The ease for mounting the modules and the overall design of the system make it an efficient support to the hydraulic courseware. Design of the transparent modules (including inner parts issued from actual industrial fabrications) allows visualizing internal behavior of each module. It makes the training more rational and time effective. Panel consists in a perforated metal plate sheet, with 5 mm holes at 50 mm spanning. Practical works can be quickly and simply carried out. Mounting of the modules on a panel allows undertaking complete, sophisticated hydraulic circuits. Moreover, it allows developing a know how in symbolic and design of hydraulic and electro hydraulic circuits. Vocational training, technical graduation at secondary level, Polytechnics or Engineering schools use the equipment to become more familiar with hydraulic components and hydraulic techniques applying to automation. The trainer provides basic knowledge in hydrostatic and hydrodynamics, as well as inputs on physical rules applying to the design of hydraulic components.
