Germany – Pumps – Los 2.4 Lieferung Pumpen Wärmespeicher

Within the framework of the project „Construction of Large Heat Storage and its Hydraulic Integration into the District Heating Distribution at the Location HKW West“ (overall project WSPW) of Stadtwerke Karlsruhe, a heat storage system is to be realised to ensure a sustainable, future-proof and secure heat supply. The process engineering task of the 2-zone heat storage system to be planned is to store and provide thermal energy as required within the district heating system. The pressureless heat storage system should enable the separate intake and discharge of heat at different temperature levels through the formation of a thermal stratification. Through hydraulic decoupling and integration into the district heating network via a separate forward and return flow system, the heat storage system should contribute to compensating for load fluctuations and to the temporal decoupling of heat generation and consumption. In this procurement procedure, functional forward and return flow pumps, as well as mixing pumps, including all components required for proper operation, are to be planned, manufactured and delivered within the specified delivery limits.
