Magnetek Announces Vanadium Redox Energy Storage System for Wireless Cell Sites

DALLAS, TX - April 19, 2006 - Magnetek, Inc. (NYSE: MAG), a leading developer of power conversion, alternative energy and utility grid management systems, and VRB Power Systems Inc. (TSX-V: VRB), a leading producer of energy storage systems, have announced the unveiling of a revolutionary FkW energy storage system is an alternative to traditional lead-acid battery backup systems. It provides cost effective, reliable, environmentally friendly, virtually maintenance-free backup power for wireless cell sites and other telecommunications facilities. Based on VRB Power’s patented Vanadium Redox Battery Energy Storage System (“VRB-ESS”), the 5kW system is comprised of an electrolyte storage tank containing a vanadium-based electrolyte supplied to a regenerative cell stack that converts chemical energy into electrical energy. A chemical reaction in the flow-cell stacks a current that is collected by electrodes and made available to an external circuit. This reaction is reversible, allowing recharging of the DC power modules.

The VRB-ESS is well suited for a variety of applications. Virtually maintenance-free, it affords substantially lower cost of ownership than lead-acid battery-based systems and provides unprecedented security-of-supply to meet the energy needs of critical telecommunications facilities. In addition, the system's small footprint is a bonus for cell site where space is limited.  

With its precise state-of-charge monitoring and extremely rapid recharge rate, the VRB-ESS is ready to perform whenever an AC utility grid outage occurs, and when power is restored it returns to backup duty faster than any other system available. Environmentally friendly and competitively priced, the VRB-ESS unit is the backup system of choice where high-reliability power is needed. Incorporating "green" technology, it has negligible ecological impact, distinguishing it from conventional energy storage systems that rely of toxic substances such as lead and cadmium.
