Vertiv Holdings Co. has origins dating to 1946, when founder Ralph Liebert created an air-cooling system for mainframe data rooms. As computers began expanding into commercial use in 1965, Liebert introduced one of the first computer room air conditioning (CRAC) units, allowing precise control of temperature and humidity. Over time, the company broadened its data center portfolio through internal product development and acquisitions, adding thermal and power management solutions such as condensers, busways, and switches. Today, Vertiv operates globally, with its products used in data centers across most regions of the world.
