Benefit from our 40 year experience in the field of energy engineering!
Between 1970 and 1987 Marin Zeller was in a leading position at various Swiss factories of heat exchangers and air handling units. He developed software applications for the calculation of heat exchangers and their sale.
In 1987, Marin Zeller has founded the single company Zeller Consulting Suisse and developed until 1992 all software programs for the calculation of heat exchangers for a big German factory of heat exchangers.
In 1992 the company has changed the hardware from DIGITAL-VAX mainframes to PCs and the software from Fortran to C++ (AHH, Mollier HX diagram) and Excel (Heat exchanger) and has developed a variety of software programs for the calculation of heat exchangers.
Since 1996, Stanislav Korniliev, programmer, Kiev, Ukraine, complete our team. His specialties include the development of GUI, DLL and the linking under MS Visual Studio.
Since 2005, the most important applications, written in Excel, was further developed to high-level language in combination of Intel Fortran (Source) and MS C# (GUI, Graphical User Interface) under MS Visual Studio. This allows convenient the linking of various program modules (DLL, Dynamic Link Library) which exist in different programming languages.
More than 5000 engineers use our software in 8 languages!
