Cut Power Consumption of Commercial Hydronic Systems

Boasting the highest energy-efficiency rating available for circulator pumps in North America today, the MAGNA3 from Grundfos 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.

Grundfos offers a variable-speed electronically commutated motor-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 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.

MAGNA3 boasts low energy consumption, flexible range, easy installation and innovative functionalities. From its improved hydraulics and rotor system to a built-in differential pressure sensor, every detail of MAGNA3 is designed to boost efficiency. In fact, the MAGNA3 will consume 20 to 40 percent less energy than most models in the current MAGNA line. In developing the MAGNA3, Grundfos committed to achieving the European Energy Efficiency Index of 0.20, which exceeds the efficiency ratings of any circulators now on the market in North America.
