Cling selects Garrett compressor for electric bus and truck HVAC

Garrett Motion has secured its first serial production award for its oil-free, foil bearing centrifugal compressor in the mobility sector, with Chinese heating, ventilation, and air conditioning (HVAC) specialist Cling selecting the technology for integration into its next-generation electric bus and e-truck systems. Production is scheduled to begin in 2027.

The compressor operates at speeds exceeding 160,000 RPM and is designed to be up to 50% smaller, 30% lighter, and 10 dB quieter than conventional scroll compressors. It supports 400V–800V heat pump systems and is compatible with low-pressure, low global warming potential refrigerants. Garrett says the oil-free design enables up to 45,000 hours of maintenance-free operation, with the technology validated through testing at both companies during 2025.

In a statement, Olivier Rabiller, President and Chief Executive of Garrett Motion, said: “This collaboration brings Garrett’s centrifugal cooling compressor technology to electric commercial vehicle applications for the first time. By combining our high-speed, oil-free compressor architecture with Cling’s leadership in commercial vehicle HVAC systems, we are setting new benchmarks for efficiency and thermal performance.”

Junfeng Guo, General Manager of Cling, added: “This partnership will help us push the boundaries of comfort, efficiency, and environmental responsibility across China and global markets.”
