👉 The term "unhydraulic" is used in the context of hydraulic systems, particularly in hydraulic power generation. In an unhydraulic system, there is no hydraulic fluid flowing through the system or any other fluids involved in the mechanical action of the system. This can be useful for certain applications where there is limited access to hydraulic fluid, such as in remote areas or when using non-pressurized systems. However, it can also lead to problems with equipment if not properly designed and installed.
