Grundfos-MAGNA3The Grundfos MAGNA3 is an energy‐optimized, variable-speed wet rotor circulator featuring a permanent magnet motor design that cuts power consumption up to 85 percent, as compared with other circulators in its class. MAGNA3 offers much more than the ability to match pump speed to varying system loads. Grundfos is the only manufacturer to offer a variable-speed electronically commutated motor (ECM)-based circulator that uses an integrated logic algorithm to “learn” the varying energy-usage patterns of an application over time, enabling the software to automatically determine the lowest possible operating efficiency point to meet ever-changing demand. By continuously fine‐tuning power consumption and flow rates to meet the dynamic needs of the system, this AUTOADAPT function saves both energy and money. Grundfos says the AUTOADAPT function is so powerful that eight out of every 10 installations can rely on this feature to automatically select the optimal setting, with no additional human intervention.
