Selection of thermostatic expansion valves

All Güntner HFC evaporators for the refrigerants R134a and R404A/R507 can be selected with mounted thermostatic expansion valve. Therefore the GPC has a TEV Module for designing thermostatic expansion valves precisely to the operating conditions: Thus you can make your selection directly in the GPC without having to use an additional program, e.g. of an expansion valve manufacturer, where you would have to enter the boundary conditions again. In the GPC’s TEV Modul the minimum condensing temperature and the designed opening degree of the TEV are calculated and output as result.
