Trane collaborates on oil-free compressor technology
3rd February 2026
USA: Trane has announced a strategic collaboration to accelerate next generation, oil-free centrifugal compressor technology for commercial HVAC applications.
The collaboration with Garrett Motion, a company headquartered in Rolle, Switzerland, the developer of an oil-free high-speed centrifugal compressor technology that has already demonstrated clear performance benefits.
Together, Trane and Garrett intend to launch the next generation of high efficiency HVAC systems and accelerate the adoption of ultra-low global warming potential refrigerants.
The companies will jointly develop and integrate advanced compressor solutions across a broad portfolio of Trane systems, including unitary rooftop units, modular chillers, and large capacity chillers for a variety of applications.
Field testing and production of the jointly developed technology are scheduled to begin in 2026.
“This collaboration advances our commitment to lead the industry with high-performing, energy efficient solutions that support our customers’ decarbonisation goals,” said Mauro Atalla, Trane Technologies’ chief technology and sustainability officer.
“Garrett Motion brings deep expertise and a shared commitment to quality with their oil-free centrifugal compressor technology. Together, we are accelerating innovation that will shape the next era of sustainable HVAC systems.”
Garrett Motion debuted its oil-free centrifugal compressor technology at this week’s AHR Expo 2026 in Las Vegas, where the company announced an ambitious roadmap to launch its compressor portfolio covering cooling demands from 7 tons to 500 tons (25kW to 1,750 kW).
The collaboration with Trane establishes a framework for shared engineering, design and field testing activities across global markets. It also includes joint exploration of future applications, including high-speed centrifugal technologies for smaller capacity HVAC systems, distributed cooling and other emerging cooling needs.
“Combining this technology proven in several automotive applications with Trane’s system-level leadership enables customers to benefit from a better, more energy-efficient and cost-effective HVAC system while advancing their sustainability goals,” said Garrett Motion’s president and CEO.
