Grundfos Pumps Corp. expanded its line of fully integrated intelligent pumping systems to include motor sizes suited to HVACR applications. Ideally suited for new commercial HVACR applications and deep retrofits, the line now features the MLE variable-speed motor in ranges from 3-30 hp for building services. In all, the company will make the unified MLE motor and variable-frequency drive (VFD) available in multiple models, ranging from end-suction to inline to split-case pumping solutions. The integrated, energy optimized MLE system consists of a sensor, system controller, VFD drive, and standard asynchronous motor all in one.
