SAN DIEGO, Calif. - Maxwell Technologies, Inc.

Kreigler, 53, has more than 30 years of high technology operations management experience, including supervision of multiple large-scale offshore manufacturing facilities. He spent the past eight years with Quantum Corporation, most recently as corporate senior vice president and general manager of the $300 million annual revenue Quantum Storage Systems business unit. Previously, he was vice president, manufacturing systems for Read-Rite Corporation, and before that spent 12 years in senior operations and engineering positions with disk drive manufacturer Maxtor Corporation.

Dr. Richard Balanson, Maxwell's president and chief executive officer, said that Kreigler's deep and diverse manufacturing, engineering, supply chain and offshore production experience give him ideal credentials to lead the company's ultracapacitor capacity expansion ramp to keep pace with multi-million-unit annual demand Maxwell that expects in coming years.

"Ultracapacitor-based solutions for transportation and industrial applications represent a multi-billion dollar opportunity in the coming decade, and George brings the operational skills and savvy to drive the process of building the internal and external production infrastructure we need to ensure that Maxwell capitalizes on that opportunity," Balanson said.
