CHATSWORTH, CA -- The Liebert FS flywheel system, manufactured by Pentadyne Power Corporation (, the world’s leading commercial manufacturer of clean energy storage systems using advanced composite flywheel technology, has been named a Backup Power Product of the Year 2006 by, a leading information technology industry website.

Pentadyne is the original equipment manufacturer of the Liebert FS, which is marketed by Emerson Network Power (

In making their choices for Products of the Year 2006, Editor Matt Stansberry said, “Businesses are focusing on energy efficiency in the data center; the latest bells and whistles won’t win an award if it doesn’t solve real-world problems.”

“Reliably solving real-world power problems in an energy efficient manner is exactly what our flywheel product is all about,” said Pentadyne President & CEO Mark McGough. “The Liebert FS is ten times more energy efficient than low-speed, steel flywheels on the market. Emerson Network Power is one of the world’s leading manufacturers of UPS systems. Their reputation is built on the rock-solid reliability of the products they sell.

Emphasizing both the economic and environmental benefits of the Pentadyne/Liebert flywheel product, Pentadyne Senior Vice President of Sales & Service Frank DeLattre said, “Compared to a low-speed, steel flywheel, our system saves more than 20 megawatt-hours per year of otherwise wasted energy. Each Pentadyne/Liebert flywheel deployed saves a data center thousands of dollars per year in added utility costs. Being so much more energy efficient translates into a reduction in utility power plant generation and CO2 greenhouse gas emissions amounting to 30,000 pounds per year per Pentadyne/Liebert flywheel deployed.”

The Pentadyne/Liebert flywheel system can supplement or replace lead-acid battery arrays used with uninterruptible power supply (UPS) systems. Chemical battery plants require extensive, costly and lengthy permitting, testing and monitoring processes because of their corrosive materials, fire dangers, hazardous fluids and explosive gas emissions. Batteries are commonly acknowledged as the weakest reliability link in a UPS system, demanding frequent and costly maintenance and replacement. The Pentadyne/Liebert flywheel system is a more reliable method of energy storage that is far less costly to operate than a 5-minute string of VRLA batteries.

Exhibiting at upcoming trade show

Emerson Network Power will be displaying the Liebert FS in their exhibit booth at the AFCOM Data Center World Conference ( in Las Vegas March 27 and 28.
