Full Windows support with the appropriate operation. You no longer need to learn any code numbers for program control. You can select, from easily understandable lists, which variants the program should calculate. Now with more attractive lists and graphics, which can be printed to standard Windows printers or inserted via the clipboard into other programs. Also graphics can be zoomed or moved.
Graphical illustration of the emission course.
The program is present in German and English.
This program is an integrated implementation of the guidelines VDI 3783 part 2 (dispersion of heavy gases in source vicinity) and VDI 3783 part 1 (dispersion of light gases as well as heavy gases in bigger distance to the source).
Because of the linking of both guidelines, for heavy gases the lower ignition distance as well as the concentration on any receptor points can be calculated.
For material and receptor point lists ambient air concentration courses, maximum concentration and maximum dose can be calculated.
The pollutant list of the guideline VDI 3783 part 2 is integrated in the program.
Prepared lists as well as graphics can be viewed on the screen, printed for the result documentation or transferred to other programs.
