The Krombacher brewery is one of the leading pre-mium breweries in Germany. Installed in autumn 2015, three DPA UPScale ST UPS systems by ABB protect the company’s production, filling and logistics center in Krombach.
In 2015, the brewery delivered an all-time high in terms of output and sales revenues and sold 4.26 million hectoliters of Krombacher Pils alone, their flagship product. In order to ensure a continuous production and logistics of such large quantities, the supply of uninterruptible, clean i.e. undisturbed power has to provided.
With the decision for the replacement of the aged UPS installation with state-of-the-art UPScale ST systems in 2015, the brewery made the step towards modular UPS technology.
One important argument for the ABB solution was the decentralized parallel architecture (DPA) of the DPA UPScale ST modules. Each system consists of autonomous UPS modules containing the complete hardware and software required for the operation of the overall system. In the worst-case event when one UPS module fails, the overall system continues operation with the capacity of one module less (N+1-redundancy).
“In regard to fail-safety, the concept of a modular exchange was the crucial criteria. Using 10 or 20 kVA modules, each system featured good scalability according to the respective power requirements“, Timo Kleinsorge , from Krombacher Brauer states.
Timo Kleinsorge sees the benefits of the new solution in an increased flexibility, availability and cost-effectiveness: “The systems are optimally designed for the required performance and not over-dimensioned. Through modular technology, we can easily expand the systems without having to purchase a new UPS system. Furthermore, the N+1-concept provides maximum availability“.
