Vertiv™ Liebert® AFC: The Inverter Screw Chiller Range with Eco-Friendly Refrigerant from 650 to 2000 kW
Data Centre Cooling Innovation Of The Year
Entry Description
Today’s challenges facing data centre operators are related to sustainability, pollution, the greenhouse effect and global warming. Liebert® AFC, as a result of the new low global warming potential (GWP) HFO refrigerant and inverter technology, offers an eco-friendly solution, aiming to drastically reduce direct and indirect CO2 emissions into the atmosphere, and limiting the carbon footprint of the data centre.

Liebert AFC has been optimised to have very high levels of efficiency and at the same time ensures the highest levels of reliability required by modern IT applications. The inverter technology widely used for compressors, pumps and fans allows for reduced energy consumption.

The inverter-driven compressor and the innovative Liebert AFC regulation algorithms ensure accurate control of the fluid delivery temperature to the indoor units under any working condition. Cooling continuity and reliability are key factors for Liebert AFC and are granted by the Fast Restart functionality which allows for a quick and safe restart after a power failure. Liebert AFC is a solution that is well suited to different critical infrastructure applications as it is an extremely versatile and highly configurable solution.

At Vertiv we believe that sustainable product design and development is critical for the future of our industry and the greater, greener world our customers demand.
Liebert AFC Chillers are thus:
• Compatible with eco-friendly, low global warming potential (GWP) refrigerants
• Reduced risk of environmental pollution via glycol-free versions.
• Up to 20% lower annual energy consumption compared to fixed screw solutions

Moreover, in Vertiv’s Customer Experience Centre located in Tognana (Padova - Italy) customers can find the Adiabatic Freecooling Chiller Innovation Lab, a dedicated testing area aimed at validating Vertiv’s chiller range including the latest Liebert AFC units. This latest designed lab can test units with cooling capacities up to 1.5 MW with state-of-the-art accuracy in a broad range of working conditions, from -10°C to +55°C, also for adiabatic units. This laboratory is just of 7 different laboratories specifically designed for customers to interact with the entire Thermal Management data centre technologies.
