Oil-Free E-Cooling Compressor for HVAC
Our new oil‑free centrifugal refrigerant compressor sets a new benchmark in HVAC cooling performance, delivering high‑efficiency, foil‑bearing reliability, and a compact, maintenance‑light design.
Key Benefits
Superior Energy Efficiency
Garrett’s innovative centrifugal compressor offers significant cost savings compared to scroll compressor technology
No maintenance and cost requirements
The oil-free units significantly reduce regular maintenance costs and intervals. The risk of costly down-times and failures is significantly reduced
Enable low GWP refrigerants & Building retrofit
Unlike scroll compressors, the technology is enabling significant greenhouse gas reductions in the commercial and industrial HVAC space and facilitating building retrofits
Less noise and vibration
Noise intensity and vibration is half of comparable solutions thanks to Garrett’s centrifugal technology and extensive experience in high-speed balancing
Significantly smaller and lighter packaging
More than 80% lighter and more than 50% smaller than comparable solutions
Technology response time
Faster ramp-up and shut-down capabilities, enabling target cooling performance when urgently needed, such as heat spikes in data centers to protect the assets and ensure optimal computing performance
Extended Application Range
Solutions from 7 to 500 tons for diverse applications, from mobility to rooftop units and chillers.
Rooftop HVAC & Heat Pumps
Smaller units, lower noise, easier retrofits when switching to low GWP refrigerants
Industrial and Data Center Cooling
Operation under higher suction temperature, compact, high-reliability thermal management
Battery Energy Storage Systems (BESS)
Space-efficient cooling under all conditions
Air Conditioning in Tight Spaces
Flexible integration for space-limited designs
