Atlas Copco has expanded its oil-injected rotary screw compressor portfolio with three new Variable Speed Drive (VSD) ranges, giving manufacturers a broader choice of energy-efficient compressed air systems from 5 kW through to 45 kW.
The new G 22-45 VSD, GA 22-37 VSD+ and GA 5-18 VSD+ extend Atlas Copco’s VSD offering across a wider range of power ratings, with clear differentiation between the cost-effective G range and the premium GA VSD+ platform, which offers enhanced energy efficiency, connectivity and lifecycle performance.
For manufacturers looking to reduce compressed air energy consumption while controlling capital expenditure, the G 22-45 VSD covers motor sizes from 22 to 45 kW. Designed to deliver the benefits of variable speed technology without unnecessary additional features, the range offers average energy savings of up to 35 per cent compared with fixed-speed compressors by automatically matching air output to demand.
The G VSD range combines an IE5-equivalent permanent magnet motor with an oil-cooled, service-free drivetrain, engineered for reliable operation in demanding industrial environments, including hot, dusty and dirty conditions. Its compact vertical design also reduces installation footprint, while the IP65-rated SmartBox Pro and SMARTLINK remote monitoring provide advanced connectivity as standard. An Elektronikon Touch controller further simplifies operation and monitoring, with Full Feature versions incorporating an integrated refrigerant dryer.
For manufacturers prioritising maximum energy efficiency and lifecycle performance, the new GA 5-18 VSD+ and GA 22-37 VSD+ extend Atlas Copco’s premium VSD+ offering across lower and mid-range duties. The advanced variable speed technology can reduce energy consumption by up to 60 per cent compared with fixed-speed compressors, while increasing Free Air Delivery by around 20 per cent on average.
At the heart of the GA VSD+ platform is Atlas Copco’s in-house NEOS NEXT inverter technology, engineered to optimise compressor performance, efficiency and reliability. New and enhanced controller software provides improved machine control, monitoring and optimisation, helping manufacturers maintain efficient operation as production demands change.
The GA VSD+ range also incorporates improved acoustic damping, achieving sound levels as low as 62 dB(A), enabling quieter operation and greater flexibility when locating compressors closer to production areas. A streamlined design, fewer components and improved accessibility also help simplify servicing and maintenance.
Connectivity is another key feature, with SMARTLINK remote monitoring and SmartBox Pro fitted as standard. These provide enhanced visibility of compressor performance through cellular networks, Ethernet, Wi-Fi and industrial communication interfaces, supporting more informed maintenance and operational decisions.
For Full Feature GA VSD+ models, the use of R513A refrigerant in the integrated dryer also offers an environmental advantage, reducing refrigerant Global Warming Potential (GWP) by approximately 70 per cent compared with R410A, which is used in some competing systems.
Additional efficiency improvements include Atlas Copco’s integrated Smart Temperature Control system, which manages oil temperature during normal operation, while CPC+ technology removes moisture under extreme low-flow conditions. An optional energy recovery system can also recover up to 80 per cent of the compressor’s electrical energy input as usable hot water, offering further opportunities to reduce operating costs and emissions.
Jason Pollard, Business Line Manager, Industrial Air division at Atlas Copco Compressors UK, said: “Compressed air demand can vary considerably during a production shift, so manufacturers need equipment that can respond efficiently rather than simply being sized around peak demand.
“With these three new ranges, we’re giving customers greater flexibility to choose the right level of technology for their application and budget. Whether their priority is cost-effective energy savings, reliable operation in challenging environments or maximum efficiency and connectivity, the new G VSD and GA VSD+ compressors provide solutions that can help reduce operating costs while supporting long-term productivity and sustainability.”
