The Grundfos MAGNA3 25-120 180 1x230V PN10 is a premium intelligent circulator for heating, cooling and hydronic systems. Its ECM permanent-magnet motor and AUTOADAPT logic continuously find the system’s optimum duty point — typically cutting circulator energy use by up to 75% versus fixed-speed pumps — while the built-in heat energy monitor tracks system performance without extra sensors.
Typical applications
- Commercial hydronic heating & chilled-water circulation
- Boiler primary/secondary loops, radiant systems
- Geothermal and district energy loops
