Liebert DSE 400-500kW

More Efficient. More Flexible. Smoother Transitions.

The Liebert DSE 400-500kW solution the world's most reliable and efficient water-free cooling system for colocation, cloud hosting and other large data centers.

Offering superior reliability, the Liebert DSE uses proven pumped refrigerant economization technology from Vertiv, deployed in more than 6000 installations worldwide. It integrates the evaporator, condenser, compressors, refrigerant economizer pumps and thermal controls in a single, easy to deploy outdoor packaged solution.

The highly scalable system is available in rooftop and outdoor perimeter configurations.

BENEFITS

Save Money

- High-efficiency, with an operational PUE under 1.20
