THE MAGNA 3 CIRCULATOR is designed for commercial hydronic applications. Boasting the highest energy efficiency ratings available for circulator pumps in North America today, this variable-speed, wet-rotor unit features a permanent magnet motor design that can cut power consumption up to 85%. This ECM-based circulator 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, the Magna 3 saves both energy and money.
