Grundfos Unveils MAGNA3:

Designed for commercial hydronic applications, MAGNA3 will cut power consumption up to 85 percent through its innovative AUTOADAPT function that automatically and continuously adjusts circulator performance and the new FLOWADAPT control mode that reduces the need for pump throttling valves.

Boasting the highest energy-efficiency rating available for circulator pumps in North America today, the MAGNA3 from Grundfos is at the forefront of smart pump technology. Making its North American debut at the International Air-Conditioning, Heating and Refrigerating Exposition (AHR Expo) in Dallas on Jan. 28, the Grundfos MAGNA3 is an energy optimized, variable-speed wet rotor circulator that features a permanent magnet motor design that will cut 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.

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. For the installer, that simply means plug and play and walk away.

As demand for water efficiency surges, building operators are zeroing in on the untapped potential of ultra-efficient pumps, said Jes Munk Hansen, president of Grundfos North America. Grundfos is poised to meet and exceed those demands by making smart-pump technology, smarter.
