1. Product Description Liebert CRV installs within a row of data center equipment racks, providing precision cooling close to the server heat source for the most efficient and effective operation. The combination of Liebert iCOM controls, digital scroll compressor and EC plug fans ensure reliability and energy efficiency. Flexibility
Horizontal airflow cooling design is suitable for non-raised or raised floors. Adjustable airflow baffles maximize cooling to rack equipment, allowing the
system to be positioned within the row or at the end of the row. Air, water, glycol, and chilled water systems available. Caster mounted for easy placement. Multiple units communicate with each other to improve system performance and
reduce energy consumption. Can be used with Liebert SmartAisleTM containment system.
Lowest Total Cost of Ownership
Designed for higher return air temperature to maximize cooling capacity and increase efficiency.
Only front and back access required, resulting in minimized installation and service time.
Digital Scroll compressor and variable speed EC fans operate efficiently to reduce energy consumption and provide longer component life.
Compact cabinet minimizes floor space requirements.
High Availability Self-adapts to changing conditions to provide 24/7 precision environmental
control: cooling, humidity control and air filtration. Liebert iCOM control provides alerts for preventive maintenance before issues
occur. Variable capacity Digital Scroll compressor adapts to load and eliminates
compressor cycling, greatly increasing compressor life. Ideal Applications
Small to medium-sized data centers – From 2 to 24 racks – Optimal for cold/hot aisle configurations
Heat density up to 10 kW/rackwithout containment. Raised and non-raised floors. Rooms with a low ceiling where air cannot be ducted. SmartAisleTM containment system. Spot cooling in large data centers.
