Product Introduction
Designed to Enhance Data Center Cooling Performance
The Vertiv™ Liebert® CRV4 thermal management solution is a row-based solution designed to provide maximum cooling in a compact footprint. This solution provides the highest efficiency and availability by removing heated air from the data center hot aisle and using it to return cooled air to the
servers (cold aisle). The Liebert CRV4 includes all of the critical functions fundamental to cooling units such as humidification, dehumidification, re-heating, air filtration, condensation management, temperature and humidity control, alarm functions, and data communications. A stand-alone, direct expansion system with variable capacity, available in both 300 mm (12, 25, and 36 kW) and 600 mm (35, 45, and 66 kW) versions, complete with the roof or wall-mounted condenser. The Liebert CRV4 series enhances capacity range as well as offers superior performance over all the available row cooling solutions in the marketplace. It is ideally suited for rack-level cooling, specifically designed for high return air temperatures. The Liebert CRV4 optimizes air distribution and maximizes efficiency, delivering both cost and economical operation. The graphical representation below shows ultra efficiency by Liebert CRV4 at different load conditions.
