Liebert Corporation

Liebert Corporation was a global manufacturer of power, precision cooling and infrastructure management systems for mainframe computer, server racks, and critical process systems headquartered in Westerville, Ohio. Founded in 1965, the company employed more than 1,800 people across 12 manufacturing plants worldwide. Since 2016, Liebert has been a subsidiary of Vertiv.

History
Founded by Ralph C. Liebert (1918-1984) as Capitol Refrigeration Industries in 1946, Liebert Corporation was formed in 1965 as the industry's first designer and manufacturer of computer room air conditioning (CRAC) systems. Targeted to the mainframe computer data-processing market, Liebert CRAC systems were the first totally redundant, self-contained units capable of maintaining air temperature, humidity and air quality within the precision tolerances necessary for media and equipment used in these rooms and taking advantage of the raised floor plenums typically found in such rooms.

In 1977, Liebert launched a partner company named Conditioned Power Corporation to design and manufacture power distribution, conditioning and monitoring systems for the data processing industry. The company remained a wholly owned subsidiary until 1981, when it became a division of Liebert Corporation upon the company's initial public offering. The company strengthened this division in 1983 with the acquisition of Franklin Electric subsidiary Programmed Power Corporation. The acquisition expanded the capabilities of the company's power division to include the design and manufacture of uninterruptible power supplies.

Liebert Corporation was acquired by Emerson Electric Co. of St. Louis, Missouri in 1987. The company remained a wholly owned subsidiary of Emerson until 2000, when the company consolidated its network and computer protection businesses to form its Emerson Network Power platform group. As part of the Emerson Network Power platform, the Liebert and Liebert Services businesses offered power, cooling, monitoring and management solutions for critical data center applications, as well as professional services.

Following Platinum Equity's acquisition of Emerson Network Power in 2016, the business was rebranded. Liebert has since operated as a subsidiary of Vertiv.
