Calculation software for the VDI Heat Atlas / 12th edition

LV – Software based on the calculation sheets for heat transfer (Springer Verlag Berlin, formerly VDI-Verlag Düsseldorf) For more than half a century, the VDI Heat Atlas has been a reference work in process engineering. For more than 30 years, you can apply its methods quickly and easily with our programs. The contents are regularly reviewed and supplemented by VDI experts on the basis of established data and the latest scientific findings. This means that you can always rely on being up to date with the latest technology with the VDI Heat Atlas and the LV programme. In the currently published 12th edition, several correlations, some of them fundamental, were adapted to the current state of research and some chapters were completely revised .These changes were adopted in our new programme version 8.33. In addition, the VDI Heat Atlas was expanded in various sections. New calculation approaches were implemented – partly as new modules, partly as supplements to existing modules. The new programme version thus gives you even greater flexibility, e.g. when designing your heat exchangers. Here you can now calculate, for example, pressure loss and heat transfer for further innovative baffle geometries to obtain even more efficient exchangers. This opens up new possibilities for you and also fulfils the current standards with future designs.

Development of the VDI Heat Atlas

The first edition was published in 1956 as a book by VDI-Verlag. The VDI Heat Atlas, the standard work in Europe for the calculation of heat transfers, physical properties and flow problems, is now available in its 11th edition. Its structure concentrates on a comprehensive theoretical description of the most important basic process operations on which the various processes are based. Many authors from research and industry have contributed to the preparation of the individual chapters and sections. A German version (12th edition) is available as a text part (book or eReference)and can be arranged by us at a favourable price.

What can the LV calculation program do?

Since the 5th edition, the individual chapters have been licensed as calculation programs by Lauterbach VT and have always been adapted to the current editions. Currently the programs run under Windows 10 / 32 and 64 bit.. There is also an English full version of the German program LV-VDI-Wärmeatlas. The ATLAS modular system made the practical application of the chapters and their combinations into processes much easier. Each chapter corresponds to a module. These modules can be integrated into the individual problem,e.g. in MS-Excel,and extended by own calculation equations. Individual modules are mapped in individual tables, the reference of the respective variables is established by simply dragging the mouse.


  1. The VDI Heat Atlas is interactively available to the user.
  2. The equations are displayed with the current input values.
  3. The data of the individual chapters can be connected by simply dragging and dropping them.
  4. General options of the ATLAS program system are available
