Vertiv 

Vertiv's roots trace back to 1946, when founder Ralph Liebert developed an air-cooling system for mainframe data rooms. As computers started making their way into commercial applications in 1965, Liebert developed one of the first computer room air conditioning units, enabling the precise control of temperature and humidity. The firm has slowly expanded its data center portfolio through internal product development and the acquisition of thermal and power management products like condensers, busways, and switches. Vertiv has global operations today; its products can be found in data centers in most regions throughout the world.
