These systems represent the keystone of an artisanal or industrial unit and are composed of a principal pipe gallery where come to be grafted various modules of work either linear, or grouped. Some of these technical elements are equipped with systems of convoying and with handling operations automated to serve either of the machine tools, or of the manual systems or robotized systems. The central element is composed of two galleries of communication inter modular linear. The lower element, connecting two or four modules, is a gallery of supply and of distribution of the products in the course of transformation. A higher gallery of transit supplies and distributed the products in progress of development. Between the two, a transit of the gas fluids, liquid and thick is carried out, including the provisioning of energy of the various modules and sectors of work. At the subjacent level of the unit does a gallery of outward journey and return of the products have to undergo certain specific treatments like ionization for example. This key and its components thus allow composition of Modular Centers of Transformations of Multi Products Productions on the same site by developing centers of productions being able to be about a few hundred square meters to lead in time and according to the needs, in centers about several thousands of square meters.
