Two freshly installed mixing loops with Grundfos MIXITs and MAGNA3 at Envases
traditional mixing loop is a cumbersome assembly of 8 to 12 separate components from multiple vendors, making design, installation, and commissioning a specialized and costly endeavor. The MIXIT unit is an all-in-one, "plug-and-play" solution that integrates these functions into a single, pre-assembled component, cutting installation and commissioning time by up to 50%. This simplifies energy optimization, allowing facility managers to implement a standardized, reliable
used to satisfy the factory's own demand for space heating. The vast majority remaining is then transferred via a heat exchanger to the district heating network, turning a waste stream into a revenue-generating asset and transforming Envases into an energy "prosumer." The technological core: The MIXIT solution The operational success of this dual-mode system hinges on precise energy management, achieved by replacing traditional mixing loops with the advanced system.
