Chatsworth, Calif. - Aug 6, 2007 - Pentadyne Power Corporation (www.pentadyne.com) - the world's leading commercial manufacturer of clean energy storage systems using advanced composite flywheel technology - announced today that one of its flywheels is now part of the power protection system for KDEN's digital television transmission facility near Denver.

The Pentadyne system is operating as the sole source of energy storage for the transmission site's uninterruptible power supply (UPS) system. UPS systems commonly use dozens of hazardous lead-acid batteries to store the energy needed to feed protected loads in the event of utility power fluctuations or complete outages. Lead-acid batteries, however, are commonly acknowledged as the weakest link in any continuous power quality system.

"Battery banks are notoriously problematic in terms of reliability, temperature control and maintenance needs," said Frank DeLattre, Pentadyne's Senior Vice President of Sales & Service. "This is particularly an issue at remote broadcast sites. Regulating battery temperature is a problem and traveling to remote locations every month to check, maintain or replace batteries is an expensive waste of time and resources."

Those were the primary re asons th at Dirk Freeman, President of Blair Media Inc. -- which develops and manages digital broadcast properties - chose a Pentadyne flywheel and a 225-kVA Toshiba G8000 UPS system to ensure con tinuous operation of the DCX Paragon MSDC-IOT at KDEN's multi-million-dollar digital transmission site.

"Over the years, we've been made painfully aware of the short-comings of UPS batteries. That's why we chose to eliminate those problems and their costs with this battery-free solution that began operating two weeks ago," Freeman said. "There are other flywheels and other UPSs, but the Pentadyne and Toshiba systems offer the best performance and they back them up with warranties that are years longer than any other on the market."

The Houston-based UPS division of Toshiba International Corporation sells the Pentadyne flywheel with their G8000 UPS line to broadcasters as well as to industrial businesses and to medical equipment installations requiring reliable, uninterrupted, high-quality power.

"The Toshiba G8000 UPS and Pentadyne flywheel cost a bit more than lowest-priced conventional options," said Greg Mack, Business Unit Manager for Toshiba's line of UPS systems. "But the rock-solid performance of these two products may provide KDEN return on investment in the next couple years. And they will continue to save KDEN money while providing higher reliability service for many years thereafter."

Pentadyne President & CEO Mark McGough noted that "Pentadyne flywheel systems are currently used by several other television stations from coast to coast, but this is the first digital transmission site. We expect it will be joined by many other such Toshiba/Pentadyne battery-free UPS installations as the nation goes to all digital television broadcasting in early 2009."

Pentadyne and Toshiba are showing the flywheel and UPS equipment in booth #321 at the August 9 Texas Association of Broadcasters/Society of Broadcast Engineers Annual Convention & Trade Show in Austin: www.tab.org/convention-and-trade-show.
