Grundfos has introduced an expanded line of fully integrated, intelligent pumping systems. Ideally suited for new commercial HVACR applications and deep retrofits, the line now features the MLE variable speed motor in ranges from 3 to 30 HP for building services. In all, the company says it will make the unified MLE motor and VFD available in multiple models, ranging from end-suction to inline to split-case pumping solutions. Grundfos has manufactured its own MLE motors to match its energy?optimized pumps. Now Grundfos is expanding that effort to include motors sizes that are suited to HVACR applications. The integrated MLE system consists of a sensor, system controller, VFD drive, and standard asynchronous motor all in one.
