Circlemiser is an innovative air-cooled chiller designed for outdoor installation, equipped with microchannel cylindrical condensers, flooded evaporators and oil-free, magnetic-bearing centrifugal compressors.

The Circlemiser series is characterized by outstanding performance and unmatched energy-efficiency, making it the ideal solution for mission-critical applications with high energy consumption, including high-density data centers.

Highlights:

• Unique microchannel cylindrical condensers, featuring a 45% greater heat exchange surface compared to traditional V-bank condensers
• 10% reduction in footprint compared to traditional air-cooled chillers, without compromising performance
• Turbocor oil-free, magnetic-bearing centrifugal compressors
• An increase in Energy Efficiency Ratio of up to 9.5% for single-compressor units and up to 15% for multi-compressor units, compared to equivalent oil-free chillers under the same operating conditions
• Cascade-flooded shell-and-tube evaporators reduce the ΔT on the water side, ensuring lower energy consumption and higher efficiency, as well as circuit redundancy
• Compatible with low GWP (Global Warming Potential) refrigerants, including R515B, R513A, and HFO-R1234ze
• AHRI certified
