Environmental concerns related to global warming and ozone depletion triggered the introduction of the fourth generation of thermo-fluids. Amongst the recently introduced thermo-fluids, one of the most promising fourth generation thermo-fluids are Hydrofluoroethers (HFEs) . Hydrofluoroethers have zero ozone depletion potential and have a lower global warming potential as compared to widely used thermo-fluids. The type of thermo-fluid used in a thermodynamic cycle directly affects the tribological performance of the system. The friction, wear and the overall tribological performance of the recently introduced Hydrofluoroethers have to be investigated in detail in-order to fully assess the mechanical behaviour of the interacting components utilizing these thermo-fluids. This study is concerned with the experimental test rig design modifications and commissioning to conduct tribological testing with HFEs as lubricating environment.
