Design of heat exchangers with rectangular bundles. Different media can be selected in and around the tubes. The heat transfer can be assumed to be single-phase, but also evaporation (only in the tubes) and condensation of pure substances can be calculated.
The available performance reserve and actual outlet temperatures of the media are determined (often deviating from the desired temperatures). The temperature distribution in the cross-flow is determined by means of a complex cell method. You can output the geometry of the tube sheet as a CAD file.
The program automatically determines the material properties for different media. Specific physical properties can be transferred to the program by “Free input”. This also applies to media to be condensed or evaporated.
Substance values and phase equilibria of more than 800 substances and their mixtures are to be determined with the PROPER program as an addition.
The program considers multi-pass bundles and shells. Tube pitch and arrangement are freely selectable. A variety of tube geometries is included: Plain tubes, circular, spiral and rectangular fins, lamellas, internal fins, twisted tube inserts, corrugated tubes. Shells may be round or rectangular.
When cooling air or flue gas, the condensation of moisture on the cold wall is taken into account. The heat transfer is determined according to the approach in  and the amount of water or the outlet moisture is calculated. Warnings are issued for wall temperatures below freezing as well as for very large quantities of water. Calculations of condensation processes of pure substances in the tubes and in the shell space are carried out according to the approaches of the VDI Heat Atlas . During evaporation, the heat transfer is calculated section by section.
Evaporation and condensation can be calculated completely or partially.
