History

Ralph C. Liebert (1918–1984) founded Capitol Refrigeration Industries in 1946, which later evolved into Liebert Corporation. He created the initial precision air conditioning prototype in his garage. In 1965, this prototype was presented to IBM in Chicago and subsequently showcased at the World Computer Conference held in Philadelphia.

That same year marked the official formation of Liebert Corporation as the pioneer manufacturer of air conditioners with temperature and humidity controls specifically designed for computer rooms.

In 1977, Liebert introduced Conditioned Power Corporation to focus on designing and producing power distribution, conditioning, and monitoring equipment for data processing applications. Following the company's initial public offering (IPO) in 1981, this entity became a division within Liebert Corporation.

By 1980, Liebert inaugurated a large-scale manufacturing plant in Delaware, Ohio, with Larry L. Liebert (1945–2023), Ralph’s son, assuming leadership. The company also went public on the NASDAQ stock exchange that year.

The acquisition of Programmed Power Corporation in 1983 broadened Liebert’s power division to include uninterruptible power supply (UPS) systems. Additionally, a new manufacturing facility was launched in Cork, Ireland during that year.

Liebert created its Global Services division in 1985 and introduced SiteScan, a system for site management.

In 1987, Emerson Electric purchased Liebert Corporation for $430 million in stock. Liebert operated as an Emerson subsidiary until its integration into Emerson Network Power in 2000.

In 2016, Platinum Equity acquired Emerson Network Power and rebranded it under the name Vertiv.
