Key Benefits

Superior Energy Efficiency

Garrett’s innovative centrifugal compressor offers significant cost savings compared to scroll compressor technology

Reduced 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
