Air-Cooled Chillers for Data Centers
Cooling demand keeps rising, but power, water, and mechanical space remain limited. Gradian air-cooled chillers deliver scalable chilled-water capacity without the complexity of cooling towers or condenser-water systems, helping data centers expand cooling capacity faster and more efficiently.
40- to 550-ton capacity options
Scroll, screw and centrifugal compressor platforms
Air-cooled heat rejection
Modular, variable-speed and oil-free configurations
Built for Changing Demands
Multiple Paths to Capacity
Choose from modular 40-ton scroll platforms or large-capacity screw and centrifugal chillers up to 550 tons. Match cooling capacity, efficiency, and redundancy requirements to the needs of your application.
Optimized for Variable Loads
Maintain efficient operation across changing cooling demands with digital scroll modulation, compressor staging, and variable-frequency compressor control options.
Connected Controls
Integrate monitoring and operation with building management systems through BACnet and Modbus communication protocols for greater visibility and control.
Cooling Capacity Built Around Your Application
Not every cooling challenge calls for the same solution. Add capacity in manageable increments with modular scroll chillers, support large and variable loads with screw chillers, or leverage oil-free centrifugal technology for mission-critical applications at scale. Gradian helps align the right chiller platform with your facility's load profile, available infrastructure, operating priorities, and long-term growth plans.
