Starting from scratch, often a gap during development of new production technologies in the range of TRL 3–7 occurs. Universities responsible for the basic research cannot provide pilot or demonstration plants, while the industrial part may not have an internal engineering department or the know-how to develop this very important intermediate scale for validating the new technology. To avoid a failure in this “valley of death” of a technical development, a partner specialized for this kind of engineering tasks is very helpful. InVerTec has a lot of experience in the design and manufacturing of CE certified “miniplants” which can be operated in the industrial partner’s laboratory.
Beyond these activities InVerTec is also able to participate in the engineering team of full-scale production sites. Our part, then, is that of a source of expertise in process technology. The following examples give an overview of engineering projects accompanied by InVerTec.
