Defense Contractor Orders Flywheel UPS Systems

Pentadyne Power has received a follow-on order worth $4.5 million from Beaver Aerospace & Defense for an additional 100 Pentadyne VSS+DC systems with DX-A2 rating (certified for national defense use). This latest order is part of a procurement contract with Pentadyne to be the exclusive supplier of more than 500 clean energy storage systems that will be deployed in homeland security military defense applications during the next few years.

Beaver Aerospace Program Manager Jim Diroff said, "We've installed quite a few of these so far, installing them is practically plug-and-play. They've reliably discharged and rapidly recharged flawlessly every time we've needed them."

The Pentadyne VSS+DC stores energy kinetically instead of chemically, delivering stable, reliable dc voltage for energy recycling and power-continuity applications. In these Department of Defense energy-recycling applications, the flywheel system periodically absorbs regenerative energy and stores it until it is later reused. This is similar to the way hybrid vehicles capture deceleration energy and store it in chemical batteries, later releasing that energy to aid acceleration and minimize fuel consumption.
