This paper reports experimental testing of an adsorption dishwasher employing different desiccants, such as 13X zeolite, microporous silica gel and SAPO-34 zeolite. Thermodynamic comparison of the selected adsorbents was carried out on the basis of the experimental measurement of the main thermophysical parameters, such as specific heat, adsorption equilibrium curves and sorption enthalpy.

A sensitivity analysis on the adsorption dishwasher parameters was carried out adopting full factorial design (FFD) on a modified dishwasher prototype. Finally, the actual energetic performance for the optimized configuration were experimentally evaluated returning a consumed electrical energy of 0.636 kWh, which is 41% lower than that of standard cycle performed by a standard dishwasher with energy label A.
