VRT vs URI Comparison

Vertiv has roots tracing back to 1946 when its 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, or CRAC, 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.

United Rentals is the world's largest equipment rental company. It principally operates in the United States and Canada, where it commands approximately 15% share in a highly fragmented market.

As the company has grown organically and through hundreds of acquisitions since it went public in 1997, its catalog (fleet size of $21 billion) now includes a range of specialty equipment and other items that can be rented for indefinite periods. 2024 revenue totaled $15.3 billion.
