Sapphire opens orders for data center chiller compressors

Sapphire Technologies began accepting orders for oil-free centrifugal compressors manufactured at its California facility, adding a supplier for air-cooled chillers used in AI data centers, the company announced. Sapphire says the platform can operate at temperatures up to 140 degrees Fahrenheit, where conventional compressors lose capacity and efficiency. Its two-stage design uses a permanent-magnet motor and active magnetic bearings. Build configurations support up to 8,000 tons of refrigeration per unit and include an 800 VDC power option.
