Warranty File Description For the engineers and contractors specifying cooling for buildings that can't afford downtime, Axion™ is G&D's next-generation water-cooled centrifugal chiller platform — built around an oil-free magnetic-bearing compressor and high-efficiency variable-speed centrifugal compression. The result is a chiller that holds its efficiency at full load and gets even better at part load — the condition it will run at for most of its life in the field. Because the compressor has no oil system, Axion eliminates an entire category of routine maintenance while improving long-term reliability. A two-stage compression design and falling-film heat exchange keep performance strong across a wide range of operating conditions, giving facility teams a chiller that's engineered to run — not to be babysat. Key Specs Capacity: 1,200 Tons Configuration: Oil-Free, Magnetic-Bearing Centrifugal, 2-Stage (WxLxH): 15'7" x 9'5" x 8'4" Operating Weight: 34,359 lbs Request A Quote Features Oil-Free, Magnetic-Bearing Compression No oil pumps, oil coolers, or oil-related maintenance. The magnetic-bearing centrifugal compressor levitates the rotating assembly on a magnetic field, cutting friction losses and mechanical wear to virtually zero. Built for Part-Load Reality Variable-speed (VFD) operation continuously matches compressor speed to the actual load, so Axion holds its efficiency where most buildings actually operate — not just at the full-load number on the spec sheet. Two-Stage Centrifugal Design A two-stage compression path improves overall heat-absorption efficiency versus single-stage designs, supporting stable, continuous operation even under demanding conditions. Smart, Connected Controls A BACnet-ready microprocessor controller with a touchscreen interface puts real-time monitoring and building-automation integration right at the unit — and in the BMS. Engineered for Uptime Hot gas bypass keeps operation stable at low loads. Flanged evaporator and condenser connections simplify field piping. A compact, single-skid footprint speeds installation. Every unit is factory tested before it ships. Independently Verified Performance Performance is AHRI-certified to AHRI Standard 550/590, so the numbers on this page are numbers you can build a project around.
