Since 1909, Piller has been a leader in designing and building motor & generator systems for industrial applications. Their motor-generator based (rotary) UPS is the most robust in the power protection industry and provides a unique building block for an array of customized power solutions. Chief among these is the engine-coupled system that can have a dual output for both “Critical loads”(computer) and “essential loads”(cooling). The option of Piller’s energy storage flywheel, the “Powerbridge”, eliminates the need for batteries, and all the headaches associated with large battery strings such as space, cooling, disposal, and reliability.
