Garrett Motion Inc. announced the first serial award for its breakthrough oil-free, foil bearing-based centrifugal compressor in the mobility sector by Chinese industry leader Cling for electric buses and trucks in China. The proprietary Garrett centrifugal compressor will be integrated into Cling's next generation electric bus and truck HVAC systems, with expected start of production in 2027. The new system brings a step-change to the commercial vehicle segments, with enhanced cooling efficiency and capacity combined with significantly reduced size and noise levels.
The benefits of the technology have been proven in extensive testing at both Cling and Garrett throughout 2025. The compressor integrates an ultra-high-speed motor exceeding 160,000 RPM and an oil-free foil bearing system in a highly compact, yet powerful, package - up to 50% smaller, 30% lighter, and 10 dB quieter performance compared with traditional scroll compressors. Engineered for seamless integration across a wide range of EV platforms, the E-Cooling compressor supports 400V-800V heat pump systems and is compatible with low-pressure, low-GWP refrigerants.
Its oil-free design and up to 45,000 hours maintenance free operation - validated through rigorous global testing - help vehicle manufacturers improve vehicle energy performance, extend driving range, and meet global sustainability and durability requirements. All core technologies are developed for scalable, automotive-grade production to support global EV deployment as well as industrial applications.
