The process industries are facing multiple challenges like product differentiation, shorter life cycles and market volatilities. Transformable production concepts as an answer to these challenges need a fast development of apparatuses for a short time to market but traditional scaling strategies are time and cost consuming. In contrast, innovative scaling strategies by modular process engineering promise faster scaling with less effort. The innovative scaling strategies proposed in this article include a combination of sizing-up,equaling-up and numbering-up in three main pathways. These strategies are shown and applied to examples of heat transfer, reaction and separation tasks with fluid-fluid and fluid-solid phase boundary coming from different scales.
