Atlas Copco showcases energy-efficient air solutions at REI Expo

Atlas Copco is exhibiting its portfolio of advanced compressed air and gas generation technologies at the Renewable Energy India (REI) Expo 2026 (Stall B351). Designed to support the rapid scaling of India's clean technology infrastructure, the showcase features oil-free and oil-injected air compressors, specialized dryers, filtration systems, and on-site oxygen and nitrogen generators. These utility systems provide the critical, high-purity pneumatic power required for precision manufacturing in the renewable energy landscape.

Variable speed drives and digital monitoring
To minimize the heavy electrical load typically associated with industrial compressors, Atlas Copco relies on its Variable Speed Drive (VSD) technology, which dynamically adjusts motor speed to match fluctuating plant air demands. Coupled with energy recovery solutions and centralized smart controllers, this architecture drastically reduces baseload operating costs and improves equipment uptime. Digital connectivity and continuous remote monitoring ensure that these utility systems maintain peak energy efficiency across highly automated environments, such as solar PV and wind turbine component manufacturing.

Scaling utilities for gigafactories and hydrogen
As India accelerates the deployment of battery gigafactories and green hydrogen infrastructure, the demand for highly reliable, utility-scale air and gas systems is intensifying. Bhavin Pandya, General Manager of the Compressor Technique Customer Center at Atlas Copco India, noted that optimal system design and digital monitoring are essential to building sustainable and globally competitive manufacturing operations. By generating nitrogen and oxygen directly on-site and utilizing advanced compressed air piping, manufacturers can effectively lower their carbon footprint and reduce supply chain dependencies.

Additional Context: Class 0 oil-free air and on-site nitrogen in battery gigafactories
This section details technical specifications and industrial applications not included in the original press release.

In lithium-ion battery cell manufacturing, the purity of compressed air and process gases is a critical quality control parameter. The production environment—particularly during electrode coating, calendering, and cell assembly—requires strictly ISO 8573-1 Class 0 certified oil-free compressed air. Even trace amounts of aerosolized lubricating oil or moisture in the pneumatic lines can contaminate the active battery materials, leading to internal micro-shorts or severe degradation of the cell's energy capacity. Furthermore, battery gigafactories require massive volumes of high-purity nitrogen to create inert atmospheres during electrolyte filling and sealing, preventing highly reactive lithium components from oxidizing or absorbing ambient moisture. By utilizing on-site Pressure Swing Adsorption (PSA) nitrogen generators connected directly to VSD-driven, oil-free compressors, gigafactories eliminate the heavy logistical emissions and continuous costs associated with trucking in cryogenic liquid nitrogen, directly lowering the overall Scope 3 emissions of the battery supply chain.
