hheader

48 individual calculation programs for the areas of pressure, flow, chemistry, energy, electrics and mechanics

hheader is a collection of 48 individual calculation programs. These 48 programs are divided into 8 different categories, each with 6 independent individual programs.

The program contents have crystallized in more than 15 years of planning and commissioning in the field of water and exhaust air treatment. The calculations and considerations that were repeatedly used, useful and helpful were collected, standardized in small programs, categorized and subordinated to a main menu. In addition to the theoretical principles, practical aspects were also incorporated into the software.

The software serves as a support for the specialist in the consideration and assessment of various contexts.

The complexity of the programs varies greatly. Some of the analyses that the software can perform can be very expensive if they are commissioned from external companies.

Values can be calculated, printed, deleted, commented, loaded and saved. In addition, comprehensive documentation and a wizard are available as instructions for each program. "You can't know everything. You can't remember everything you've learned. You can't have learned everything either. Then you have to read up."

The software is available as an executable file with an associated folder structure. It can only be used to its full extent in conjunction with a hardware dongle. The software can be started and used directly without an installation routine and is therefore portable.
