An updated version of the Güntner design software GPC for the thermodynamic design of heat exchangers is now available.

This new version offers several new features. For example, condensers can now be calculated based on the mean temperature.

This is an advantage particularly for the new refrigerant mixtures having a high temperature glide as the GPC takes into account their specific characteristics.

This way, the effects of the temperature glide on evaporators are minimized, which always allows for a precise design perfectly adapted to individual needs.

There are also three new refrigerants with low GWP available in GPC: R-454, R-455A and R-457A.

Güntner is the only manufacturer that states the refrigerant-side pressure drop on the data sheet.

This indication is a precondition for carrying out hydraulic balancing and for the energy-efficient operation of a refrigerating plant.
