Liebert AFC
500 – 1700 kW
A high-efficiency cooling solution combining adiabatic technology, free cooling coils and mechanical cooling to support reliable data center operation. Annual pPUE values as low as 1.08 can be achieved under suitable design and operating conditions.
High-Capacity Adiabatic Free Cooling Chiller
Liebert AFC
100% cooling availability and annual pPUE as low as 1.08 for large-scale data center applications.
Liebert® AFC is an advanced adiabatic free cooling solution designed for large-scale data centers and industrial facilities. Its integrated wet-pad system pre-cools incoming air through evaporation, extending free cooling operation and reducing mechanical cooling demand.
Full compressor backup helps protect critical loads by maintaining cooling capacity during water shortages and extreme ambient conditions.
Integrated Adiabatic Technology
High-efficiency wet pads pre-cool incoming air, reducing compressor load, extending free cooling operation and lowering energy consumption.
Extended Adiabatic Operation
The integrated pad system pre-cools incoming air and reduces mechanical cooling demand during warmer conditions.
Annual pPUE as Low as 1.08
Intelligent transitions between free cooling, adiabatic and mechanical modes support highly efficient annual operation.
100% Compressor Backup
Compressor backup maintains full cooling capacity during water shortages or extreme ambient conditions.
Ideal Applications
Continuous Cooling for Large-Scale Facilities
Liebert AFC is designed for large data centers requiring high cooling capacity and availability, as well as mission-critical industrial facilities where uninterrupted cooling is essential. Its integrated adiabatic system supports cooling continuity and energy-efficient operation during water shortages, extreme temperatures and demanding site conditions.
Recommended Applications
Three Cooling Modes for Maximum Efficiency
Intelligent and Autonomous Operation
Liebert® AFC continuously evaluates outdoor temperature and humidity through integrated control algorithms. It automatically selects the most suitable operating mode while balancing energy and water consumption.
Advanced Components
Liebert AFC combines high-efficiency components and intelligent controls to support system availability, reduce maintenance requirements and extend equipment service life.
