAPWS-IF97
formulations. WinSteam also allows you to select
the IFC 1967 formulations for compatibility with older projects.
The steam property functions can be used directly from within
applications including Microsoft Excel, Lotus 1-2-3 and MathSoft Mathcad.
Add-ins attach the functions so that you can use them as if they were
built in to the applications.
Programmers can call the WinSteam functions from Visual Basic or Visual
C++. WinSteam also includes the stand-alone product DeskTop
Steam, an advanced steam property calculator. If you do not
need to access the steam functions from a spreadsheet, you may purchase DeskTop
Steam alone. |

upgrade to licensed users of WinSteam 3.0.

up to 1450.3 psia (10MPa) . |
| Check pricing for attractive quantity
discounts. |
The WinSteam package includes various add-ins which
link the functions to many popular 32-bit Windows applications.
Add-ins are included for Microsoft Excel Versions for Office 95, Office 97,
Office 2000 and Office XP; Lotus 1-2-3 97 and 1-2-3 Millennium and MathSoft Mathcad
Plus Versions 6, 7 and 8.
No programming is required to use the WinSteam
functions with any of these applications. Just follow a few simple steps
to load the add-in, and from then on, the functions will be available
every time you start the application. You use the functions just like any
of the built-in functions. The functions can be used in any spreadsheet
formula and any argument to the functions can be a number, a formula or a
cell reference.
All of the steam property functions are contained in a Windows Dynamic
Link Library (DLL). The WinSteam package includes a
32-bit version of the DLL, which supports applications designed for
Windows 95, 98, NT, 2000 and XP. Function prototypes and LIB files are
included in the package to support Microsoft C/C++ compilers. Declaration
files are included to facilitate programming with Microsoft Visual Basic
or Microsoft Access.

If you wish to try WinSteam, you may download a fully
functioning copy for a 30 day evaluation period. You may also use
this download as a replacement for a lost or damaged copy of WinSteam
3.1. If you decide to purchase WinSteam you may use the
download and we will provide you with a serial number for permanent
use. The download version is identical to the hard copy except that
it includes an html version of the user's manual (which you can read using
your web browser) instead of a paper copy. Ordering WinSteam
3.1, via download saves you time and shipping costs.
