Design of coiled double-pipe heat exchangers / coaxial tube heat exchangers (KOAX)

KOAX module package



Within the COIL module package (Coil tube heat exchangers) you may purchase the KOAX module package as an option. You can  perform the thermal and hydraulic design of a coiled double-pipe heat exchanger according to the regulations of the VDI Heat Atlas.


The calculations are based on the methods published in the VDI  Heat Atlas

Media are single-phase (liquid or gaseous) or condensing pure substances. The physical properties of the used media are provided by LV property modules and calculated for mean temperatures and pressures. Flow direction maybe countercurrent or cocurrent.
