In November 2024, GAIRS proudly introduced the world’s first 60 bar oil-free single screw compressor, marking a historic breakthrough in high-pressure compression technology. This revolutionary model, equipped with a 290kW motor, delivers an impressive 20m³/min at 60 bar, specifically designed for gravity-based energy storage applications at the request of a valued client.
Core Innovation: Pushing the Boundaries of Single Screw Technology
GAIRS has been at the forefront of single screw compressor development for decades, and this latest achievement is a testament to our expertise and commitment to continuous innovation. Unlike traditional twin-screw or reciprocating compressors, our water-injected oil-free single screw technology ensures exceptional durability, superior energy efficiency, and reduced maintenance costs.
The compressor’s ability to reach 60 bar without compromising efficiency or reliability is a milestone in the industry. By leveraging advanced screw rotor engineering, optimized cooling, and precision machining, GAIRS has created a system capable of handling extreme pressures while maintaining consistent, high-quality compressed air output.
Transformative Applications: Powering Gravity-Based Energy Storage
The demand for sustainable energy solutions continues to grow, and GAIRS is playing a key role in advancing energy storage technology. Gravity-based energy storage systems require high-pressure compressed air to efficiently store and release energy, making our 60 bar single screw compressor a game-changer in this sector. Precision-engineered screw profiles enable 22% reduced energy loss compared to conventional piston-type compressors in water-pumping energy storage scenarios.
Besides the hydraulic gravity storage, this innovative model can also be applied in industrial symbiosis systems and mine water management.
Expert Insights: A Milestone for the Future
Mrs. Zhu Weiyan, GAIRS’ chief R&D engineer, emphasized the significance of this breakthrough:
“Developing a 60 bar single screw compressor was a technical challenge that required innovation in structural integrity, material science, and thermal dynamics. Our 60bar model solves the dilemma between energy density and environmental safety,” said the chief engineer. “By marrying water-lubricated reliability with two-stage pressure boost, we’re enabling carbon-neutral energy storage solutions for 500kW-2MW microgrids.”
Leading the Industry Forward
As industries worldwide seek higher efficiency and cleaner energy solutions, GAIRS remains committed to pioneering advancements in air compression technology. The 60 bar single screw compressor is just the beginning of a new era, reinforcing our mission to deliver cutting-edge, environmentally friendly solutions for global energy and industrial applications.
