Pentadyne’s Flywheel Power System Named 2003 Product of the Year by Plant Engineering Magazine

Chatsworth, Calif. – February 17, 2004 – The new Pentadyne Voltage Support Solution™ flywheel power system has been selected as a winner in Plant Engineering magazine’s “16th Annual Product of the Year Award” for 2003. Pentadyne’s revolutionary new flywheel was voted a winner by readers of Plant Engineering after previously being nominated as a finalist by the magazine’s editors. This product of the year award is recognized as a premier honor for new products in the plant engineering market. Pentadyne’s winning product will be featured in the April issue of the publication and at the National Plant Engineering & Facilities Management Show in Chicago, February 23, 2004.

“Since the introduction of the Pentadyne VSS 120 in April 2003, the marketplace has shown great interest in our new flywheel power system,” said Paul Craig, CEO of Pentadyne Power Corporation. “In addition to being named a winner in Plant Engineering’s competition, the VSS 120 recently was named a finalist in PD&D magazine’s annual engineering awards competition.”

Pentadyne’s flywheel system provides a stable, reliable, low maintenance, extended-life DC voltage source to either replace or supplement batteries in UPS systems. The VSS 120 can completely eliminate the need for UPS batteries in many applications by providing sufficient ride-through for an orderly system shutdown or until a standby engine-generator can come on-line. To help protect batteries, the Model VSS 120 minimizes battery discharge “whiplash” effects commonly experienced with each use, thus improving battery reliability and preserving battery capacity for occasions that demand a longer back-up time. When connected to most North American UPS models, a single Model VSS 120 provides sufficient energy to support loads up to 150 kVA. Multiple VSS units in parallel provide economic ride-through for power levels up to 2 MW.
