USA: Liebert selects active power's flywheel units

Advanced Battery Technology, Jan 2001

Active Power has received an order for 36 of its 240kW CleanSource(TM) DC flywheel units valued at more than $1 million from Liebert Corporation of Columbus, Ohio, a subsidiary of Emerson Electric Co.

The CleanSource DC is a compact, reliable, non-toxic replacement for lead-acid batteries used with uninterruptible power supply (UPS) systems. The combination of the energy storage units and Liebert's UPS systems promises to provide a key customer with a power protection solution for one of its advanced data center facilities. Delivery is scheduled for the first half of 2001.

Six CleanSource DC flywheel units will be integrated with each of six 750kVA Liebert UPS systems to provide redundant energy storage that will back up an advanced colocation facility. This configuration, when installed, will be an industry-leading, double N+ I redundant, battery-free power protection solution.

Active Power, Austin, Texas, manufactures and markets battery-free power quality solutions that eliminate power disturbances which cost U.S. industry $30 billion annually in lost data and productivity.

Liebert Corporation designs, manufactures, and distributes systems that control temperature and humidity, condition power, and guard against outages in data centers, telecommunications facilities, and Internet hosting facilities that house sensitive electronic equipment.
