CLEVELAND, March 16, 2012 /PRNewswire/ -- Morgenthaler Private Equity ("MPE"), the Cleveland and Boston-based private equity team focused on lower middle market buyouts, announced today that it has completed the sale of Avtron Loadbank, Inc. ("Avtron Loadbank" or the "Company"), a market-leading designer and manufacturer of power integrity test and measurement devices, to Emerson (NYSE: EMR). The Company's load bank technologies test and validate the quality and integrity of power sources, such as primary and standby generators and uninterruptible power supplies, in critical applications such as data centers, hospitals, airports, telecommunications, commercial and industrial buildings, and water and wastewater utilities.

Terms of the transaction were not disclosed.

Jeff Gwinnell, President and Chief Executive Officer of Avtron Loadbank, was quoted as saying, "The combination of Avtron Loadbank with Emerson represents an exciting opportunity for growth. With the acquisition of Froment in 2010, Avtron Loadbank solidified its position as the clear global leader in load banks, and as part of Emerson we see terrific potential to further broaden our customer base and geographic reach. The entire senior management team at Avtron Loadbank thanks Morgenthaler for their constructive support over the course of our successful partnership."

Avtron Loadbank was one of three companies owned by Avtron Holdings, LLC ("Avtron"). Avtron Industrial Automation, Inc. and Avtron Aerospace, Inc. were not part of this transaction and will continue to operate under Avtron and be owned by MPE. MPE originally acquired Avtron in November 2007. Peter Taft, Chairman of Avtron and Partner at MPE added, "In partnership with management, we expanded the Company's global footprint through its acquisition of Froment which furnished a direct sales force serving Europe, the Middle East and Asia, as well as developed new product introductions and enhanced operational efficiency. On behalf of Karen Tuleta, Matt Yohe, and Constantine Elefter of MPE, it has been a pleasure working with Jeff Gwinnell, Keith Williamson (Managing Director, Froment), Bill Hatch (CFO), and the entire senior management team at Avtron Loadbank. There is no doubt that under their collective leadership the Company will continue to execute on its growth plan, as well as deliver the highest level of customer service and products to its customers."

Jones Day served as legal advisor and Harris Williams served as financial advisor to Morgenthaler Private Equity.
