Pentadyne Ready to Ship Second-Generation Clean Energy Storage Product

July 19, 2006

Pentadyne Power Corp. announced that the first of its second-generation VSS+DC flywheel-based clean energy storage systems has passed all tests and is ready to ship. The new VSS+DC delivers 50% more power with the same cost and footprint as Pentadyne’s previous generation system. This innovative energy storage product provides organizations with unsurpassed power protection during power disturbances assuring the highest-level of business continuity. With a design-life of 20 years operating 24x7 without any major service interval, the new system offers a significant improvement in power density, operates virtually silently, weighs only 1,300 pounds and is protected by a five-year warranty.

The original VSSDC integrated with UPS (uninterruptible power supply) systems instead of conventional chemical batteries, is on duty at a variety of commercial, industrial and military facilities ranging from the NASA Glenn Research Center to one of the world’s leading pharmaceutical manufacturers. While the original VSSDC is rated to deliver 120kW of power and up to 2,400 kW/seconds of energy, the new VSS+DC will deliver up to 190 kW of power and up to 2,700 kW/seconds of energy. For extended power outages, the unit seamlessly transfers to an engine generator for a continuous power system.

Pentadyne’s flywheel power system improves UPS reliability by completely replacing or greatly extending the life of lead-acid batteries commonly used in most UPS configurations. In comparison to such batteries, the VSS+DC improves UPS reliability while eliminating ventilation and costly cooling requirements as well as reducing lifecycle cost and maintenance/replacement needs.

By occupying less than 25% of the space of an equivalently sized battery system, the VSS+DC saves valuable floor space in the data center leading to higher computing density. The higher output VSS+DC permits integration with UPS systems rated at 225 kVA or less. Multiple units are easily paralleled without any communications gear to work with higher-capacity UPS systems and still offer exceptional space and conditioning savings over other energy storage products.
